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) B32932 ... b32936 ac applications (heavy duty series) / 305 v ac page 8 of 18 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 B32932 ... b32936 ac applications (heavy duty series) / 305 v ac page 10 of 18 please read cautions and warnings and important notes at the end of this document.
2 cleaning to determine whether the following solvents, often used to remove flux residues and other sub- stances, are suitable for the capacitors described, refer to the table below: type ethanol, isopropanol, n-propanol n-propanol-water mixtures, water with surface tension-reducing tensides (neutral) solvent from table a (see next page) solvent from table b (see next page) mkt (uncoated) suitable unsuitable in part suitable unsuitable mkt, mkp, mfp (coated/boxed) suitable suitable even when suitable solvents are used, a reversible change of the electrical characteristics may occur in uncoated capacitors immediately after they are washed. thus it is always recommended to dry the components (e.g. 4 h at 70 c) before they are subjected to subsequent electrical test- ing. table a manufacturers' designations for trifluoro-trichloro-ethane-based cleaning solvents (selection) trifluoro-trichloro- ethane mixtures of trifluoro-trichloro-ethane with ethanol and isopropanol manufacturer freon tf freon te 35; freon tp 35; freon tes du pont frigen 113 tr frigen 113 tr-e; frigen 113 tr-p; frigen tr-e 35 hoechst arklone p arklone a; arklone l; arklone k ici kaltron 113 mdr kaltron 113 mda; kaltron 113 mdi; kaltron 113 mdi 35 kali-chemie flugene 113 flugene 113 e; flugene 113 ipa rhone-progil table b (worldwide banned substances) manufacturers' designations for unsuitable cleaning solvents (selection) mixtures of chlorinated hydrocarbons and ketones with fluorated hydrocarbons manufacturer freon tmc; freon ta; freon tc du pont arklone e ici kaltron 113 mdd; kaltron 113 mdk kali-chemie flugene 113 cm rhone-progil B32932 ... b32936 ac applications (heavy duty series) / 305 v ac page 11 of 18 please read cautions and warnings and important notes at the end of this document.
3 embedding of capacitors in finished assemblies in many applications, finished circuit assemblies are embedded in plastic resins. in this case, both chemical and thermal influences of the embedding ("potting") and curing processes must be taken into account. our experience has shown that the following potting materials can be recommended: non-flexible epoxy resins with acid-anhydride hardeners; chemically inert, non-conducting fillers; maximum curing temperature of 100 c. caution: consult us first if you wish to embed uncoated types!

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" B32932 ... b32936 ac applications (heavy duty series) / 305 v ac page 13 of 18 please read cautions and warnings and important notes at the end of this document.
