Do you mean that after/during development some of the exposed areas
(traces) are lifting off the board? If so, that is most likely down to...
1. Insufficient heat (and less likely, pressure) when bonding the
film to the board
2. Insufficiently clean board (finger oils, dust, oxidation..)
3. air bubble, or blister from too much heat
4. too strong/long developer
5. too short/uneven exposure
Here is a PDF with my current dry film tips:
