Is there any similar alternatives to this via pins ? Is there a general name for this kind of connector that I can google on?
Or probably there is a tool for producing this kind of tapered pins from a regular wire?

3\$\begingroup\$ Instead of trying to make vias yourself, I think many people today are preferring to just let a company like OSHPark handle their hobbyist-level designs, or a more professional firm for prototype boards/assembly. OSHPark produces VERY nice boards for little money. \$\endgroup\$– rdtscCommented Sep 27, 2015 at 14:47

1\$\begingroup\$ Sure, and basic shipping is free but can take anywhere from 3 days to 3 weeks. \$\endgroup\$– rdtscCommented Sep 27, 2015 at 20:27

1\$\begingroup\$ The cheapest I've found is $25 for a 5x5 board and I need 10x15 for my project and these are probably no less than a $100. If I was doing this professionally this would make sense but for a hobby project it's a lot of money for a board here. \$\endgroup\$– axkCommented Sep 28, 2015 at 12:40

Despite the attraction of getting boards done fairly cheaply, I still like to do things on stripboard and these "via pins" still have a use. Harwin don't do them any more, but Vero in the UK still do a lot of different pins at reasonable prices and have stock of most on 07 Nov 2015.
One of the uses I put them to, is mounting SMD's on the non-track side of a single sided board - very useful for things like PSU sockets that are sometimes only available in SMD form.
These are known as via or pcb Rivets. Some are hollow tubes, others are solid wire, and some are shaped. You can find them in a variety of finishes.
You probably won't find a tool to make cone shaped tapered ones like you pictured, but you can make simple ones with some wire and hammer. See: https://paulwanamaker.wordpress.com/300-2/ Standard riveting method applies here as it would armor or metal fabricated PC enclosures.
I have not tried this but if you put wire in a vice so that the tip of the wire pokes up about 1mm and then hit it with a hammer the top should flatten. Then just cut and repeat.
If you try this let me know how it works.
