Homebrew PCBs

do you mean on polyimide kapton copper clad laminate??

you can get it on ebay ...

Actually thats not a bad idea ....

then run through a laser printer a few times .....  then etch ....

Heck ....

Spendy stuff though ..... but then agin .. its cheeaper than 200$ for a 3 board run ...

Subject: [Homebrew_PCBs] New PCB etching method proposal
















 



  


    
      
      
      I just had an idea of a better PCB generation system. It is still in the 

works, but may be a great solution.



There is the photo-resist method that needs darkness.



There is the Toner Transfer System that I use a lot. But I find that I 

am always touching up traces, especially the fine ones.



One person figured if they can print directly to the PCB using a laser 

jet, but the stiff board would not go through the rollers.



What if I can come up with a flexible material that can be printed to 

directly a positive image and then etch? It would be able to go through 

laser printers without a problem.



I am building up some samples to test, but would this list be interested 

in such a product?



Oh, to stiffen up, just add a piece of fiberglass to the back. Which I 

can make as well. Would you be interested in this method? How much would 

one be willing to pay for the materials for a 2"x2" size of board - 

granted a larger one would be possible as well. In fact, using a legal 

size copier would allow one to print up a 11" x 17" circuit board.
