I want to build some short run kits and need some PCB boards. I can have them built by a local manufacturer or use a small CNC mill to construct them myself. What are the advantages and disadvantages of each method?

Etched pcbs are really cheap and the quantity you need could attract a decent discount. You also get silk screen printing and solder masking if you want them and, for any proper pcb I think this is essential.


An interesting post.

When mechanical milling removes the copper, it could affect the surface smoothness of the fiber glass /phenolic layer. This doesn't happen with etching.
