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

There 's one thing I'm not sure...For the OSP board finish whether we could bake and then store this kind of PCB?or whether once we opened the vacumm package of OSP board and then we can't bake it ? Thanks Bryan

Charly: Why do you "need to bake the PCb due to moisture issue", if you're not going to use the board? Why bake the board, just to put it back in storage, absorb moisture, and require baking again?

IPC-1601 covers PWB bake-out, methods for determining optimum bake time and temperature, caveats for certain PWB plating finishes, etc. IPC-1601 is to bare boards as J-STD-033 is to components

Dear experts, We are in stage to fix lapse or hold time between pre-bake to reflow process ( SMT ) for flex-rigid PCB, usually for flex pcb , we need to assemble as early as possible once after baking & if not , we can store in humidifier up to some

Claude is right, however, this may work: Dip the empty board in paint and let the access paint drip off. Measure the volume of the paint before and after. Dip a populated board and measure how much more paint was required in percent. Measure the surf

The Fancort flat racks are the most economical. That said, the problems encountered when populated boards are placed into the rack you can't utilize all slots. If populated to the edges you can't use at all. There are somewhat economical racks that a

Hello I want to aks more experienced SMT engineers about one thing related with Fuji machines. Is it possible to protect some how to avoid populating pcb with component from different batch? We have one same part number same vendor but customer does

This is easy experiment. Just run no populated PCB and that a populated one using the same spot for your thermo-couples. If you have a convection oven, you might be surprised how small this difference could be if not none. In some cases, I would expe
