Hi, Are you testing bare boards or soldered boards. Are the test probes in contact with soldered pads or contacting the copper with the osp coating (not soldered). If you could clarify this it would be easier to give some hints for probable causes.

Hi, I had the same question. In our case we are contacting the copper with the osp coating (not soldered). any published reports that we can reference Thanks

I am processing PCB's that have an n-tech osp coating and am finding huge inconsistencies in wetting. Some boards process clean with good wetting and the next has terrible wetting. The boards are stored and handled properly. Has anyone had this

Oxford Instruments makes a device called the OSPrey 800 that measures OSP thickness on the pads. We took a look at it last year because we have one line that uses OSP. It is pricey, and that's why we didn't order one, but if you use a lot of OSP, m

We are having problems with a specific lot of boards wave soldering. I need a way to prove the boards are bad, does anyone know a way to verify the amount of OSP coating on a board, or a company I can get to do it for me? I am using PBfree solder of

Jeremy, I'm gonna make a couple of assumptions by "reading in between the lines" of your email: 1. You're using no-clean paste. 2. This is only happening on the second side. You tell me if I'm wrong about this... First thing, if you're only experienc

Q1.Does anyone know a way to verify the amount of OSP coating on a board? A1. There is no specification. Thickness is difficult to measure. Thickness is product related. There are at least six major suppliers. Years ago, here on SMTnet, J Medernach s

Has anyone had experience in applying OSP coating? How difficult is the process? And, what is the equipment used?

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

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 ?
