PCB drilling (which is also known as printed circuit board drilling), is the process of creating holes, slots and other cavities in an electronic circuit board.

During the PCB drilling process, a number of different hole types are drilled. These include via holes (such as thru-holes, buried holes, blind holes and micro-holes), component holes and mechanical holes.

Due to the precision required, holes are usually carved out using a manual or laser PCB drill. Boards can also be fed into a drilling rig manually or automatically. Here at ABL Circuits, our drill has a laser-detect function. This ensures both concentricity and correct bit diameter (0.1mm-6.5mm), even when unmanned.
