Hi Grant, I've seen a couple of good fluxes on lead free - WF-7742 from Indium & JS-EU-01 from Koki. I'm sure everyone else has a good one too - just make sure it is one formulated for the elevated temperatures involved. Cheers, Rob

There is one solder you guy want to consider, that is SCS7 from Asahi. It is Sn Cu & Si, and it is the lowest price at the moment. We had been changing our pot from SAC, then SACX, and recently to SCS7. The result is better than all other solders. I

Both SN100C and SAC305 are excellent and tested LF alloy formulations that with proper process management will produce good looking and reliable solder connections. "Bright & shiny" solder connections is NOT a good measure of a properly soldered LF c

Hi, does anyone have any experience with common wave soldering defects using SAC305 alloy?.....i am finding a lot of what seem to be shrinkage cracks on the bottom side surface of the soldered components.....there is also a lot of directional cooling

On a small, single stage RPS machine I was going through a dewar (not sure on the capacity differences between what you're using and a dewar) every 6-9 business days running normal 8 hours shifts. Side note, I'd suggest trying out SN100C alloy over

I am also getting ready to order solder for my new wave. Based on what I have read (here and other places) people prefer Sn100c for the wave. I have yet to hear of someone using Sn100c and switching to SACx. I am using SAC305 for reflow and I am tryi

SN100C, not as aggressive towards other metals as are other High tin lead free alloys. Why? Sn63/pb37 The lead prevented the tin from being very aggressive. SAC305 no lead, silver instead. Silver doesnt block Tin from it's aggresiveness. SN100C no si

the problem with using SAC305 is we have a very small window within which the connnector has to be removed.. otherwise Cu will dissolute. Now this process window is something between 20sec to 30 sec..depending at what temperature you are reworking th

CMiller, Thanks for the valuable info! We are in the midst of lead-free deployment and need to know good alloy choices at both wave and ERSA. I have heard the same things regarding SAC305's price for bar solder, but don't yet know what the process

We have been seeing continued difficulty with solder shorts and/or insufficient barrel fill with our Juki selective solder machine while using SAC305. We want to switch to something in the SN100 series, but we do not know enough to seperate the hype
