Thanks for your help with this. I am new to the photoresist method of making my own pcbs and found that I ruined my first batch of 4 boards last night. First off I am using the Datak method with all their products to make them. After exposing the boards to the Datak Light for 12 minutes as instructed I placed them in the developer solution of the 10 to 1 mix. After
submerging the boards in the developer I could see the traces starting to appear after about 3 seconds. Within 5 to 6 seconds half the board traces were disolved and gone. What did I do wrong here? This was suppose to be easier and a better method than the transfer method. The Datak instructions only states to place the boards in the solution until the copper shows through. I think something has been left out. Any help would be appreciated.
