Dear all: In our product, the most large PCB is 500mm(long edge)*200mm(short edge). While short edge is holded, the largest distortion of the PCB would be about 1.2mm. In order to prevend the distortion, engineer should hold the PCB at the long edge. Now, we should add a symbol to indicate how to hold PCB. Is there any standard symbol? Any suggestion would be helpful.
