In our recent I-Connect007 survey, we asked the following question: “What is the most important feedback that you receive after your board is manufactured?” Here are just a few of the replies, edited slightly for clarity.
Jim Pierce, Axiom Electronics: "Impedance specifications, testing results, and documentation."
Jon Ashton, Vergent Products: "Insufficient copper clearances (pours, trace/space, etc.); items missed during quote that affect price; and Gerber-format array files for approval including drill and route info."
Roger Hughes, Blackmagic Design: "Design issues that have reduced fabrication yield and assembly yield, and therefore increased cost; and feedback that identifies areas of specific improvement."
