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 | |||
| a (°) | T (mm) | t (mm) | L (mm) |
| 20° | 1.6 | 0.50 | 1.51 |
| 2.0 | 0.65 | 1.85 | |
| 2.4 | 0.70 | 2.34 | |
| 30° | 1.6 | 0.50 | 0.95 |
| 2.0 | 0.65 | 1.16 | |
| 2.4 | 0.70 | 1.47 | |
| 45° | 1.6 | 0.50 | 0.50 |
| 2.0 | 0.65 | 0.65 | |
| 2.4 | 0.70 | 0.70 | |

FAQ
Do you sell high temperature PCB?
Yes. The material stability of high Tg (glass transition temperature) is high so that a high Tg PCB can be desirable. Multilayer and high layer PCB use this material much.
