Subject: Re: [TN] Aspect Ratio&Area Ratio DefinesThomas,During the design of a PCB the total thickness will guide you as to what is the smallest size drill you can use to ensure that adequate plating is placed on the barrel of a PTH. This is the DOCUMENT that I have been searching for.ie ASPECT RATIO. If this guideline is violated there is a potential for LOW plating in the barrel. I recall the document. However I need to make a QUOTE to it. Therefore, I need to review the page and verse once again.victor,
