In our website, documents and e-mail communication we use many technical terms as they are a part of the nature of our business. To simplify communication we also use abbreviations for many of these technical terms. Most of the technical terms and abbreviations are international standards in the Printed Circuit Board community. However to make it clear to everyone involved, we here present a list of technical terms and abbreviations used and their explanation. The order of items in this list is based on the order of their appearance in the Eurocircuits PCB calculator.
