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

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

| Does anybody have any reliable alternatives to device bake out for plastic bodied components. We do not use a whole package at time and therefore have to oven bake the balance before we can use them. | I have come accross dry nitrogen storage cham

Here is what you need to do if you can, Since you want to shporten the bake time you need to increase temp. weigh a board prior to your current bake process (you need very hi resolution scale for this) weigh the same board after current process a

Hi, I would appreciate some advice / recomendations regarding conditioning of PCB's before use. Our standard PCB's are double sided and rigid multilayer FR4. We are currently baking everything over 3 months old for 2 hours at 125 degrees C. Is thi

I may have asked this question before but couldn't find anything when I ran a search. Question, after ultrasonically cleaning our boards we bake them out to drive off residual moisture. Current requirement is 24 hours @ 105�C. I seem to remember a

Hi Oswald, Shelf life with ENIG if vacuum sealed and kept in controled enviroment would be 12 to 14 months. Shelf life in shrink wrap - No recomended packaging, 6 moths. If Shelf life goes over the 12 -14 months - Baking ? I would not suggest re-b

Mr. Wizard- Bingo, you did it again - don't know why I had to wait for the 3DBB before I saw the light. I have similar sitiaction to Steve - shake and bake, baby - two turns of the rotisserie- now ya got 2 bottles of californy spill on reserve - di

Need your opinion guys.. The old timers at the plant here feel that we should clean our board after Misprints withe the solvent cleaner over water wash. This is so they don't have to rebake the pcb for 24 hours before smt again. I don't believe th

Trapped moisture can be a problem, and one standard recommends baking a PCB for a minimum of 4 hours at 93+/- 5.5ºC before conformally coating. [NASA-STD-8739.1, “Workmanship Standard for Staking and Conformal Coating of Printed Wiring Boards and Ele
