Etching Circut Board Help Needed

John Board

Hi,

I'm running on a tight schedule (a few hours), and I've never done this before, can anyone give me some advice on etching a printed circut board? I've attached a design, could someone please look over it and make sure it is correct, and that I am not doing anything horribly wrong? This was designed as a "shield" for the Gadget Gangster Propeller Platform. Another question, can I make the tracks any smaller? My printer ain't too great, and I don't want some of the clooser tracks on the right touching.

Also, any good hints, or tips on etching a board? I.e., make sure you don't leave the board in the solution too long, or somethign like that? I've never done this before, and I need to get everything squared away in a few hours. Ohh, one more gremlin that I think I ought to mention... I only get one shot at this, if I get it wrong.....

Thanks,

John

P.S. I've also attached the source files in a "CorelDraw" format.

First thing is that you need to forget the 'I have only get shot at this' approach. Homemade boards are trial and error and practice.

Be sure to place a piece of glass over the art to hold it tightly against the board when exposing.

Be sure to not have on any clothes or shoes you care about.

G'day

Be sure to place a piece of glass over the art to hold it tightly against the board when exposing.

I'm using a "Print 'n' Peel" system, so, I print the design onto a piece of the substance, and then iron it onto the board, then etch it.

I'll see if I can do 2 practice boards first... Wish me luck!
