Test Panels

Shown straight off the CNC router.  An example of a test pin panel having many tiny holes drill in the 5mm thick Fr4.

These tiny holes are drill in the the FR4.  In a 5mm panel we find we get around 40 holes before the tolerance is lost and the holes become under sized due to the wear in the drill bit.

For this project the Client sent us a sample of the po-go pins so that we could test fin the fins.

If you forward a design that requires something like this please also forward where you purchase your pins from and we will contact them to see if they also sell the corresponding drill bits.
