EEVBlog #543 – PCB VIA Current Investigation


Dave tests the myth that plugging a PCB VIA with solder does nothing (or not much) to improve the current handling capability. Is manual wire feed-through any better?
Does the industry rule of thumb of 0.5A per VIA have any basis?
What is the typical plated VIA/hole thickness?

Does a PCB VIA halve in resistance like a PCB trace does when coated with solder?
