This short video is not a hobby board by the way. Another alternative is to use a prototype board house (search google for prototype pcb) these companies will combine projects from many customers to produce low qty boards. Often you can get a 2 layer board for about $35/ea. These boards will be plated like in this video (usually tin/lead solder not gold though)
Conductive holes in PCB's are typically an electro plating process. The process is not common for a hobby level PCB. For hobbyist, using a jumper wire, using surface mount parts, or existing leads of IC's resistors to connect one layer to another is more efficient.
I can't recommend a brand because I just grab the first one I see. It is conductive paint and non resistive. The one I used I think was called CRL but I'm not exactly sure. it has been awhile since I've worked on PCBs and I'm just getting back into it.
There is a very easy way to do this at home. Go to your local car parts store and buy the stuff to repair a rear window defroster. It is a liquid and conductive and when it dries it is durable.
This is a high resolution microscope's video. 99.999% of DYI don't have $ to buy or having access to this type of instrument. It's a PCB through hole all right, but it seems to be made by the normal plating process, not any technique doing at any home DIY.
I believe it looks like a coating of some kind, you can see how the copper sticks to the inner contour of the rough walls. I have this thing called 'copper spray' used on car head gaskets. I don't know if I should try that.

@ddzahn Interesting... Can you recommend me a brand name or something else Googlable?

How do they coat the inner wall with copper?
Thanks

it thinks it´s a ring they punch througth

why dosent you just use a jumper?
dumle29 2 years ago
I had been thinking of jumper wire too. But if I had 100 holes, it'll easier to dip it or spray it.

In industry, they dip whole array of circuit boards to solution and apply it by passive electrolysis or other chemical process.
