best method in circuitary...

[evilcow]

I hear stuff about "conductive pens" and "resist pens", what purpose do they exactly serve in a circuit? My goal is to allow certain solder "holes" to be connected through some sort of "lining" so the electrons can pass through. Where can i buy some of this stuff?
Like my book says.. use a resist pen, but the "resist" part got me worried. HELP!

edit: please make sure that whatever pen/material you suggest is solderable(<- did i spell that right? haw!)! :]

If the "resist pen" is what I think it is, it's completely different from "conductive pen".

Conductive pen is easy: it's a "pen" that contains some substance that conducts electricity. Draw a line on the circuit board between two points, the points are now electrically connected.

Resist pen (if it's what I'm thinking they mean) is very different. You must understand how simple circuit boards are made. They start out as boards completely covered with copper. The resist pen is used to draw the circuits (note: the resist pen material is not the conductor!). You take the copper board with the resist drawn on it, then place it in an etching chemical that eats away all the copper, EXCEPT the parts protected by the resist pen, leaving copper traces.

If you're etching a circuit board, you use a resist pen to draw the traces you want to make, then remove the exposed copper with a chemical. This produces your usual run-of-the-mill copper circuit board, extremely "solder-able".
If you're repairing a circuit board, you use a conductive pen. If for example you had a broken trace, you use the conductive pen to patch it. I don't know about the "solder-ablility" of that stuff, it's not really meant for making an entire circuit board.
