Earl, et al, Boy things get old and cold around here fast. I promised more detail on my capactior problem and I thought I could drop something completely different in the same message and tell a tale of solder balls. First the caps. We still have

I don't know about potted PCBs, you'd have to talk to the recycle. My guess is it doesn't matter, worse case they just pay you a little less per weight so you'd just keep the potted PCBs separate from the rest of the waste.

Thinner: Flux thinner, NOT paint thinner We kept a spare stone in thinner in inventory. We cut PVC pipe to size, cap in one end, screw thread on the other, stone inside, filled with flux thinner and covered with a screw cap. I don't remember who we

for regular eutecticish solders, keep the pot temperature between 230�C [446�F] and 290�C [554�F]. If you polled us on our pot temperatures, we�d be all over the map, but with more lower than higher than you. High pot temperatures tend to generate

Anything with metal in it can be recycled; PCBs, wire, lead trimmings, used solder paste, etc. There are companies that specialize in this sort of waste. Typically they will provide you with containers and once you have enough waste, they will come p

Thank you all very much for the responses. The solder is eutectic and the problem, as far as I can tell, has been around before I was here, 2+ years. The flow machine is a treiber with 2 bottom preheaters and 1 top. The solder pot temp is 500F +/-4F

A couple of things that have helped me with solder ball issues at wave in the past: 1. Flux. Insure good flux coverage on the bottom of the board. 2. Preheat. Insure that the board is sufficiently preheated for the wave operation. Since you're

We haven't run a profile yet....probably because we're a-feared to. We can't do topside preheating here to any degree because we use an aluminum plate for aligning hundreds of top side through-hole components (pots, switches, buttons, LEDs) that te

We use nothing but silicones and have for at least the last 7 years. We don't have relays, but we do have motors. No issues with soldering, but our lines are constructed such that the last solder operation is a good distance from the coating or pot

My company is looking for a vacuum that can handle being used to clean up solder splashes on the bottom of our wave solder machines and around the solder pot area in our ERSA Selective Solder Machines. In the past we would use a Shopvac but these don
