AC Line EMI Suppression and RC Networks – PME271Y A–E Series Metallized Impregnated Paper, Class Y2, 300 VAC

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

increasedꢀtheꢀliquidusꢀtemperatureꢀfromꢀthatꢀofꢀ183ºCꢀforꢀSnPbꢀeutecticꢀalloyꢀtoꢀ217ꢀ–ꢀ221ºCꢀforꢀtheꢀnewꢀalloys.ꢀAsꢀaꢀresult,ꢀtheꢀheatꢀstressꢀ

to the components, even in wave soldering, has increased considerably due to higher pre-heat and wave temperatures. Polypropylene

capacitorsꢀareꢀespeciallyꢀsensitiveꢀtoꢀheatꢀ(theꢀmeltingꢀpointꢀofꢀpolypropyleneꢀisꢀ160ꢀ–ꢀ170ºC).ꢀWaveꢀsolderingꢀcanꢀbeꢀdestructive,ꢀespeciallyꢀ

for mechanically small polypropylene capacitors (with lead spacing of 5 mm to 15 mm), and great care has to be taken during soldering. The

recommendedꢀsolderꢀproﬁlesꢀfromꢀKEMETꢀshouldꢀbeꢀused.ꢀPleaseꢀconsultꢀKEMETꢀwithꢀanyꢀquestions.ꢀInꢀgeneral,ꢀtheꢀwaveꢀsolderingꢀcurveꢀ

from IEC Publication 61760-1 Edition 2 serves as a solid guideline for successful soldering. Please see Figure 1.

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

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.
