GENERAL DESCRIPTION The TEA1069 and TEA1069A contain all the functions needed to build a highly featured, high-performance fully electronic telephone set. The device incorporates a speech/transmission part, a dialler part and a ringer part. By offering a wide range of possible adaptations for each part, the TEA1069 and TEA1069A application can be easily adapted to meet different requirements. The TEA1069A offers some different timings and diode options compared to the TEA1069. Where pin numbers are mentioned in this data sheet we refer to the TEA1069N, unless otherwise indicated. Speech part The speech/transmission part performs all speech and line interface functions required in electronic sets. It operates at line voltages down to 1.6 V DC to facilitate the use of more telephones connected in parallel. Dialler part The dialler part offers a 32-digit Last Number Redial (LNR) and 13 memories. Hands-free control is included allowing the TEA1069 and TEA1069A to be used not only in basic telephones, but also in feature phones offering hands-free dialling via the TEA1083 call-progress monitor IC and/or full hands-free operation via the TEA1093 hands-free IC. The hold function allows the user to suspend the conversation and resume the call either on the same phone or on a parallel phone. Additionally through the music-on-hold function a melody is transmitted while the set is put on hold. The keytones provide in a buzzer an audible feedback of a valid key pressed.

FUNCTIONAL DESCRIPTION Speech part For numbering of components refer to Figs 28 and 29. SUPPLIES VCC, LN, SLPE, REG AND STAB Power for the IC and its peripheral circuits is usually obtained from the telephone line (see Fig.4). The circuit creates a stabilized voltage (Vref = 3.7 V) between LN and SLPE. This reference voltage is temperature compensated and can be adjusted by means of an external resistor RVA. It can be increased by connecting an RVA resistor (R60) between REG and SLPE or decreased by connecting an RVA resistor (R61) between REG and LN. This internal voltage reference is decoupled by capacitor C3 between REG and VEE.
This decoupling capacitor realises the set impedance conversion from its DC value to its AC value in the audio frequency range. The internal transmission part of the circuitry (including the earpiece amplifier) is supplied from VCC. This voltage supply is derived from the LN voltage via a dropping resistor (R1) and must be decoupled by a capacitor (C1) between VCC and VEE. This supply point may also be used to supply the dialler/ringer (VDD) part or external circuit e.g. electret microphone. The DC current flowing into the set is determined by the exchange supply voltage Vexch, the feeding bridge resistance Rexch and the DC resistance of the telephone line Rline. When the line current (Iline) is more than 0.5 mA greater than the sum of the IC supply current (ICC) and the current drawn by the peripheral circuitry connected to VCC (Ip), the excess current is shunted to SLPE via LN. 7

Thus, the regulated voltage on the line terminal (VLN) can be calculated as: V LN = V ref + I SLPE x R9 , where
-3 I SLPE = I line - I CC + I p + 0.5 x 10 A
at 1 mA). This means that more sets can be operated in parallel with DC line voltages (excluding the polarity guard) down to an absolute minimum voltage of 1.6 V. At line currents below 9 mA the circuit has limited sending and receiving levels. Under normal conditions, when ISLPE >> ICC + 0.5 mA + Ip, the static behaviour of the circuit is that of a 3.7 V regulator diode (Vref) with an internal resistance equal to that of R9. In the audio frequency range the dynamic impedance is largely determined by R1. Figure 5 shows the equivalent impedance of the circuit. Current (Ip) available from VCC for the dialler part and peripheral circuits depends on the external components used. Figure 6 shows this current for VCC > 2.2 V. When MUTE is HIGH i.e. when the receiving amplifier (supplied from VCC) is driven, the available current is further reduced. Current availability can be increased by connecting the supply IC TEA1081 in parallel with R1, or by increasing the DC line voltage by means of an external resistor (RVA = R60) connected between REG and SLPE.
Vref is the internally generated temperature compensated reference voltage of 3.7 V and R9 is an external resistor connected between SLPE and VEE. The circuit has an internal current stabilizer operating at a level determined by resistor R5 connected between STAB and VEE. In normal use the value of R5 would be 3.6 k and the value of R9 would be 20 . Changing the value of R5 or R9 will affect microphone gain, DTMF gain, gain control characteristics, sidetone level, maximum output swing on LN and the DC characteristics (especially at low line current). At line currents below 9 mA the internal reference voltage is automatically adjusted to a lower value (typically 1.6 V

MICROPHONE INPUTS MIC+ AND MIC- AND GAIN PINS GAS1 AND GAS2
TEA1069; TEA1069A
The circuit has symmetrical microphone inputs. Its input impedance is 64 k (2 x 32 k) and its voltage gain is typically 52 dB (when R7 = 68 k). Dynamic, magnetic, piezoelectric or electret (with built-in FET source followers) microphones can be used. Microphone arrangements are illustrated in Fig.7.

Fig.7 Alternative microphone arrangements.
The gain of the microphone amplifier can be adjusted between 44 dB and 52 dB to suit the sensitivity of the transducer in use. The gain is proportional to the value of R7 which is connected between GAS1 and GAS2. Stability is ensured by two external capacitors, C6 connected between GAS1 and SLPE and C17 connected between GAS1 and VEE. The value of C6 is 100 pF but this may be increased to obtain a first-order low-pass filter. The value of C17 is 10 times the value of C6. The cut-off frequency corresponds to the time constant R7 x C6. RECEIVING AMPLIFIER IR, QR AND GAR The receiving amplifier has one input (IR) and one output (QR). Earpiece arrangements are illustrated in Fig.8. The IR to QR gain is typically 31 dB (when R4 = 100 k).
It can be adjusted between 20 and 31 dB to match the sensitivity of the transducer in use. The gain is set with the value of R4 which is connected between GAR and QR. The overall receive gain, between LN and QR, is calculated by subtracting the anti-sidetone network attenuation (32 dB) from the amplifier gain. Two external capacitors, C4 and C7, ensure stability. C4 is normally 100 pF and C7 is 10 times the value of C4. The value of C4 may be increased to obtain a first-order low-pass filter. The cut-off frequency will depend on the time constant R4 x C4. The output voltage of the receiving amplifier is specified for continuous-wave drive. The maximum output voltage will be higher under speech conditions where the peak to RMS ratio is higher.

DUAL TONE MULTI-FREQUENCY INPUT DTMF When the DTMF input is enabled (MUTE is LOW) dialling tones may be sent on to the line. The voltage gain from DTMF to LN is typically 25.5 dB (when R7 = 68 k) and varies with R7 in the same way as the microphone gain. The tones can be heard in the earpiece at a low level (confidence tone). AUTOMATIC GAIN CONTROL INPUT AGC Automatic line loss compensation is achieved by connecting a resistor (R6) between AGC and VEE. The automatic gain control varies the gain of the
microphone amplifier and the receiving amplifier in accordance with the DC line current. The control range is 5.8 dB which corresponds to a line length of 5 km for a 0.5 mm diameter twisted-pair copper cable with a DC resistance of 176 /km and average attenuation of 1.2 dB/km. Resistor R6 should be chosen in accordance with the exchange supply voltage and its feeding bridge resistance (see Fig.9 and Table 1). The ratio of start and stop currents of the AGC curve is independent of the value of R6. If no automatic line-loss compensation is required the AGC pin may be left open-circuit. The amplifiers, in this condition, will give their maximum specified gain.

SIDETONE SUPPRESSION Suppression of the transmitted signal in the earpiece is obtained by the anti-sidetone network comprising R1//Zline, R2, R3, R8, R9 and Zbal (see Fig.10). The maximum compensation is obtained when the following conditions are fulfilled: R9 x R2 = R1 x ( R3 + R8 ) (1) ( R8 + R9 ) k = R3 x ---------------------------( R2 x R9 ) Z bal = k x Z line (2) (3)
TEA1069; TEA1069A
follows: suppose Zline = 210 + (1265 //140 nF) representing a 5 km line of 0.5 mm diameter, copper, twisted-pair cable matched to 600 (176 /km; 38 nF/km). When k = 0.64 then R8 = 390 ; Zbal = 130 + (820 //220 nF). The anti-sidetone network for the TEA1069 and TEA1069A shown in Fig.10 attenuates the signal received from the line by 32 dB before it enters the receiving amplifier. The attenuation is almost constant over the whole audio-frequency range. Figure 11 shows a conventional Wheatstone bridge anti-sidetone circuit that can be used as an alternative. Both bridge types can be used with either resistive or complex set impedances. More information on the balancing of anti-sidetone bridges can be found in our publication "Applications Handbook for Wired telecom systems, IC03b", order number 9397 750 00811.
The scale factor k is chosen to meet the compatibility with a standard capacitor from the E6 or E12 series for Zline. In practice, Zline varies considerably with the line type and length. Therefore, the value chosen for Zbal should be for an average line length thus giving optimum setting for short or long lines. Example: the balance impedance Zbal at which the optimum suppression is present can be calculated as

Dialler and ringer part SUPPLY VOLTAGE: PINS VDD AND VEE The power supply must be maintained for data storage. The RAM retention voltage (standby supply voltage) may drop down to 1.0 V. Applying a large capacitor across the supply terminals can retain the memory if power connections are broken. The minimum operation voltage is 2.5 V. The internal power-on reset is enabled for a voltage below this minimum operation voltage. OSCILLATOR INPUT/OUTPUT: PINS XTAL1 AND XTAL2 Time base for the TEA1069 and TEA1069A is a crystal-controlled on-chip oscillator which is completed by connecting a 3.579545 MHz crystal or ceramic resonator between XTAL1 and XTAL2. The oscillator starts when VDD reaches the operation voltage level and CE/FDI = HIGH. The following types of ceramic resonators are recommended: * Kyocera PBRC3.58ARPC10 (wired) * Kyocera KBR3.58MSATRPC10 (SMD) * Murata CSA3.58MG310VA (wired). RESET INPUT: PIN RESET Pin RESET is an input to the internal reset circuit. When RESET = HIGH, it can be used to initialize the TEA1069 and TEA1069A which is normally done by the CE/FDI input. The on-chip power-on reset generates a reset pulse if VDD drops below 2.5 V. In this event a proper start-up
occurs after the supply voltage rises above the minimum operation voltage level again. During and directly after reset pins 14 to 19, 21, 29 to 32, 34 and 35 are set HIGH; pins 8, 20, 22, 26 to 28 and 33 are set to LOW. The RESET pin can be connected to VEE, preferably via a resistor of 100 k to 1 M, which will save leakage current. A capacitor connected to VDD can be used to extend the reset time, in case a longer reset is desirable. To prevent the dialler from reacting on voltage disturbances on the telephone line a time-out is active. The dialler returns to standby state if the voltage on the line has disappeared for more than this reset-delay time (trd). CHIP ENABLE/FREQUENCY DISCRIMINATOR INPUT: PIN CE/FDI This active HIGH input is used to initialize part of the system, to select the on-line, standby, or ringer mode and to detect line power breaks. To keep the TEA1069 and TEA1069A in the on-line mode, CE/FDI has to be HIGH. In the exchange, several AC signals can be superimposed on the DC signal, e.g. dialling tone, busy tone, disturbances (like line power breaks), and the ringer signal. The ringer signal is evaluated, and checked if its frequency is within the limits of the frequency interval as set by the diode option RFS. It is assumed that the ringer frequency at pin CE/FDI is the double of the frequency present on the telephone line.

For the hands-free state refer to Fig.23. PULSE DIALLER: PINS DP/FL, MOH/DMO AND MUTE The pulse dialling system uses line current interruptions to signal the digits dialled to the exchange. The number of line current interruptions corresponds with the digit dialled except for the digit [0] which is characterized by 10 interruptions. Before each digit there is an inter-digit pause. Valid keys are the digits [0] to [9] and [PAUSE]. The pulse dialling mode, the make/break ratio and the access pause time depend on the diode options: PTS, M/B, APT and APT2. DP/FL is LOW when VDD is below power-on reset trip level and when RESET is HIGH. The MOH/DMO pin (diode GOS = on) is used to reduce the voltage swing over the a/b terminals during pulse dialling. Several countries require this feature. The MUTE pin is an open drain output which requires a pull-up resistor. MUTE is HIGH when VDD is below power-on reset trip level and when RESET is HIGH. Figure 13 shows the timing diagram in pulse dialling mode when keys [3], [RECALL] and [4] are pressed.

TONE DIALLER: PINS TONE AND MUTE In this system digits are transmitted as two tones simultaneously, the so called Dual-Tone Multi-Frequency (DTMF) system. Tone digits are separated by a pause time. Valid keys are the digits [0] to [9], [], [#] and [PAUSE]. The DTMF dialling mode, the tone burst/pause times and the access pause time depend on the diode options: PTS, TBT, APT and APT2.
The MUTE pin is an open drain output which requires a pull-up resistor. MUTE is HIGH when VDD is below power-on reset trip level and when RESET is HIGH. Figure 14 shows the timing diagram in tone dialling mode when successively keys [3], [3], [RECALL] and [4] are dialled.

KEYBOARD: PINS ROW1 TO ROW5 AND COL1 TO COL6 The sense columns inputs and scanning rows outputs are directly connected to a single contact keyboard matrix. A second key entry will be valid after having released the first button and after having pressed the second button. Simultaneously pressing 2 buttons will disable the first entered key. A key entry becomes valid when the debounce time td has elapsed.
The column and row pins (except ROW5) are HIGH when VDD is below power-on reset trip level and when RESET is HIGH. ROW5 is an open-drain input/output; this configuration is used to avoid current flowing in the on-line or standby state. A pull-up resistor should be connected to ROW5. ROW5 is LOW when VDD is below power-on reset trip level and when RESET is HIGH.

KEY TONE: PIN KT/EARTH Every time a valid key is pressed a keytone is generated with a frequency of 606 Hz and a duration of 30 ms. This function is selected by the diode GOS = off. KT/EARTH is LOW when VDD is below power-on reset trip level and when RESET is HIGH. VOLUME CONTROL: PINS VOL1 AND VOL2 Both pins can control the volume of the ringer and/or the hands-free circuit. The state of VOL1/VOL2 is controlled by a state machine as depicted in Fig.24. VOL1 and VOL2 are push-pull outputs. Both are set LOW when VDD is below power-on reset trip level and when RESET is HIGH. MUSIC-ON-HOLD: PIN MOH/DMO When the dialler is in the hold state (see Fig.23) a melody is generated via pin TONE. In this state pin MOH/DMO can be used via diode GOS = off as an enable signal for the hardware to indicate that the tone should be switched to the telephone line. MOH/DMO is a push-pull output. It is set LOW when VDD is below power-on reset trip level and when RESET is HIGH. HANDS-FREE: PIN HF
TEA1069; TEA1069A
During the on-line state, the hands-free output pin HF is used for enabling the hands-free hardware. The pin will change state depending on specific key-sequences (see Fig.23). HF is a push-pull output. It is set LOW when VDD is below power-on reset trip level and when RESET is HIGH. HOLD MODE: PIN HOLD One way to terminate the hold state (see Fig.23) is a change in state of the signal at pin HOLD. This input should reflect the line current. If current is flowing the signal at pin HOLD should be HIGH, if not it should be LOW. This pin is not debounced. The signal applied should be filtered by the hardware. HOLD is HIGH when VDD is below power-on reset trip level and when RESET is HIGH. Key sequences The behaviour of the TEA1069 and TEA1069A can be modelled as a State Transition Diagram (STD) shown in Fig.21.

The STD contains the states (rectangles in the figure) and state transitions (arrows) of the set. The upper arrow in the figure pointing to the standby state means that the set is initially in the standby state. When for instance an incoming call is detected, the set enters the ringer state, waiting for a reaction of the user. If the user answers the call on a handset, the set enters the on-line state. The TEA1069 and TEA1069A have 3 basic states: * Standby state * Ringer state * On-line state. Each state with its own functional requirements is described in the following sections. STANDBY STATE In standby state the TEA1069 and TEA1069A are inactive. The current drawn is for memory retention and depends on the loads of the inputs/outputs of the dialler. In this state output DP/FL is HIGH so that the line is disconnected. The ICs leave the standby state if: * The set goes off-hook (lift handset or press [HOOK]) * A ringer-signal is available on the line. The ICs go to the standby state if: * The set goes on-hook (handset on the cradle or press [HOOK]) * A line-break occurs for at least the reset delay time (trd) * The ringer-signal becomes invalid. RINGER STATE
TEA1069; TEA1069A
If the set is in standby mode, a ringer signal can be received from the line. After evaluating the incoming ringer signal (and ringer signal is valid), the TEA1069 and TEA1069A start a melody via the TONE output ringer hardware, and stops this melody if the ringer signal is not valid any more. After going off-hook, the ringer signal stops and the set is in conversation (on-line) state. During a ringer burst the ringer volume can be changed according to Fig.24 and melodies can be changed according to Table 7. Table 7 Melody selection MELODY Bell 1 Bell 2 Bell 3 Bell 4 ON-LINE STATE In this paragraph all the actions of the TEA1069 and TEA1069A during on-line state are described. The on-line mode starts with making output DP/FL LOW, which makes line current flow possible. The on-line state contains a number of sub-states (see Fig.22): * Conversation state * Dialling state * Memory recall state * Program state. KEY [1] [2] [3] [4]

Fig.23 Conversation states.
* Handset state. The conversation states are shown in Fig.23. * Hands-free state. In hands-free mode output HF becomes HIGH which activates a TEA1093/1094 hands-free IC. This state can be reached from standby state and from the handset state as follows: - the [HOOK] key is pressed during standby mode - the [HOOK] key is pressed during handset state is lifted, then when the handset is put on the cradle the set stays in the hands-free mode. The set leaves the hands-free mode and output HF becomes LOW when: - the [HOOK] key is pressed and the handset is on the cradle, the set goes to the standby mode - the [HOOK] key is pressed and the handset is lifted, the set goes to the handset state. The volume on the loudspeaker or buzzer, in hands-free and ringer mode, can be controlled in four levels using the [VOL+] and [VOL-] keys.
The hands-free volume can be changed according to Fig.24. * Hold state. The hold state is entered when the [HOLD/MUTE] key is pressed (diode HMS = on). This state can be entered either from handset state or from hands-free state. Upon entering this state outputs HF and MUTE become LOW. In hold state a music-on-hold melody is generated by output TONE. Pin MOH/DMO is HIGH (diode GOS = off) during this state. This signal can be used to adjust the volume of the TONE pin. Since MUTE is LOW the TONE output is transmitted to the telephone line. As long as the TEA1069 and TEA1069A are in this state the HOLD input pin is tested. The set leaves the hold state when: - [HOLD/MUTE] is pressed, the set returns to either the handset or hands-free state - the HOLD input becomes LOW, now the TEA1069 and TEA1069A return to the standby state.

* Mute state. When the [HOLD/MUTE] key is pressed (HMS = off) the mute state is entered and MUTE becomes LOW. In mute state a music-on-hold melody is generated by output TONE. Pin MOH/DMO is HIGH (diode GOS = off) during this state. This signal can be used to adjust the volume of the TONE pin. Since MUTE is LOW the TONE output is transmitted to the telephone line. The mute state is left when: - [HOLD/MUTE] is pressed, set returns to either handset- or hands-free state - a dial action is started.
PULSE DIALLING

However when keying-in is much faster then dialling-out, then the 32 digit dialling register will overflow. When this occurs the dialling is stopped and the error beep will be generated. There are two dial modes: pulse dialling and tone dialling. The initial dialling mode is determined by option PTS. The state machine which controls the dial mode is shown in Fig.25.

* Pulse dialling. In this mode all valid keys are dialled by the pulse dialler. When during pulse dialling key [/T] is pressed, the TEA1069 and TEA1069A switch over to tone dialling (mixed mode dialling). After the switch-over, valid keys are dialled by the tone dialler. The temporary tone mode is terminated by going on-hook or recall. * Tone dialling. The ICs convert valid keys into data for the on-chip DTMF generator. Tones are transmitted via output TONE with minimum tone burst/pause duration. The maximum tone burst/pause duration is equal to the key pressing/release time. * Register recall (flash/earth). The [RECALL] key will result in a flash or earth action. * Access pause. When the [PAUSE/LNR] button is not the first key pressed, an access pause is entered for repertory or redialling procedures. When an access pause is executed MUTE is HIGH. During manual dialling no access pauses are dialled. * Last Number Redial (LNR). If the first key pressed is the [PAUSE/LNR] button, the number stored in the redial register is recalled and transmitted. A maximum number of 32 digits can be

During the dial-keys entries the TEA1069 and TEA1069A start immediately with transmission of the digit(s); the minimum transmission time is unaffected by the speed of the entry. Transmission continues as long as further dial-keys entries have to be processed.

accepted for last number redial. If this maximum is reached the redial function is inhibited. During LNR programmed access pauses are also dialled. The [RECALL] key and the (in pulse dialling mode allowed) tone switch key [/T] are also stored in LNR memory. * Notepad function. In conversation state it is possible to store a number into the LNR register, which may be dialled after an on-hook/off-hook action. The procedure is as follows: - press [STORE] - press to-be-stored sequence of the digits [0] to [9], [PAUSE/LNR], [/T] or [RECALL] - press [STORE] - press [PAUSE/LNR].
TEA1069; TEA1069A
- press one of the numeric keys [0] to [9], corresponding to the memory location or - press [STORE] - press to-be-stored sequence of the digits [0] to [9], [PAUSE/LNR], [/T] or [RECALL] - press [M1] to [M10]. For storing the redial number in repertory use: - press [STORE] - press [PAUSE/LNR] - press [MRC] - press one of the numeric keys [0] to [9], corresponding to the memory location or - press [STORE] - press [PAUSE/LNR] - press [M1] to [M10]. If the keyboard described in Fig.17 is selected by the KBS diode option, repertory memory place [M1] = [MRC] + [1] to [M10] = [MRC] + [0], thus the set has 10 repertory numbers which can be selected via two different ways. If the keyboard described in Fig.19 is selected by the KBS diode option repertory memory place [MRC] + [0] to [MRC] + [9] and [M1], [M2] and [M3] are different repertory numbers, thus this set has in total 13 repertory numbers. * Memory overflow. A maximum of 224 digits can be stored in the repertory memories. When the maximum is reached, no keytone is generated when trying to store more digits. The store procedure is cancelled automatically. * Clear repertory number. Clearing a memory location is possible via the same procedure as for storing a number, except no telephone number is entered, thus one of the following sequences must be used: - press [STORE] - press [MRC] - press one of the numeric keys [0] to [9], corresponding to the memory location or - press [STORE] - press [M1] to [M10].
Memory recall state
Repertory numbers can be dialled-out after or before entering manual dialling, last number redial and by entering the memory locations in successive order. The stored numbers can be dialled by the following procedures: * Press [MRC] * Press one of the numeric keys [0] to [9], corresponding to the memory location or * Press one of the direct memory keys ([M1] to [M10]).
Program state
The program mode can be entered from the conversation (on-line) mode. Pressing the [STORE] key in this state puts the TEA1069 and TEA1069A in the program mode. The program state can be left by going on-hook (by putting the handset on the cradle or pressing the [HOOK] key), the program mode is interrupted and nothing is stored, or by ending the store procedures resulting in a proper store of the programmed item. * Programming repertory numbers. Storing of a new repertory number including access pauses, tone switch and register recall can be done by the following procedures: - press [STORE] - press to-be-stored sequence of the digits [0] to [9], [PAUSE/LNR], [/T] or [RECALL] - press [MRC] 1998 Jan 08 27

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). SDIP SOLDERING BY DIPPING OR BY WAVE The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. REPAIRING SOLDERED JOINTS Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds. QFP REFLOW SOLDERING Reflow soldering techniques are suitable for all QFP packages. The choice of heating method may be influenced by larger plastic QFP packages (44 leads, or more). If infrared or vapour phase heating is used and the large packages are not absolutely dry (less than 0.1% moisture content by weight), vaporization of the small amount of moisture in them can cause cracking of the plastic body. For more information, refer to the Drypack chapter in our "Quality Reference Handbook" (order code 9397 750 00192). 1998 Jan 08 40
TEA1069; TEA1069A
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 50 and 300 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250 C. WAVE SOLDERING Wave soldering is not recommended for QFP packages. This is because of the likelihood of solder bridging due to closely-spaced leads and the possibility of incomplete solder penetration in multi-lead devices. CAUTION Wave soldering is NOT applicable for all QFP packages with a pitch (e) equal or less than 0.5 mm. If wave soldering cannot be avoided, for QFP packages with a pitch (e) larger than 0.5 mm, the following conditions must be observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The footprint must be at an angle of 45 to the board direction and must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. REPAIRING SOLDERED JOINTS Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.
