PW Circuits can now produce burr free plated half hole / castellated PCBs. Old methods of routing away half the hole resulted in a burr remaining or the plating being ripped out of the hole, but with new processing stages this can now be achieved.  SMD modules like the Raspberry Pi Pico microcontroller board use this particular mounting style. These small modules are becoming more popular and are simple to work with so Contact us today for more information.
