mounting guidelines 1 soldering 1.1 solderability of leads the solderability of terminal leads is tested to iec 60068-2-20, test ta, method 1. before a solderability test is carried out, terminals are subjected to accelerated ageing (to iec 60068-2-2, test ba: 4 h exposure to dry heat at 155 c). since the ageing temperature is far higher than the upper category temperature of the capacitors, the terminal wires should be cut off from the capacitor before the ageing procedure to prevent the solderability being impaired by the products of any capacitor decomposition that might occur. solder bath temperature 235 5 c soldering time 2.0 0.5 s immersion depth 2.0 +0/ 0.5 mm from capacitor body or seating plane evaluation criteria: visual inspection wetting of wire surface by new solder 3 90%, free-flowing solder 1.2 resistance to soldering heat resistance to soldering heat is tested to iec 60068-2-20, test tb, method 1a. conditions: series solder bath temperature soldering time mkt boxed (except 2.5 6.5 7.2 mm) coated uncoated (lead spacing > 10 mm) 260 5 c 10 1 s mfp mkp (lead spacing > 7.5 mm) mkt boxed (case 2.5 6.5 7.2 mm) 5 1 s mkp mkt (lead spacing 7.5 mm) uncoated (lead spacing 10 mm) insulated (b32559) < 4 s recommended soldering profile for mkt uncoated (lead spacing 10 mm) and insulated (b32559) b32632 ... b32634 very high pulse (wound) page 19 of 27 please read cautions and warnings and important notes at the end of this document.

1.3 general notes on soldering permissible heat exposure loads on film capacitors are primarily characterized by the upper cate- gory temperature t max . long exposure to temperatures above this type-related temperature limit can lead to changes in the plastic dielectric and thus change irreversibly a capacitor's electrical characteristics. for short exposures (as in practical soldering processes) the heat load (and thus the possible effects on a capacitor) will also depend on other factors like: pre-heating temperature and time forced cooling immediately after soldering terminal characteristics: diameter, length, thermal resistance, special configurations (e.g. crimping) height of capacitor above solder bath shadowing by neighboring components additional heating due to heat dissipation by neighboring components use of solder-resist coatings the overheating associated with some of these factors can usually be reduced by suitable coun- termeasures. for example, if a pre-heating step cannot be avoided, an additional or reinforced cooling process may possibly have to be included. epcos recommends the following conditions: pre-heating with a maximum temperature of 110 c temperature inside the capacitor should not exceed the following limits: mkp/mfp 110 c mkt 160 c when smd components are used together with leaded ones, the leaded film capacitors should not pass into the smd adhesive curing oven. the leaded components should be assembled af- ter the smd curing step. leaded film capacitors are not suitable for reflow soldering. uncoated capacitors for uncoated mkt capacitors with lead spacings 10 mm (b32560/b32561) the following mea- sures are recommended: pre-heating to not more than 110 c in the preheater phase rapid cooling after soldering b32632 ... b32634 very high pulse (wound) page 21 of 27 please read cautions and warnings and important notes at the end of this document.
cautions and warnings do not exceed the upper category temperature (uct). do not apply any mechanical stress to the capacitor terminals. avoid any compressive, tensile or flexural stress. do not move the capacitor after it has been soldered to the pc board. do not pick up the pc board by the soldered capacitor. do not place the capacitor on a pc board whose pth hole spacing differs from the specified lead spacing. do not exceed the specified time or temperature limits during soldering. avoid external energy inputs, such as fire or electricity. avoid overload of the capacitors. the table below summarizes the safety instructions that must always be observed. a detailed de- scription can be found in the relevant sections of the chapters "general technical information" and "mounting guidelines". topic safety information reference chapter "general technical information" storage conditions make sure that capacitors are stored within the specified range of time, temperature and humidity conditions. 4.5 "storage conditions" flammability avoid external energy, such as fire or electricity (passive flammability), avoid overload of the capacitors (active flammability) and consider the flammability of materials. 5.3 "flammability" resistance to vibration do not exceed the tested ability to withstand vibration. the capacitors are tested to iec 60068-2-6. epcos offers film capacitors specially designed for operation under more severe vibration regimes such as those found in automotive applications. consult our catalog "film capacitors for automotive electronics". 5.2 "resistance to vibration" b32632 ... b32634 very high pulse (wound) page 22 of 27 please read cautions and warnings and important notes at the end of this document.
