... Before a solderability test is carried out, terminals are subjected to accelerated ageing (to IEC 60068-2-2, test Ba 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 ...

... General notes on soldering Permissible heat exposure loads on film capacitors are primarily characterized by the upper cate- gory temperature T . Long exposure to temperatures above this type-related temperature limit max 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 ...

... MKT, MKP, MFP (coated/boxed) 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. before they are subjected to subsequent electrical test- ing. Table A ...

... 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 ...
