Pretty pleased with it. There are some problems, but nothing too show stopping that a rework of the board layout won't cure, except one, and that can be solved by manually retouching the board before etching.
Here is the board as printed.
- Tracks touching each other. Most of these can be solved by making sure the tracks are not so close on the board.
- I reran the print to deposit a second layer of ink, but the pen went dry, so scraped the first layer off. I will try to retouch these with the new pen I need to go and buy.
- The diagonal tracks seem the be drawn too thick. It needs further investigation
- The pads for the SO08 chips were drawn so that they touched, either I need a finer pen, or I need to retouch these manually.
Looking at the board as it printed I think I might be able to make the track widths slightly smaller, this would reduce the possibility of two tracks merging.
