Using PCB Footprints

Creating PCB Footprints

This page is redundant!!! see pcb_tips. Furthermore, there is no better way to understand the inner workings of footprints than the pdf Footprint Creation for the Open-Source Layout Program “PCB”http://brorson.com/gEDA/land_patterns_20070818.pdf

Footprint basics

PCB Footprint FAQ

What is the Footprint naming Convention ?

Can I have two pads/pins with the same pin-number?

“Yes, totally. This is how you create oval shaped copper around pins, or funny shaped pads (e.g. square at one end and round at the other) by overlapping two or more pads."

How do I make an oval shaped pad around a footprint pin?

Simply add a pad on top of your pin and give them the same pin-number. If the soldermask is kept off both pins, and they overlap, they should appear as one pin on your board.

How do I make a 2-sided pad?

“Odd as it sounds, this can be necessary for some edge connectors. … but how do you do it???"

Edge Connectors

What are some references for making surface mount pads and footprints?

pcb_tips covers a lot of Footprint material. This page and that page need to be reconciled!
