That's a Dexter product. Don't have the phone number handy but their corporate headquaters are located in Londonderry NH. They can get you a data sheet. The proper test method is similar to what you describe except that masking tape is not what's specified. Details on testing can be found in the IPC test methods manual. However, from the sound of things there definiely appears to be a problem. Most probable root cause (he said knowing long distance diagnosis is frequently bogus) is surface prep/cleanliness prior to mask application.

How about a test method for Solder Resist. On a recent trip North I have seen some circuit boards that are using this Solder resist and with a tape method of testing (meaning they put a piece of masking tape on the board and pull it up) they are pulling up the solder resist in some places. The copper is becoming exposed. Not good. If anyone has some information about why this is happening or where I can get a spec/data sheet on this material I would appreciate it.
