Hi Chris, Yes there is a limit to the bake cycles : "...the cumulative bake time at a temperature greater than 90C and up to 125C shall not exceed 48 hours. If the bake temprature is not greater than 90C, there is no limit on bake time..." Ref: J-S

Hello, I have searched the forums for this specific topic, but can not find the clarification I would like. I am setting up a baking system to "reset" SMD components using a vacuum-bake oven. According to the JEDEC-STD-033 standard, depending on th

10% RH) Do these stored components need baking before I use them now or not? * Depends on the MSD level (should be marked on packaging) Level 6 component need to be baked prior to asembly no matter what. Other levels should be OK if they were store

Normally, you should not have to bake boards that are properly packaged and stored. Since you are seeing problems, baking makes sense. Consider 125C for 4 to 6 hours. Additionally, look here for more, while waiting for others: http://www.smtnet.

We have some larger MSL3 parts that require baking. they are 6mm thick which takes them off the chart provided at http://www.jedec.org/download/search/jstd033a.pdf Does anyone have a reference that would tell me the baking times for these component

We decided to bake components in tray package at 70 Degree prior soldering. I am looking for suggestion regarding baking time for MSL3 components: Up to 1.4mm package thickness 1.4-2 mm thickness 2-4.5 mm thickness In JEDEC-033B this temperature is n

I agree with Evtimov that sticking with the J-Std-033 is preferable to creating your own procedure at a different temp, especially if you need to pass an audit since the auditors will compare your process to the J-Std. My understanding is that oxida

Hi, can somebody please educate 1. What is the baking temperature and time before reworking a faulty board that is received from the field. 2. What specs that specifys this baking temp and time? Thanks

Dave i know abt the JEDEC033A specs..but this question is more of PCBA level. The baking temp and time at JEDEC is for MSD devices. I have tried to check IPC 7711 but the criteria does not mention the baking temp and time. Wandering is anyone is awar

First, reflow does not reset the clock for MSL exposure. The best solution is to run the second side before the exposure time expires. I am curious to know why they must sit for 40 hours. If that cannot be done, then store the assemblies in a dry c
