- The saltwater etch process
- my own cutter etch process
- Take a piece of unetched PCB.
- Sit the IC (or an identical one) on the board and hold it in place with a crococlip, near a corner of the board.
- Mark on the PCB empty areas between pins using a permanent marker with 1mm tip. With a SOIC-8 you'll get 3 marks per side. The result:

- Remove the chip
- Very carefully with a cutter and a ruler draw connections between twin marks on each side of the IC, and extend them beyond your marks:

- With the cutter also etch a line across in the middle, so that you'll have 8 pads once...
- ...you cut the copper clad board with your favorite method so that the PCB is composed of 8 pads
- Check insulation between adjacent pads with an ohm-meter, "dig" more with the cutter if you measure zero ohms
- Pre-solder pads
That's it. Hopefully I'll add some pictures of the process.
