Formulated for outstanding performance on today’s newest dry film resists in spray or soak applications. ADF 25 breaks dry films into particles suitable for filtration. It also protects the panels from staining caused by dyes in the photoresist. ADF 25 demonstrates consistently high loading capabilities, and contains an enhanced copper brightening and antitarnish package. This enables it to produce a bright, uniform copper surface for automatic optical inspection and better etching characteristics.
