Printed Circuit Milling Facility

A facility to manufacture prototype printed circuit boards is essential for an electronics school, both for research and for student projects.

In the past many departments have used a wet etching process, whereby unwanted areas of copper are etched away by corrosive chemicals. This is the same process used for mass production, as it is relatively quick. However, it is also environmentally undesirable.

The method currently employed by our School uses a computer controlled milling machine, which creates isolation channels around tracks and devices. Larger areas of copper can also be removed to give a traditional look by using the appropriate tools.

The milling machine also has the advantage of being able to drill multiple holes automatically, eliminating the lengthy process of drilling manually.
