Just throwing this idea out there - I am actually going to try it this week for a double sided LAYOUT
- print 4 images on the laser printer image 1=component side mirror image 2=solder side image 3=copper pour of the length of the board image 4=copper pour of the length of the board
- clean the double sided blank pcb
- use image 1 on one side and image 3 on the other side
- etch the board *** the result is that the component side is etched but the copper on the solder side is untouched
- drill out ALL HOLES
- use image 2 on the blank side and image 4 on the etched component side
- etch the board *** the result is that the solder side is etched but the copper side ( prviously etched but now covered with etch resist) is untouched
VIOLA double sided board - at the cost of more toner
Registeration should be near perfect as the suffering through "eyeballing" the images is dispensed with
A various of the above involves building the two sides on two single sided .032 or .024 boards and glueing them together ... I might try that in the future
what do you guys think about this?
