Fortex 305 Operating Instructions Manual

PHOTOPOLYMER DRY FILM LAMINATOR
OPERATING INSTRUCTIONS

WORK ROOM LIGHTING

Room lighting is most important and Philips TL 65 W 16 striplights are suitable for room lighting as their
spectrum has no effect on most photoresists. Windows should be covered with non – bleaching yellow foil
which cuts out light wavelengths under 450 nm., yellow foil can be obtained from the Kodak company and
Plexiglas type " YELLOW 303 " is equally suitable. Processing should be carried out under dust free
conditions, the laminated and exposed parts must also be stored in yellow light until used.

THE LAMINATOR

The laminator uses two rolls of Photo-resist, and only two rolls of the same width can be used up to 305 mm in
width for the MODEL 305 and 610 mm for the MODEL 610. The dry film photo emulsion is sandwiched
between a polyester cover sheet and a peelable polyofin sheet. The laminator removes the polyofin cover sheet
before the film contacts the heated rollers; these rollers then fuse with heat and pressure the photo emulsion on
to the material both sides. On exit the rear cold pressure rollers continue to roll and fix the photo emulsion
onto the material.
