Nitrogen in Reflow is grossly over-rated...., in my opinion, and in the opinion of several very well known SMT Industry "God Fathers". Way too much $$$, for a slight increase in the process window. If you profile your oven specifically for your pr

I am sick of Kapton. We have varying levels of leftover residues on multiple brands and I'm done chasing this thing. We have tested some wave tapes that were total garbage in years past. Really don't want to go there. Peelable liquid masks - Who

I did not see the histogram image (didn't scroll down). My point about the flat metal surfaces is they should have a large white total under top-light with red filter. You should be able to distinguish between the two (fillets and no fillets). I k

I will mention purchasing the updated software with him but last time he looked into it he decided against it. So I was trying to see what we could with what we currently have. As for blue filtering, we don't have that that I've seen. Red or white

Most of the PTH components are manually inserted. Some are auto-placed by our UIC machine. The parts are preped before install, so there is no need to trim the leads afterwards. The boards go through wave solder. The UIC machine has a clincher on

I like my JBC. I don't like the price of the tips, especially when you need 2 for the tweezers. The tips last a long time though. At one point JBC had a problem with the tweezer tips dieing early, but they appear to have fixed that problem. I also h
