Thanx for the feedback. The solder mask is PSR-4000 ( need to confirm this - not too sure ). If the board got in touch with the solder bath, for the contact time of 3 - 6 secs, this should not be the case for proper curing process right ?. thanx ag

I would assume we are talking about a radial leaded electrolytic cap? We use Electronic grade RTV (Dow corning 3145). It sticks good and can be removed if necessary. It is also pliable so you don't have to worry about CTE or other stresses that may

Hello all, We at SMTnet are ready to introduct a new and improved forum. I am sure all regular users will find it substantially more useful than its predecessor. The forum will be shutdown between 3 and 4 EST. Any messages submitted during that time

@ProcEng1 Yea. Mostly is ENIG surface finished PCB. Sometimes there is OSP board faces issues like part shortages and is forced to hold the production and resume the second process after a few days. So, would like to know any special control on keepi

Thanks Ken for your reply. Concerning OSP, there are a few negative points that I must considered for our application. I've read all the following points in an Entek document. Never test it. - If you have a miss print and you clean the PCB, the co

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 ?

You're correct. We prefer to probe solder, rather than copper, because the solder absorbs the impact of the probe better than copper and so, helps preserve the life of the probe. Beyond that, OSP has a limited "shelf life". If the OSP is not coate

Are you considering baking due to moisture exposure? Not all OSPs are created equal. I would check with your PWB fabricator about dry times and effects on their OSP finish. After you get it, I'd still try just one PWB for bake-dry out and check solde
