PCB Circuit Board Reverse Engineering Old Library
The old libraries from PCB Circuit Board Reverse Engineering, or very old (pre-1.6) layout files may have incorrect pin numbering since there was no concept of pin numbers when they were created. Circuit card duplication uses the order of appearance...

Printed Wiring Board Reverse Engineering Element
Elements from Printed Wiring Board Reverse Engineering are supported by several special layers: silk, pins/pads and far-side. silk layer shows the package outline and also holds legend text and element names. The pins/pads layer is used to tog...

Elements of PCB Board Reverse Engineering
Elements from PCB Board Reverse Engineering represent the components on a board. Elements are loaded from ASCII coded files in a similar manner to the layout file itself, or from the library selector window. An element is composed of lines an...

PCB Board Reverse Engineering for Propagation Velocity Test Coupon General Guidelines
Measurement of velocity or propagation delay after PCB Board Reverse Engineering is generally more difficult than impedance measurements. For velocity the structure delay is determined by measuring the difference in time it takes the pulse to propag...
