The complex history of PCB thickness
When we design a PCB we think of its final thickness (thickness) in discrete values: 0.2 mm, 0.8 mm, 1.55 mm, 2.4 mm and others. But.
Arc and twist of rigid PCBs
IPC-TM-650 defines arching and twisting as follows:
"Bow (Bow) (sheet, panel or printed board): The deviation from the flatness of a board characterized by a...
