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
| Bevelling of gold finger | |||

FAQ
Do you sell cheap FR-1, CEM-1 PCB?
Yes, we just offer single sided PCB made of FR-1 and CEM-1. We also use punching tool for the contour for the mass production.
