Gerber data is the industry standard format for providing data to PCBA manufacturers, fab houses, etc. when dealing with printed circuit boards. But, did you know it goes way beyond that?
I deal with PCB based RS274 Gerber data pretty much on a daily basis and have so for the past 16 years. Whether I am reviewing a design for a customer, evaluating a design to determine process necessity, or just looking at the latest open source design posted on the internet. I understand the RS274 and 274X gerber formats well enough that I can view/edit gerber files in notepad to determine why some gerber files won't import properly into software that I use (such as GCPrevue or Aegis CircuitCAM). However, I never knew that there was a detailed history behind the Gerber format until I saw this article:
David Gerber recently wrote a book about his father, H. Joseph Gerber, the inventor of the gerber format. This is a good article and the book looks very interesting as well.
