Soldering Process
The implementation of the RoHS Directive has required the selection
SnAuCu (SAC) alloys or SnCu alloys as primary solder. This has
increased the liquidus temperature from that of 183ºC for SnPb
eutectic alloy to 217ºC – 221ºC for the new alloys. As a result, the
heat stress to components, even in wave soldering, has increased
considerably due to higher pre-heat and wave temperatures.
Polypropylene capacitors are especially sensitive to heat (melting
point of polypropylene is 160ºC – 170ºC). Wave soldering can
be destructive especially for mechanically small polypropylene
capacitors and great care must be taken during soldering. The solder
profiles from KEMET are highly recommended. You may also refer
to the wave soldering curve from IEC Publication 61760–1 Edition 2.
Please consult KEMET with any questions.
