The current IPC/JEDEC standard J-STD-033 for moisture-sensitive devices does not include a bake cycle at 90C (it includes cycles at 40C and 125C for non-assembled components in reels or trays). However, the upcoming revision, which should be release

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

According to J-STD-033 Table 4-1, the bake out time to restore the clock to zero is not only determined by the MSL level, but the package thickness as well. Section 4.2.2 states "SMD packages shipped in low temperature carriers may not be baked in t

| 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

BOARD BAKING SCHEDULE: Bake time depends on the board thickness and construction. For laminated FR4 PCB, we bake between 6 and 24 hours at 100�C. ROOT CAUSE OF THE PROBLEM: Heating moisture entrapped between the laminations of the board too quickl

BGA Baking in Reels?

Electronics Forum | Fri Feb 01 16:14:55 EST 2008 | bghusker

We bake components in reels quite often using a low temp oven. If you look under JDEC standards they provide temps and baking times based off of the thickness of the part. The only problem with the low temp is that you could be looking at baking ti
