We currently bake plastic SMT parts in accordance with the IPC guidelines for moisture sensitive parts. Because we have double-sided boards that are subjected to either an aqueous or semi-aqueous cleaning process, we do a 24 hour bake at 125 deg. C

We have a line that is double sided reflow and reflow/wave depending on the product being manufactured. We asked Loctite if we could cure our chipbonders with the reflow profile to eliminate having to change oven profiles for each. They said we wou
