Finally got to test the double sided pcb widget feature designed by Ameen Nihad

Finally got to test the double sided pcb widget feature designed by @ameen.nihad ​. I would say it is a pretty good result considering its the first time using it. There is still quite some misalignment but it’s not too bad. I used 4 pin positioning in the corners and a 30deg v-bit for the traces ( waiting for a 0.3mm end mill to arrive). Thanks again to Ameen Nihad for this great feature.

Looks good, but yeah that misalignment is unfortunate. PCB factories do a lot of work to always ensure registration lines up.

Yeah i can see that being pretty hard to get 100% alignmed. I actually did another test on this same board and got much better results. I basically drilled the 4 reference pins and milled the traces for the top layer. I also drilled one hole on this side. After I turn the board around and positioned it with the pins. I then make sure that the hole drilled before alignes to where the same hole will be drilled and I make small adjustments if needed to the x and y coordinates.
