What is “gold finger PCB”? Someone will ask.

The “Gold finger” that we say is on theedge of PCB, they are always used for inserting this PCB into another installation as a connection.

They are always beproduced as “PCB gold finger chamfer”,the standard degree is 30 or 40.

In prototype PCB production, gold fingersare normally being produced without chamfer if the receiver doesn’t know what itis. Because for proto PCB order, ifyou need the chamfer and PCBs are not, you can mull by hand.

Volume PCBorder is always placed after prototypePCB order, so it is decided when the protoPCB used.
