Counterbore
The hole where the head of the fastener is partially or completely sunk into the PCB is called a Counterbore. The Counterbores of the PCB board are mainly used to fix the parts, and generally require screws. There are very strict requirements on the depth and size of the Counterbores on PCB, and its size must be limited within the tolerance range. Many factories can do this, but we can do a better job of controlling the accuracy of the hole depth by controlling the tolerance to ±0.2mm.
