I've had good and bad experiences with OSP's. First of all, ask yourself, "Why use an OSP?" If you don't need it, don't use it. Solderability is dependent upon the number of thermal passes (the fewer, the better), the thickness of the coating, the

Guys A very concerned engineer. Just been called over look at some PCB's in our diag area for missing components(0603).Too my shock I have just found that these components can be picked off just using a finger and applying some pressure. And apparen

guys Using a well estrablished water soluble solder paste, but having problems with tack time. Data sheet recommend a couple of hours but we are seeing problems after about 15 minutes with 0402/0603 componenets bouncing off. The printer environment

Thanx Dave, I agree with you on the planning part...yapp!! the same guy who've thrown an old datecode components to me..now they did it again on the PCB. Well Dave, could you explain a little bit more about the "hi-test flux" that you mentioned ab

We can offer two ways. We have a process control tool for OSP boards to validate the finish......but the dates yer talking may be best to take Daves F suggestion. NOW as far as the HASL finish goes...We may have your answer. We can Chemically revers

We currently use HASL on all of our boards and I would like to move to something else. I have sampled some boards with Entek OSP and I loved it, the problem is we have plated mounting holes on just about every board we make. Does anyone have inform

Hey all! The wave solder warrior is back. I have found a flux which leave almost no residue (the least yet), but because of its super low solids content I absolutely cannot get topside fillets. The multi-layer, two sided board is on a pallet w

| Okay, here's a stupid question. What exactly is HASL and OSP? We are going to delve into this technology where I work and I want to utilize the wealth of knowledge here to make life easier. Specifically, what are the differences, the advantages, di

Hi, I need help to understand further on the via in pad for 0402 requirement. If I were to do the DFM over the brd design which consist of 0402 with via on pad, what is the criteria that I should look for ? I learned that the via in pad does not wor
