Dave highlighted all the elements that must be considered to determine the optimal temperature and duration for a pre-rework PCBA bake process. As far as the component is concerned, it really depends if you care about not damaging the package for r

Probably need more info on the PCB and why baking before reflow processing is part of your process, but if you're baking before reflow it makes sense you'd bake before rework. Is there a reason you don't AOI before wash?

Is there any technical reason why OSP finished PCB should not be baked? Your advice will be very much appreciated

3 more questions I promise. :) 1. If a populated PCB is put on a ESD safe Rack, is it able to be placed on a Plastic Shelf? 2. If a populated PCB is put in a covered ESD box, is it able to be placed on a Plastic Shelf? 3. Could we put ESD vinyl

Thanks for the tips... found out the ex-employee guy, had pre-bake conditioning put into the process flow, as this pcb is made of polymide material, that is reputed to have historical patterns in thermal sensitivity. To avoid "thermal damaging" the

Hi, Can anyone help explain the benefits/disadvantages of bareboard pcb baking, as part of the pre-heat conditioning, before the bareboard pcb use in SMT production run? The pcb board is 200mm x 240mm panelized pcb board, and has 28 smaller pcb boa

Larry, You can try one of two approaches, a bake above 100C will drive off moisture or use a vacuum bake. The vacuum bake process is slow since there is less/no air to conduct the heat. In the hybrid industry the standard vacuum bake was 16 hours at

We used to bake [100*C for 6 hours] all of our boards, but no longer bake at all. Before going off, your bake recipe is probaly OK. If anything, it's probably too short. Consider measuring the weight of wet boards, baking for a time, measure, bake
