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.
