[Homebrew_PCBs] Quimical VIAs

2010-12-13 by Vicent Colomar Prats

Hi all,

Does anybody know or use an affordable and easy way, from the hobby (not
professional) point of view, to create doble-sided VIAs or Pads? I use the
technique of a thin wire sodded by both sides, but it's very slow and I
can't do it under soic or tqfp pakages nor in small diametres. I use double
sided pcbs with smd 0805, and very rarely 0603, components and soic and tqfp
ics. I would like to reduce size in pcbs, but it is mandatory, for that
goal, to use very small vias under ics, but I'm not able at the moment.

No matter if this is a technique, a comercial kit or a tool/machine. Also, I
can afford some hundred $$/�� in it if it is worth the job, but never go to
the thousand range. It is just hobby robotics what I do.

Greetings.
