Homebrew PCBs

Can't seem to reply to the previous thread.

Sorry to see the stuff become unavailable!!!!  I ordered some off ebay about a year back and still have some. Did some test boards, seemed to work fairly well, was quite sensitive.  Worked well with my spin coater.  Been keeping it in the refrig in hopes of extending the shelf life.  In years past I used Shipley AZ111 and was able to keep that in the refrig for years past the expiration date.  Sure wish I could get the AZ111 again did a lot of boards with it.
