ASSET InterTech published an ebook about the defects caused by process variances and how they can be detected with minimum effects on the manufacturing line. Manufacturing variances can degrade serdes performance and are all too common. Now embedded instrumentation offers a number of solutions for detecting process variances with minimal impact on product throughput. The title of the ebook is: How to avoid poor serdes performance caused by circuit board manufacturing variances.
The new e-book features a case study that analyzes the effects of manufacturing variances on a typical serdes trace on a PCB. A tool also included in the e-book can be used by engineers to calculate resistance and impedance on transmission lines.
Validating prototype circuit boards gives engineers a level of confidence, but variances in manufacturing processes are just as likely to erode that confidence right along with the transfer speeds on high-speed serdes traces. The book explains the many causes of process variations, their effects and, most importantly, what designers can do to detect variances before they take a costly toll.
