Dry film resist process
Webdry film wrinkles. by JEFFREY G. STARK and KARL H. DIETZ The dry film lamination process is designed to enhance uniform contact between the dry film resist and the sur-face of the PCB laminate material. The viscosity of the resist is lowered by the addition of heat transmitted through the rolls. The resist can then flow to conform WebQuite simply you cut your pieces of dry film to size as normal. Then submerge your copper clad in a tub of water. The water depth has to be sufficient to provide you enough room …
