The problem about covering it with glue (without using solder) is that the components might dislodge by a miniscule amount underneath the glue. So maybe the contact points will disconnect. I'm not sure if this will be a real problem, but if so it wo

Hi June, The biggest issue with an OSP finish is as soon as the PCB sees a heat cycle (reflow or wave) the finish will begin to degrade. If you have a single sided SMT assembly with THT components installed downstream it works pretty good. But a dou

I worked with a few BGA rework stations and also had the chance to see several demos on different brands. THe good ones that can really do it are equipped with camera, infrared under the board, different nozzles and a hot air comming from the head(di

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

We use both types in house. We started with a board moving over the pot, slowly moved on to Jade machines and eventually Synchrodex. Like you mentioned without palletizing you'll have component movements during the cylce and most likely won't have th

I can only say it looks okay for what you need, you will want a dual wave system it can make things so much easier. One thing to check would be the wave nozzle sizes I can see that the conveyor will do up to 15" but thats not to say the nozzle is
