Sr. Tech, As far as I’m aware, most if not all, manufactures of thermal profilers offer K type thermocouples as a standard for profiling in the electronics manufacturing industry. In my decades of experience in the reflow and wave solder industry, t

you're right for sure, but there is some brand like hakko i don't like them why ? because process and menus (controllers) doesn't really give a good result. For example fm206, hot air/desoldering/soldering station doesn't have the real tc. And a lot

Recently, we have been experimenting with the 1.8/2.5 nozzle to be able to solder leads that are near an SMD. This pcbs were not design for selective solder, so we are trying to work within this limitations. I found the 1.8 nozzle very hard to insta

A little confusion here. Are you running several boards in one pallet and the last boards are looking poor or is the issue getting worse as the day progresses (like as the pallets get warm)? - If it is the last boards in the pallet, then you may wan

we do that and there's a variation on the solder temp. sometimes around 10 degrees, we have 2 solder pallets that are run in intervals of roughly 3 1/2 minutes a part (the time that take the operator to put all 3 terminals in a 42 pcbs per board, and

I'm not sure what happened to my post, but we think to have got the situation under control. The solder joints on the boards looked terrible. I can only describe it as unburnt flux, maybe. (like if you took a spoonful of solder and sprayed flux direc

We have a 6622CC machine for SnPb boards. A few things you may want to try: - Solderability testing on the components/PCB. - If the fuse holders or copper in the board are sucking up all the heat, try increasing preheat. Some fluxes (like the WS f

I have seen a couple of references to Black Tar, Not Black Pad. Apparently, it occurs only on the solder side of PTH's after wave solder and primarily on the edges of the land. It is characterized by a black coloration (Not Ni corrosion?) and non-wet

Thanks for the input. I read that paper. I'm not convinced the Pb stabilizer and bath MTO's are a cause of the Black Tar defect. If that were the case, given the history of Pb stabilizers and ENIG, I would have thought that there would have been many

Hi, I've got a Microline 200TF - I guess it's a 1980's machine. It's gone pop and I cant fix it without a circuit diagram (there's several pcbs in it with a variety of relays, triacs and what-not). If anybody has a circuit or any othe rinfo on it I
