Speaking of PCB,<br>what is the finest pin pitch (or one can list pacakge)<br>that one has been able to sucessfully place and solder on a PCB<br>without resorting to a automated expensive sol'n but rather<br>a tech that is hobbyist based,
i.e. soldering iron, oven, etc?</blockquote><div><br>I've done SOIC with a hand-held iron. That's 0.05" pitch. Much more than one chip per board makes it trickier; the previous chip seems to block where the soldering iron needs to go for the next chip.

<br>so i am thinking of getting a home milling machine (modified roland)<br>that can do .01" traces and spaces, and assuming it does a good job,<br>then placement and soldering is my only worry.</blockquote><div><br>
0.01" traces and spaces are fun, but you'll want solder mask. Really. The combination of hand soldering small pitch devices and lack of solder mask is an unhappy recipe. <br><br>With a home made board you'll have more trouble with registration between sides and through hole connections than minimum trace width.
