Thanks Cmiller & PR, I am warmed to hear others are doing this sort of thing.......like all inovative ideas, you often stumble into them. As far as im aware the ERSA dual Pot is the only machine avaiable on the market that can do this sort of thing

I have never seen excess tin [heard of it, just never seen it]. Excess lead yes, but tin no. See, tin oxidizes faster than lead. This means that dross has a higher tin content than the solder in the pot. So, with a very high dross machine, we regul

| Does anyone have any recommendations on spray fluxers? Are there major differences between the high priced ultrasonic machines to the low priced flux/air spraying machines? We are going to be spraying an OA flux with 11% solids content. Are there a

If what you are talking about is "assembly materials", then consider the following: - Solder paste - Wavesoldering fluxes - Bar (for filling wavesolder pots) - Underfill (for TCE-mismatched CSP's and flip-chip) - Cleaning fluids (for post-reflow boa

| What are the factors that go into determining PCB Board temperature requirements for the Wavesolder process? Most of the recipes I've seen call for preheating the PCB to around 230F - 250F. This temp is about 210F - 230F below the typical solder te

Welcome to RoHS. Or, at least, to the version of RoHS that I've had to deal with since I started with my current company. Blowholes and pinholes seem to be common in PB-free manufacturing. At least, they have for me here. I also note that IPC has

Hi All, We have been running a Novastar spartan 8S wave solder machine for a number of years. We actually do very little wave soldering and this machine has served us well. I have always been of the opinion that with the small pot and simple fluxe

I'm with John. Back in the old MIL-2000 days, the pot temperature was 245-275C (475-525F). Now, 240-260C (460-480 F) is more accepted for eutechic (eutechicish) solder. My2� Dave F

Kester has a special alloy for high temp soldering. Alloy 123. I would think that if you coocked 63/37 to 360c you would have a pot of dross in no time! Doug
