How to laminate the Dry Film Photoresist
1.
Cut a piece of dry film from the sheet or roll provided so that it is
about 4cms longer and 1 to 2cms wider then the material to be laminated
2.
Cut a piece of 200gsm paper or thin card so that it is bigger than the
film
3.
Using two pieces of adhesive tape e.g. Sellotape or masking tape,
place a piece of tape on either side of one corner of the film, so that they
stick to the film, but
not
to each other. Then pull the two pieces of tape
away from each other and one of the polyester protective films will come
away. (see figure 1 below).
4.
The material to be laminated must be completely clean. PCB laminates
should be mechanically
scrubbed clean with a (Mega part: 500-017) Scouring pad or (Mega part
900-009) Scrub Block. Other metals should be cleaned by immersing in
(Mega part: 500-172-2) 1320 Acid Cleaner for 7 – 8 Minutes cold or
5 Minutes at 40 – 45°C.
This is
absolutely
essential
to achieve a good bond of dry film.
5.
Remove the film completely, as well as the tape and having placed the
material to be laminated in the centre of the thick paper or card, lay the
film over the material with the side where the protective film has been
removed being placed in contact with the material. Then making sure that
the dry film is flat on the card at the side which will enter the laminator
first, tape this to the card. (see figure 2 below)
