Not to worry. Just run the boards through the cleaner. It will remove all the solder balls. The gross filter on your washer will collect all the solder balls. Coo eh? ;-)
How to cure SM? Is your mask UV, er thermal? After learning the type, you can begin to talk about the cure. Each mask supplier recommends the peculiars for its products. [I�d expect to cure SR1000 at 300�F for an hour.] Why do you want to do this? If it�s blanked, get your fab to fix it.
Testing SM cure? Look at: TM-650, 2.3.23 Cure Solder Mask. Hey, ask your fabs to check the cure. They�ll have the stuff.
Lemme guess. What are the odds that your fabs are both: * Using the same solder mask? * Curing it improperly?
Nada, zip, goose egg, etc. {Yeth!!! He shoots. He scores.]
Listen. Most often, bare circuit boards see some harsh processes (ie, HASL, ENIG, OSP, etc.) in the board shop after the solder mask is cured. If the mask survives these processes without any degradation, lifting, adhesion loss, blistering, etc., then you can probably assume that mask has been cured properly.
As Britney Spears says: �It�s you!!!!� Just think about the things that are consistent. Your: * Process materials. * Wave soldering process.
