do you see signs of contamination or oxidation? if not why not just send them to the board house and have another OSP coating layer applied?

We are using OSP coated boards and no-clean solder paste. In a few instances, we are seeing increased distortion in an audio circuit. Has anybody seen or heard of surface insulation resistance (SIR) decreasing after reflow on OSP boards? Is it possib

We currently use a tool that we have developed and sell that can provide real time feed back on OSP coatings. With OSP it is a case by case basis on how many times you can reflow or apply heat before it becomes detrimental. Also, Depending on your pr

what type of solder paste are you using? Why the concern over wetting spread to the edge of pads? Are the solderjoints formed correctly at the component? Russ

Hi All, I work for a contract manufacturing and we are having a new PCB to build. The PCB has OSP coating on it and it has been sitting open in the production floor for about 15 days. I am not sure weather it will affect the soldering process or not

Dear Members, Sorry,I might have not made myself clear on this issue and creating some confusion.Actually the problem faced is during the DIP Soldering process whereby one of the connector(IDE Pin) solder is cracked and lifted from the pattern.Visual

Over the past several months we have experienced intermittent problems with wave solder voids on PCBs coated with OSP. We suspect variation in the OSP application process, or oxidation of the surface due to insufficient or degraded OSP. Is there a me

What are the handling requirments for PCB's coated with OSP? Also do most solder paste work the same with OSP or do I need to use a certain paste type?
