NC drill equipment
NC drill equipment is driven by NC drill files. The automatic drilling equipment receives the NC drill files and performs a very high quality drilling of the PCB with extremely low errors.
The NC drill files are available for many types of numerical drilling machines in coordinates.
At single layer PCB, NC drill processing drilling must be done from the side covered with copper. The drilling design is EXCELLON and must contain inside a legend. The board file must be placed in the origin.
