Product Details

Detailed processing of PCB Gold Finger:

1) For PCB boards that need to be plugged in frequently, golden fingers generally need to be plated hard to increase the abrasion resistance of the golden finger.

2) Golden fingers need to fall backwards, generally 45 °, other angles such as 20 °, 30 °, etc. If there is no backward in the design, there is a problem. As shown in the figure below, the arrow shows 45 ° backward angle:

3) Golden fingers need to do a whole piece of welding windows. PIN does not need to open steel nets;

4) The minimum distance between Shenxi and Shenyin pads is 14 mil. It is recommended that the pads are more than 1mm from the finger position, including over -the -hole pads;

5) Do not apply copper on the surface of the golden finger.
