15 d solder paste to obtain the best soldering performance we suggest the use of following solder paste alloy: lead free solder paste sn - bi sn - zn (bi) sn - ag - cu (recommended) solder paste with lead sn - pb - ag (sn60-pb40-a, sn63-pb37-a) washing basically, all plastic encapsuled compon- ents, irrespective of the brand cannot be considered as being hermetically sealed. they are therefore only suitable for industrial washing processes to a limited extent. during the washing process, washing agents can penetrate the interio r of the component by capillary action through microcracks which might have occured. this is dependent on a number of parameters e.g - washing agents - viscosity of the washing solvent - temperature/time of the washing process - mechanical washing aids such as ultrasonic water pressure rinsing and spraying pressure the type of washing agent to be used is largely specific to the individual user or is often laid down by the manufacturer of the washing equipment. the agressiveness of the washing agent to be used can thus only be judged in appropriate test series relating to each individual washing pro- cess. by and large, the basic rule is that the washing process should be carried out as gently as possible. drying during the washing process, aqueous solutions can penetrate the component. this can lead to changes in the electrical parameters. suitable drying measures should ensure that no residual moisture or traces of washing substances are left in the component. initial operation/calibration due to the stress which the components are subjected to during processing, rever- sible parameter changes occur in almost all electronic components. the capaci- tance recovery accuracy to be expected with careful processing is within a scope of ! d c/c ! 5 %. for the initial operation of the device a minimum storage time of t 24 hours is to be taken into account. with cali- brated devices or when the application is largely dependent on capacitance it is advisable to prolong the storage time to t 10 days in this way ageing effects of the capacitor structure can be anticipated. parameter changes due to processing are not to be expected after this period of time humidity protection bags taped wima smd capacitors are shipped in humidity protection bags according to jedec standard, level 1 (emi/static-shielding bags conforming to mil-b 81705, type 1, class 1). under controlled conditions the components can be stored two years and more in the originally sealed bag. opened packing units should be consumed instantly or resealed for specific storage under controlled conditions. reliability taking account of the manufacturers guidelines and compatible processing, the wima smd stand out for the same high quality and reliability as the analogous through-hole wima series. the technology of metallized film capacitors used e.g. in wima smd-pet achieves the best values for all fields of application. the expected value is about: 0 2 fit furthermore the production of all wima components is subject to the regulations laid down by iso 9001:2000 as well as the guidelines for component specifications set out by iec quality assessment system (iecq-cecc) for electronic components. electrical characteristics and fields of application basically the wima smd series have the same electrical characteristics as the ana- logous through-hole wima capacitors. compared to ceramic or tantalum dielectrics wima smd capacitors have a number of other outstanding qualities : favourable pulse rise time low esr low dielectric absorption available in high voltage series large capacitance spectrum stand up to high mechanical stress good long-term stability as regards technical performance as well as quality and reliability, the wima smd series offer the possibility to cover nearly all applications of conventionally through- hole film capacitors with smd components. furthermore, the wima smd series can now be used for all the demanding capacitor applications for which, in the past, the use of through-hole components was mandatory: measuring techniques oscillator circuits differentiating and integrating circuits a/d or d/a transformers sample and hold circuits automotive electronics with the wima smd programme avai- lable today, the major part of all plastic film capacitors can be replaced by wima smd components. the field of application ranges from standard coupling capacitors to use in switch-mode power supplies as filter or charging capacitors with high vol- tage and capacitance values, as well as in telecommunications e.g. the well-known telephone capacitor 1 m f/250vdc. 09.06
