To All
 We are using RONASCREEN OPSR 5600 HARDENER & RONASCREEN 5600
OPSR 5600 CODE 2D-AU SOLDERMASK. The problem that we are having is after we
screen the board and tack cure the board at 160 F for 30 min. We then
expose the board then develop the board. Upon inspection of the board on
the developed areas we have found small little areas of soldermask all over
them if we try to develope them again they will not come off. Has anyone
come across this before if so, how did you fix it?
Last thing the the areas have Tin Lead on them.



THANK FOR ANY IMPUT
