Outside the MSD issues stated already (and I cannot provide a exact time not knowing multiple factors like Humidity levels, temps, exposure times, etc...) OSP might be the very worst finish to use in this scenario of side 1 / store on a shelf / side

Toluol (toluene). I use it in the solvent cups in my PVA machines to keep the nozzles wetted. We also use it to clean spots where coating is not supposed to be. Techspray 2510-N coating remover pen will also work very well for this.

Uresolve is the solvent I've used in the past but couldn't remember. Thanks!

You weren't specific about the OSP that you use. We use Entek Plus CU-106A. Yes, just about everything removes Entek, especially if there's heat involved. Ethone states: * Alcohol strips 70% of the coating * Water removes 15% * Kyzen Lonox only t

Good morning Jamie. I work at a CM and can offer some input on process flexability. I do not have any data on how reliable the coating is but I can say that they are both very difficult to control. Will you be selective coating or full coating? Ho

We too have recently got involved with conformal coating. We have had a good deal of sucess of cleaning the material off with gun wash. An aggessive solvent that does not harm the electronics and evaporates leaving no film

I looked at the tech data for the coating. It appears to need an explosion proof oven for curing (flammable vapors from solvent). I doubt the Heller reflow is explosion proof type oven.

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

I am going to be using a pressurized dispenser for Chemtronics CM1 peelable mask. I need to find a solvent that will work for flushing the system. I tried Xylene that we have here and it does ok, but not as good as I'd hoped. It works very well fo
