I am an EE graduate student interested in RF and hoping to learn more about high frequency PCB design.

(Posting here as instructed by email for free book on TL design).

Hello, I’m interested on several topics related to PCB manufacturing and assembly, mainly automatic testing of assembled boards. Any insights on low cost in circuit testers will be very useful as those machines used to cost millions of dollars and their accessibility was very limited.
