    I'm in a process of making a presensitized PCB and soldering the components on by hand.

    When I did my first PCB's I used a 0.6mm isolate (spacing between ground plane and any other track/pad). Now I am using 0.4mm isolate and I'm considering 0.3mm isolate because it allows me to create a better ground plane (instead of having one looking like a fat U shape).

    Now the PCB mask will be professionally printed so printout quality won't be an issue, but before I try 0.3mm isolate, are there any factors I should consider first?

    I gave up making my own PCB a few years ago as I can get two layer boards with solder mask so cheap it just isn't worth it. Check This site for prices - example 100x100mm boards, ten for $17.

    In my project I plan to hire someone later on to make PCB's for me but to start with, I'm going to make my own because it takes less time than to hire someone to spend 3-4 weeks making one for me.

    When I've ordered boards in the past they've arrived in 1 week. Well worth the wait IMHO.

    Can anyone else recommend me a number (for isolate)? I don't know if 0.3mm is too low
