Printed Wiring Board Definitions

A new page was added to cover Definitions related to PWBs. Most if not all of the terms were already listed within the Engineering Dictionary, but are now combined on one page.

I think the only incoming link is from the Electronic 'P' terms page, but I'll add more soon.
Oh, so this is the first up-load so some off the additions may look different because they come from different pages and of course some common terms may be missing. This page has been in the To-Do box for a few months, so no matter what it has to be a good start.

Up-date; I've added links to the PCB dictionary from the main PWB Information page, PCB External Trace Current Carrying Capacity, and PCB Internal Trace Current Carrying Capacity. A link also resides on the Definition of Minimum Annular Ring page.
