Homebrew PCBs

Hey Guys, new here to the group and I love it.  

 

I've tried the Toner Transfer method a few times and wasn't happy with
the inconsistent results, so I tried the photo resist method. 

 

As the subject states, when I put my board in the positive developer
solution, of course it ate away the un protected  areas but also ate
away the circuit image as well. 

 

I'm using this developer:
http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1
&productId=156734&catalogId=10001&freeText=156734

And these boards:
https://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-
1&productId=156751

 

I've mixed roughly 1 part developer to 10 parts water.

 

I've exposed the board / image to a 125 Watt CFL for about 45 mins.  I
wouldn't think longer would hurt anything. 

 

Too strong of  a developer/water mixture ?  Did I keep the board in the
developer too long ? Any ideas  ?

 

 

 

 

 

 

 

 

Best Regards,

Steve Maroney
