So how does this (lead free paste Sn42/Bi58) solder compare with the Sn-Ag-Cu (Tin-Silver-Copper) combination which does not flow as well (in the oven), needs higher oven temperature, (that can be adjusted by reducing the oven chain speed) and cost m

Kester is offering a tin/copper alloy for lead free. Any comments regarding using just tin/copper as opposed to tin/silver/copper or tin/nickel/copper? the price is low but why wouldn't everyone else offer just this alloy as opposed to the standard S

I did a post a while back about this with Selective. I don't recall all the details now, but you can search it.

I have the ability to offer both SAC and SN100C lead free alloys to my customer base. What might occur if a customer is already using SAC305 in their wave and they want to save money and go to SN100C. They now are mixing, tin,silver,copper with tin,c

Tin/Lead we have had no problem in masking off areas on a pcb during wave soldering. Lead Free alloys, Nickel Silver Copper would there be any compatability issues with a Peelable latex solder mask containing Ammonia. Really hot need to know.

SAC is a lead free alloy that comes from SnAgCu(tin, silver, copper). When you say SAC305 that means 3%Ag 0.5%Cu and the rest is Tin. About the LF I assume that it means Lead Free, but what metal contents it has I can only guess.

Lab tests can confirm the composition of your material. I'm going with tin oxide. Tin oxide changes color depending on the thickness of the deposit. Your deposit is fairly thin. It will change to a brown color as the thickness increases. Your EDX

Tin/silver/copper is the alloy I have done most with and it would seem that it will be the alloy of choice if you look at the people doing the work. There are still some issues of fillet lifting which I have seen on PIHR soldering and the same in wav
