TH Components 113 ASSEMBLY RECOMMENDATIONS FOR TH COMPONENTS Very often before soldering through-hole components, their leads get bent. It is important not to damage the component during lead bending. Typical damage incurred during bending is cracks in epoxy parts, which can lead to increased humidity sensitivity of a component and consequentially to a shorter life time. In order to avoid epoxy parts damage it is necessary to: - fix the most sensitive point (epoxy parts) of a component body - bend the wire at least 2 mm below the end of epoxy parts Other potential damage to a component which can lead to component failure or a shorter life time is thermal shock during manual soldering with a soldering iron. This can occur in the case when a soldering iron is placed too close to one point of the component body and most often it happens if the solder joint is too close to the varistor body. Resistance to Soldering Heat In the case of automatic wave soldering, it is important to provide sufficient resistance to soldering heat. In order to prevent any potential problems VARICON decided to introduce their own internal standard for testing the resistance to soldering heat of through-hole components: 3 C, s. Pb-free Wave Soldering Profile Recommendations Recommended soldering profiles for all above components are in accordance with JEDEC standard curves (J-STD-2D) and therefore compatible with the new Pb-free process. lead-fee Wave Soldering Profile Pb-free wave soldering profile requirements for soldering heat resistance of components Parameters Symbol Specification preheating temparture gradient 4 C/s max.

This change is called ageing. If the capacitor is heated, for example during soldering, the capacitance value increases tohigher value and the aging process begins again. The level of de-ageing depends on temperature and duration of the heat - for example an almost complete deaging is achieved at C in one hour. These conditions are also the basis for reference measurements for any testing. Ageing constant is defined as capacitance change per time decade. Ageing constant differs for various types of ceramics. For 2E3 and 2F3 ceramics used for RFI suppression and safety capacitors ageing constant ranges from -3 to -5%.

98 Capacitors Term Symbol Definition Reference Measurements Soldering Specifications Climatic Category Storage Due to ageing it is necessary to quote an age for reference measurements which can be related to the capacitance with the fixed tolerance. As defined in CECC 37 this age is H. If the age of the capacitor is known, the capacitance for T= h can be calculated using known ageing constant: K= (C1-C2)/[C1*log t1/t2] => C2 = C1*[1-k/(*log(t1/t2))], where k is ageing constant in %, t1, t2 are measurement time points and C1, C2 capacitance values at time t1 and t2 respectively. It is important to de-age the capacitors before any stress testing, so that the changes as a result of the test are not affected by age. The following procedure should be used for any stress measurements (according to CECC 37, appendix B): - de-aging at C, 1h - storage: 24h at 2-25 C, 5-7 % RH - initial measurements - stress test - de-ageing at C - storage: 24h at 2-25 C, 5-7 % RH - final measurements Conditions Soldering Soldering Time Distance form Component Body Temperature Solder ability 25 ± 5 C 2 ±,5 s > 2 mm Resistance to Soldering Heat LCT/UCT/DHD 295 ± 5 C ± 1 s > 5 mm UCT = The maximum surface temperature for which the capacitor has been designed to operate continuously LCT = The minimum surface temperature for which the capacitor has been designed to operate continuously DHD = Dump Heat Test Duration Solder ability of leads is not affected by storage for 24 months, if storage temperature is -35 C and relative humidity up to 6%.
