PCB knowledge: Edge connector(Gold finger)
In order to ease the insertion of the PCB into the receptacle, the edge along the connector should be chamfered or beveled. The beveling angle can be 20°, 30° and 45°, tolerance 5°.
 
Bevel depth (L)

Calculation Formula of Bevel Depth:
L= (D/2-T/2)*tg a
 

T: PCB thickness                  t: PCB remaining thickness
L: bevel depth                       a: bevel angle
 

FAQ
How do you pack the PCBs?
PCBs are packed with Polyethylene air cushion film(vacuum plastic bags) per 20-25 pieces. Pearl cotton (Polyethylene foamed sheet) are put inside carton box.
