I have developed a method for easily and cheaply creating riveted Vias for circuit boards.
- A Via is a connection that goes from one side of a PCB to the other. There are times that you want to electrically or thermally connect the two sides of a board, and a regular commercial or soldered Via will not work – for instance a via in a home-made board may be under a chip and must be flush, or one is in a SMT pad and you don’t want the solder to wick down a via hole, or the via may need better thermal or current carrying capabilities. Here is the full article, now updated with more photos.
Update: I am building a test board with 100 vias in series, and a Themal Cycling Test Rig to determine if thermal cycling will cause failures in these kind of copper via rivets in FR4. See above.
