Reflow Soldering When reflow soldering, please observe below conditions. (When you use in lead free solder,please consult before hand) Reflow Soldering Profile (A)Heat-up zone 1 Room-temp. to preheat zone: 30 s to 60 s (B)Preheat zone 140 deg.C to 160 deg.C : 60 s to 120 s (C)Heat-up zone 2 Preheat zone to 200 deg.C : 20 s to 40 s (D)Melting-heat zone Peak-temp. : 5 s max Refer to the following(200 deg.C or more) graph. (E)Cooling zone 200 deg.C to 100 deg.C : 1 deg.C/s to 4 deg.C/s www..com Temp. (deg.C) Time(s) Recommended condition Peak Temp. (deg.C) (1)In case of reflow soldering,please measure actual temp. on the product surface and observe recommended condition described left. (2)In case of exceeding recommended condition, please consult with us before use. (3)The temp. strongly depends on measuring method of profile, please note how to do it. (4)In case that temp.changes by PWB size, mounting density and so on, please check them by each PWB. Time(s)(200 deg.C or more) Manual Soldering Soldering Notes (1) Soldering Notes (2) When manual soldering, please observe below condition. Soldering iron : 20 W maximum Soldering iron tip temperature : 280 deg.C maximum Soldering time : 3s maximum This trimmer potentiometer is available for reflow soldering and manual soldering only. Solder and flux dissipated on the surface of element and contactor cause fatal damage, therefore in case of making wash and rinse, please consult before use. (2)Design PCB When designing land pattern, please design it,in accordance with recommended land layout deseribed in this production specifications for information. (3)Mounting Notes Mounting top side pressure loaded on the trimmer potentiometer shall be 4.9 N maximum. Overload is afraid to cause fatal damage as transform or breakdown. Because the back center of potentiometer is 2 terminal and the same potential,be careful of the pattern design sufficiently. After solder ball or solder scrap may cause short between the land pattern, so please make enough insulation there. (4)Adjustment Notes Adjusting top side pressure loaded on the contactor shall be 4.9 N maximum. Overload is afraid to cause fatal damage as transform or breakdown of adjustment knob. In case that the moving contact is set near the border portion between electrically effective and non-effective range ,electrically non-effective and open range, be afraid to be deviation of setting value. So avoid the setting like this. (5)Lock paint Avoid applying any lockpaint otherwise intrusion or dissipation of the paint may cause contact dectect. In case of being subjected to apply it,please avoid using adhesives that may generate corrosive gas. part Name 3mm Square Trimmer Potentiometers Part No. EVM3ESX50B** Issue Drawing No. EVM3ESEXX Revisions X 6 Resistor Business Unit LCR Device Company Matsushita Electronic Components Co., Ltd. 9 3rd Angle System Dimensions in mm (not to scale) 4.2 Circuit Diagram Notes www..com (1)Power Rating The Maximum value of electric power which can continuously dissipated from all area of a resistive element at the rated ambient temperature. In general, rated power shall be registrated in accordance with size & kind of them. Please observe to use below rated power.Continuously dissipation is afraid to cause fatal damege, for example,deviation,firing,smoking. (2)Influence of ambient temperature Influence of ambient temperature can not be neglected for operating trim-pot in general case. Please comply with power derated curve,in case of using it under the condition of exceeding specified power rating. 4.3 Mounting Notes This trimmer potentiometer is not available for sealed type, so this is afraid to be influented fatally under the following conditions. (1)Corrosive gas atomosphere of Cl, H2S, NH3, N0X, S02 and so on. (2)Moisture atomosphere of waterdrop, dewdrop and so on. (3)Water,Salt,oil,chemicals,solvents and so on. (4)Atmosphere of direct solar radiation. 4.4 Storage Notes Storage under the following condition should be avoided. Be afraid to degrade some performances and soldering wettability. (1)Temperature:less than -10 deg.C and more than 40 deg.C. Relative humidity:more than 85 %. (2)Atmosphere of corrosive gas. (3)Long term storage of over 6 months after delivery. (4)Atmosphere of direct solar radiation. Please store the package without unsuitable load and stress. While remaining some product after opening the package, any countermeaure of shutting moisture gas and so on,should be done. 4.5 Application Notes for electric equipments and instruments Although enough care is taken to ensure trimmer potentiometer quality. As life-end breakage mode,some fatal trouble might generate,such as spec-out resistance change, short or open circuits, abnomally generated heat. So please review the affect of any single fault of a potentiometer in advance. (1)The product specification for information ensures the quality of pre-set potentiometers. For applying ,please should evaluate this product under the condition built in the appliances. (2)The troubles caused by applying this product under out-specification should not be warranbted. (3)When applying for high-excellent liabilty and security appliances,for example,traffic transportation equipments(train,auto vehicles,traffic-signal equipments),medical apparatus, aircraft, spacecraft,heating,firing,gas,rotating equipment,security equipment, atomic-power equipment, machine-tool,and so on. Please make enough considerations to design fail-safe circuit system for safety as followings. *To make a safety system by a protective circuit or a protective device. *To make a safety system by the redundant circuit so that the single fault of a trimmer potentiometer does not cause a dangerous situation. (4)In case of arising some questions on the safety of this product,please don't hesitate to contact with our company and further technical evaluation should be done.
