Is baking PCB necessary before solder process?

Currently, we are baking any PCB before process on SMT, the 'reason' is to dry any possible humidity that could be inner the PCB, it does not matter if the PCB is multilayer or not. We bake PCB's at 107C for 4 hrs and the board must be process into n

Could be. It does indicate imperfection. * �The component was manufactured and shipped correctly and should not need baking in order to use it.� => Sounds good. Most classes of MSD packaging have a self-life. Lots of times it�s expired before it

We are going to be placing BGAs for the first time, and I have some questions. Is it recommended top bake all of the boards and all of the BGAs before production? I have had good luck baking boards that didn't wave solder well. It usually turns out

Do you buy in the PCB's from a manufacturer? If so, they may well offer such a service for you. We get quite a few different boards that come with either Kapton tape, or liquid masking already applied.

Hi, Our assembly process involves applying Kapton tape to the back side of our device, a laborious cutting and sticking operation. We are scaling up from "cottage industry" so I'm interested to know if you can buy Kapton shapes on a reel cut to our s

Probably, but the fabricator of these components can best respond to this question. The need to bake depends on the component design. J-STD-020 and J-STD-033 [as I recall] relate to moisture sensitive components and define 6 classes of moisture sen
