In regards to baking an assembly prior to hot air (BGA) rework.... 1) Do people always bake, sometimes or never? Does this depend on whether MS sensitive components are near the rework site? If a BGA is to be removed and reballed, baking is a no-br

I have a double sided PCBA setup. I have MSL components on both assembly sides. When I run Assy Side one I am within the allotted hours remaining on the MSL component. I then wait 40 hours before running 2nd Assy side. By then the hours on the 1s

I am currently working on a manufacturing flow where some PCBA are processed with reflow oven (after being baked before processing), then cleaned with bath, then passed into contaminometer, passed into AOI. The point is after all of this, if AOI dete

bake the pcba, continue with the aqueous cleaning but after the cleaning bake them in a circulated oven. we do that with some of our pcbs here we use a water base flux, we clean it and then we bake them for 10 minutes at 190F
