i need a little cnc machine for fast prototyping pcb that contains TQFP 64 pin ic packages. can i achieve this resolution-precision with using gecko 203 drivers for 3 axis, 1.8 degree stepper, and proxxon mf70 ?
is there any good , low cost alternative? http://www.k2cnc.com/shop/proddetail...%2D2514&cat=26

how can i trust that specifications? and which one is more suitable because prices of them are close and k2cnc gives steppers.http://www.k2cnc.com/shop/proddetail...%2D2514&cat=26Originally Posted by rustamd
is gecko 203 right choice?
what is the most little milling-cutter pen? is 0.01 mm possible?
To a get a system that will hold .01mm you are going to spend alot more than any of the machines you are looking at
for example? how much money will be enought? and is there any example around , i wantto see it.
and how many mm can i hold with these (k2cnc machine) machines?
Holycnc,
The machines you mentioned might hold .025mm, I would look at a Minitech if you are serious about holding .01mm or better.

Also you might want to look at a NSK Astro Spindle Motor because the runout might be a problem otherwise.
Plan on spending about $12,500.00
Take care,

I have A360 (USB2.0) with camera (~9000$) - really good machine !
Example (produced with A360):
- TSSOP 38 pins with 8 mils pads and 7.5 mils insulation + full
copper rubout. Manufacturer states 4 mil traces, 4 mil insulation are OK.
