8pins board lenght:63mm
CNC making pins
Pure cooper material, gold plated
the PCB is 2.0MM thickness FR-4 board, and with yellow soldering mask oil. Even if there is trace of rosin in the welding process, it is not easy to find.
The advantages of this turrets board:
1, The frame is installed on the fixing hole of the tube socket, and the distance between the pin and the tube socket can be installed with a 2W metal film resistor.
2, The width of the pins is the same as the width of the big 8pins tube socket. It is beautiful looking then.
3, There is a hole with a diameter of 1.2MM inside the pins for easy wiring.
4, There are shrapnels on the mounting feet, and there is little looseness when welding.
Size length: 4pins board 32.5mm, 6 pins board 48mm, 8pins board 63mm
