0.25um(10u'') hard gold finger
0.8um(32u'') hard gold finger
1.0um(40u'') hard gold finger
Special : edge bevelling inside board.
Gold finger beveling
Bevel angle range: 20 °, 30 °, 45 °, tolerance + / 5 °.
Bevel depth:
Calculation formula of bevel depth：L=（D/2-T/2）/tgαα
D： thickness of board mm T: Residual thickness of board
α: bevel angle L: Depth of bevel mm
