IPC-SM-840. If overall thickness is not specified in purchasing documents, a supplier will do whatever it wants. Specify your requirements. Typical values are 20-50um. Regards

0.5 to 1 micron is typically too thick and can result in gold embrittlement of the solder joint. Typical IG thickness is 0.18 microns. see https://www.semlab.com/papers/gold-embrittlement-of-solder-joints/ Ed Hare

Hi, I have a general question about the relationship of PCB thickness and BLR testing result. For example, I have QFN6x6 parts mounted on board in 1.2mm, 1.6mm, and 2.4mm thickness. All boards have 6 layers of Cu. Studies show thicker board gives les

More detail Jinesh. Profile, datasheet of the part, stencil design, PCB finish, soldering material. Initially I am assuming you use pallet to reflow 0.2mm thick board.

Hi Chris, It's arround +/- 2MM. There was a gap if running pcb with thickness 1MM. The PCB position below the rail table.

Excuse me, but if I remember my physics lessons well, volume is what the water displacement measures, not mass. therefore, if you take the volume of water displaced by your populated PCB, divide it by the thickness of the PCB (which is easy to measur
