As I mentioned in another thread I tried my hand for the first time at making my own PCB using the toner transfer technique. My first transfer didn’t come out very well and I’m getting ready to try it again, but after looking at the imprint on this board and I’m worried that the tracks may be too small for etching. Will the etching solution eat at the edges and undercut the tracks if it is too thin?
I made some the tracks a little larger in the software and had to move things around to allow more clearance, but I may run out of space on my 8x10 board. The PCB Artist program has the minim clearance set to 0.01” which seems way too small for etching, but then I’ve never done this before.
On my first try I used the default track width of 0.025” and I’m thinking of changing it to 0.08”.
This is a close up of just a small section of what I got for my first try with what needs to be fixed. So anyway I’m open to suggestions. Should I redo it with larger tracks and pads or just use a sharpie to fix it?
**broken link removed** I know the 8x10†board is too large for 1st time, but the expense of adding headers, connectors, and ribbon cable went outside my budget for this project. Also the addition of headers took up even more space. Anyway I found a neat idea of using a dowel for larger board at the pulsarProFx web site
