Drivers for PCB insertion loss - especially for viewers who do not have an electronics background
Polar presentation for the European Institute of Printed Circuits eipc.org Introduces the concept of insertion loss and which material characteristics have most impact. This webinar is aimed at professionals whose primary discipline is not electronics. So if you are a materials or process specialist - or simply interested in what causes signal loss on PCBs this presentation is for you.
This is an abstract from a longer webinar - please contact eipc.org if you wish more information from the other speakers referenced in this material.
