Electronics Design Checklist C) 2003 Hank Wallace This a checklist for electronics designers. The idea is for engineers and technicians to share experiences and create a detailed checklist, which the individual designer can pare down to meet his or her specific needs. There are many details that go into the making of a first-run design success, and this checklist helps prevent Murphy s gremlins from marring an otherwise healthy design.-Electronics Design Checklist C) 2003 Hank Wallace This is a checklist for electronics designers.
