- They drill the holes, prepare the surfaces carefully, plate a very thin
- layer of copper on chemically, and then thicken it with an electroplating
- process. That's a one-sentence summary of a complex and tricky process.
- It is not practical as a do-it-yourself exercise, not if you want reliable
- results. Getting it to work dependably requires precise control of things
- like temperature and solution chemistry, which means spending several
- kilodollars on professional-grade equipment.
