A Guide to High-reliability PCBs from Design to Specification

Creating reliable PCBs is an outcome of considering all aspects that can affect reliability as early as possible in the design process. The further down the design process, the more expensive and risky it can be to fix. As they say, everything starts with the design. Because a good board design improves the reliability of the end product and lessens the risk of failure.
