SN100C contains no phosphorus. It has a dross rate equal or lower than tin-lead solder, where as SAC drosses at 2 to 3 times the dross rate of tin-lead solder. Addition of solder dross inhibitors, such as phosphorus, can be effective inhibitors of

We treat all our alloys with measured Phos additions. SAC alloys treated with Phos WILL/DO dross approximately half the amount of 63/37. Most Solder companies will not tell you this as they wish you to use more Solder. We are a Nitrogen Cast Solder p

Hi, I have heard that some have added small amounts phosphorus to SAC alloy in wave soldering and this way decreased drossing. Does anyone experienced this with SN100C? Regards, Juha

Dear All Does anyone know about the low melting point solder paste which should be Copper Base? Usually the Copper base solder has 227'C of melting point.

Hi Patrick Noted that. Thanks for ur info.

Hi Mark thanks and useful. However, I couldn't find the Copper base solder paste which melting point is lower than 210'C.

Jacki, Lead-free Cu based alloys with melting point below 210C don’t exist.

I bet you that the problem comes from the ENIG brittle solder joints. About low temperatures I think you can go to the absolute 0 and the device should still work.
