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

In regards to baking an assembly prior to hot air (BGA) rework.... 1) Do people always bake, sometimes or never? Does this depend on whether MS sensitive components are near the rework site? If a BGA is to be removed and reballed, baking is a no-br

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

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

Greg, If you are having a problem, i would first check board manufacturers process. Also are they shipping boards to you in seal packages (a must if you are in a humid part of the country.) Most of the time with a few simple process controls moistur
