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

Hi I can't give you the answer for your question because I have too many questions and would have to know a lot more before I was comfortable giving any advice. I have done mass Baking of piles of PCB's as a needed evil when piles of boards were ex

Does anyone have any information on baking boards to remove moisture before reflowing and waving assemblies? I've been told that we should do this to stop such problems as delamination of boards, blow holes, solder balls, etc. I don't know have any e

Baking before assembly does nothing good. It: * Increases costs. * Adds steps to the process and makes scheduling more cumbersome. * Increases the amount corrosion on solderable surfaces. We used to bake to remove the moisture from boards that caus

Thanks for the advice. We have only done one PCB > with HMP solder and did not use preheating, but > I've been wondering if it would have been helpful > since we had some trouble getting the solder to > flow. If you have any more specific advice

Baking boards, especially multi layer, will help with blowholes and delimitation, but not with solder balls. Normally about 120c for 1 hour or so is sufficient. I usually will not go to this trouble unless a board has proven to be a problem or if th
