Soldering Process
The implementation of the RoHS directive has resulted in the selection of SnAuCu (SAC) alloys or SnCu alloys as primary solder. 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 – 15 mm), andgreatcaremustbetakenduringsoldering.TherecommendedsolderprofilesfromKEMETshouldbeused.ConsultKEMETwith any questions. In general, the wave soldering curve from IEC Publication 61760-1 Edition 2 serves as a solid guideline for successful soldering. See Figure 1.
Reflowsolderingisnotrecommendedforthrough-holefilmcapacitors.Exposingcapacitorstoasolderingprofileinexcessoftherecommended limits may result in degradation of 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-holepartsaftercuringthesurface-mountparts.ConsultKEMETtodiscusstheactualtemperatureprofileintheoven,ifthrough-hole components must pass through the adhesive curing process. A maximum of two soldering cycles is recommended. Allow time for the capacitor surface temperature to return to a normal temperature before the second soldering cycle.
Manual Soldering Recommendations
Following is the recommendation for manual soldering with a soldering iron.
Soldering iron tip temperature should be set at 350°C(+10°Cmaximum),withthesolderingduration not to exceed more than 3 seconds.
2. The maximum temperature measured inside the capacitor: set the temperature so that inside the element the maximum temperature is below the limit.

Polypropylene 110°C

Selective Soldering Recommendations
Selectivedipsolderingisavariationofreflowsoldering.Inthismethod,theprintedcircuitboardwiththrough-holecomponentstobesolderedispreheatedandtransportedoverthesolderbath,asinnormalflowsoldering,without touching the solder. When the board is over the bath, it is stopped. Pre-designed solder pots are lifted from the bath with molten solder, only at the places of the selected components, and pressed against the lower surface of the board to solder the components.
Thetemperatureprofileforselectivesolderingissimilartothedoublewaveflowsolderingoutlinedinthisdocument.However, instead of two baths, there is only one with a time from 3 to 10 seconds.
