Questions of double Sided Pcb?
I have a few questions of manufacturing PCB two layers PCB: 1.Before printing, what should I do? Mirror the image of top layer? 2. How exactly do I make a via? 3. What's the best way to align the sides well for vias matching? 4.Is there some kind of coating that I can put over the board after soldering everything, so that a stray piece of metal falling on the board won't cause a short circuit?
I am heating the laminator as we speak and will post back with how it went shortly. I also ran the copper clad through the grinder on one end to give it a point. My hope is that it will fit tightly into the fold of the paper that way and not have the copper clad width to throw the layouts off.
I use the method that kl27x mentioned with the wire for vias. I cut it about an inch long and stick it through the hole.
