What is PCB drilling?
PCB drilling is a step in the manufacturing process of printed circuit boards that involves creating tiny, precise holes in the board. These holes may serve two main purposes: allowing electronic components to be mounted and establishing electrical connections between the different layers of the board. The precision required in drilling these holes is extremely high because even a small misalignment or size error can lead to malfunction, poor conductivity, or failed component mounting. Whether it is a simple double-sided board or a complex high-density interconnect (HDI) board, drilling forms the backbone of interlayer connectivity.
There are several processes used for PCB drilling, each chosen based on the board’s design and application needs. Mechanical drilling is the most common method and by far the most cost-effective, particularly with through-holes, while laser drilling is done to create microvias that are very small, used in HDI boards for compact devices like smartphones, computer parts, etc. Automated CNC drilling equipment is commonly employed for the drilling process due to their super-fast, repeatable, and accurate drilling capabilities and support for many different sizes of holes in a high-volume production.
