Fortunately, this discrepancy can be resolved by a simple experiment. Fuse the
toner to the Cu-clad as you have in the past (where the traces merged) then try
rubbing them off under water and/or with various solvents. (Hint - start with
water, then water with soap, water with detergent, isopropanol, ethanol,
methanol, acetone, ... Test each solvent on areas that weren't affected by
previous solvents, and on virgin toner.)


Let us know the results.
Donald.
