Your lack of obvious solder balls indicates you have a decent process. However, there are still small solder balls that are free and floating on the surface of the boards prior to wash. That same solder ball is washed off and ends up in the wash solu

For laminated FR4 PCB, we bake between 6 and 24 hours at 100�C. [Search for other bake recipes in the fine SMTnet Archives.] Alot of the determination of baking time is a function of: * Amount of moisture absorbed. * Amount of moisture you need to r

Dear Yukim, You may want to make sure that your presolder cleaning processes will support the change to a new flux. Many chemistries are vertically oriented and will clean only a selected few types of solder pastes. If you find that a new cleaning

Clearly someone from the equipment side will explain to me why this is an oversimplification, but what is the difference between providing support to the purchaser of second hand equipment and the guy that bought it new, assuming they're paying the s

Just a note about the EU and no-lead. Not all products are subject to the EU legislation on no-lead. I'm told its consumer electronics, PC, mobile telephones, telephones, games, automotive, etc... those that find themselves into the waste stream. And

Ok, maybe I'm missing something here: It's a no clean flux type AND your going to wash it? Why not migrate to OA Flux and just run DI water with Ion-Exchange beds? Benefits: No need for ultrasonics No need for chemical isolation No need for cleani

To be honest this product its only a part of bigger PCB, so we have only substrate with 3 FETs on it so no other components at substrate occurs and all substrate are staying at metal fixture. WE have already window pan aperture. WE producing this pro

No it is not any "western known" standard. Of course it is a binary type of data. But yes, it is possible to trace the RS232 data stream and interpret et the actual info. I know that this has been done before. You might want to just take a phone ca

At present, Infrared soldering technology became popular due to stream progress in the field of electronics. The stations become more popular among masters, engaged in repairing of composite printed-circuit boards, BGA reballing, soldering in hard-to
