Include contact, termination, conductor and PCB-path tolerances, temperature and neighboring loaded contacts; then check each path against the exact applicable manufacturer documentation.",{"question":25,"answer":26,"answerText":26},"Is the cable shield the same as signal ground?","Not inherently. A shield, chassis and signal-return network can have different functions and may be connected differently according to the system design. Document their terminations and do not assume the shield supplies the intended signal or load return.",{"question":28,"answer":29,"answerText":29},"Does a passing continuity test approve the pinout?","No. It can confirm connections and reveal shorts, but it does not verify timing, impedance behavior, crosstalk, return-path continuity at fast edges or thermal performance. Use requirements-based analysis or measured verification of the actual interface where justified.",[31,32,33],"connector pinout","signal integrity","PCB design","high-speed-connector-pinout-return-path","en",[35,37,38,39,40,41],"de","it","cn","fr","ru",{"blog":43,"breadcrumb":52},{"@context":44,"@type":45,"headline":4,"description":5,"image":8,"url":46,"datePublished":6,"dateModified":6,"timeRequired":12,"keywords":47,"articleSection":7,"author":48,"publisher":51},"https://schema.org","BlogPosting","https://hilpcb.com/en/blog/high-speed-connector-pinout-return-path/","connector pinout, signal integrity, PCB design",{"@type":49,"name":50},"Organization","HILPCB",{"@type":49,"name":50},{"@context":44,"@type":53,"itemListElement":54},"BreadcrumbList",[55,60,64],{"@type":56,"position":57,"name":58,"item":59},"ListItem",1,"Home","https://hilpcb.com/",{"@type":56,"position":61,"name":62,"item":63},2,"Blog","https://hilpcb.com/en/blog/",{"@type":56,"position":65,"name":34,"item":46},3,1794758597598]
