The soldering iron tip temperature should besetat350°C(+10°Cmaximum)withthe soldering duration not to exceed more than 3 seconds.

This has increased the liquidus temperature from that of 183ºC for SnPb eutectic alloy to 217 – 221ºC for the new alloys. As a result, the heat stress to the components, even in wave soldering, has increased considerably due to higher pre-heat and wave temperatures. Polypropylene capacitors are especially sensitive to heat (the melting point of polypropylene is 160 – 170ºC). Wave soldering can be destructive, especially for mechanically small polypropylene capacitors (with lead spacing of 5 mm to 15 mm), andgreatcarehastobetakenduringsoldering.TherecommendedsolderprofilesfromKEMETshouldbeused.Pleaseconsult KEMET with any questions. In general, the wave soldering curve from IEC Publication 61760-1 Edition 2 serves as a solid guideline for successful soldering. Please see Figure 1. Reflowsolderingisnotrecommendedforthrough-holefilmcapacitors.Exposingcapacitorstoasolderingprofileinexcessofthe above the recommended limits may result to degradation or permanent damage to the capacitors. Do not place the polypropylene capacitor through an adhesive curing oven to cure resin for surface mount components. Insert through-holepartsafterthecuringofsurfacemountparts.ConsultKEMETtodiscusstheactualtemperatureprofileintheoven, if through-hole components must pass through the adhesive curing process. A maximum two soldering cycles is recommended. Please allow time for the capacitor surface temperature to return to a normal temperature before the second soldering cycle.
