There 's one thing I'm not sure...For the OSP board finish whether we could bake and then store this kind of PCB?or whether once we opened the vacumm package of OSP board and then we can't bake it ? Thanks Bryan

First, what do you mean by "mishandled OSP" boards? Second, we don't like to bake our OSP boards, because of the potential to degrade the coating. Why do you want to bake these boards? Third, why not paste-up a board, reflow it, and assess the sol

Baking your boards will redue the amount of OSP on the board. If you use the boards quickly, you probably will not have a problem with baking [and don't bake too long]. Why do you want bake this board?

Is there any technical reason why OSP finished PCB should not be baked? Your advice will be very much appreciated

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

If you bake the boards at 125 degrees celcius for about 4 hours it should work. I would also suggest that you talk to the PCB supplier to take care of this baking for you. NOTE: PCB�s with an Entek or any other type of OSP finish should not be baked.

OSP has limited elevated temperature exposure capability. Couple that with the fact that solvents (IPA in particular) will remove the OSP. The more material you loose the higher the chances for pad oxidation. We ran an experiment with board washin

Moisture absorbtion in circuit boards

I think that the IPC spec only apply to the MSD. I had a paper from Lucent and forwarded by Francois Monette, please aware that the first 2 hours, the moisture doesn't bake out from the assembly/component and result show that it is increase the weigh

Methods that can reduce the wettability of OSP: * Previous heat cycles * Previous cleaning cycles * IPC-1601 "Printed Board Handling and Storage Guidelines" says do not bake prior to soldering * Using improper handling methods BR ... davef

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
