FIRST DOUBLE SIDED PCB
Here is my first double sided PCB … i tried something small. A adjustable Regulator for Micros… Uses a AMS1117 ADJ….
At first all my Double Sided tries failed due to no way to protect TOP SIDE from etchent. But after some thought and talk with the wife we tried… NAIL POLISH and it protects 100%
I am AMAZED! it worked so well. I took some pictures …
