double side pcbs how to align
« on: March 02, 2008, 13:39:08 PM »
The question is simlple. How can i align good a double sided pcb?

What i do now is that i first stick the two slides together (front and back side) using a tape and i make something like an envelope that i pun inside the double sided pcb. But using this method i always have some misalignement, sometimes big and sometimes small.

There will be no problem. After all, you can as well drill outside the pcb. For example at the 4 corners of the board where you probably may have holes for screws...

Or also you can make the transparencies quite larger than the board and make some cross signs on both sides. There you can put a pin that will only wold the transparencies and not the board. I use this method and never miss a micro ;)

That would be also very nice and easy as long as the board is smaller than the transparency.
