Soldering Process

The implementation of the RoHS directive has resulted in the selection of SnAgCu (SAC) alloys or SnCu alloys as primary solder. This has

increasedtheliquidustemperaturefromthatof183ºCforSnPbeutecticalloyto217–221ºCforthenewalloys.Asaresult,theheatstress

Do not place the polypropylene capacitor through an adhesive curing oven to cure resin for surface mount components. Insert through-
