We are considering storing OSP coated PCBs in nitrogen. Will this extend OSP life ? Is the eventual failure of OSP due to oxygen eventually reaching the copper over time ?

Hi Experts. We have an expired OSP pcb and we wanted to extend the shelp life. Is it possible to rework the PCB by removing the OSP coating, micro etching and re-applying OSP finish. Any advice if this can be done? Any solution for this OSP pcb e

Here are some options for removing OSP coatings from pads of the BGA substrates. * Leave the substrates in storage for 13-14 months. Shelf life of OSP coating is ~12 months, depending on the product. * Wash the substrates in your aqueous washer. Ea

Hello all, Can anyone know what influence has on RF/HF components when using PCB with OSP coating? We are now manufacturing our RF components on PCB with ENIG coating ,and want to use OSP instead. By the way:If anyone can send me an article on this s

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
