N.B.
The material to be laminated must be completely clean. PCB laminates
should be mechanically scrubbed clean with a Scouring pad or Scrub block.
Other metals should be cleaned by immersing in (500-172-2) 1320 Acid
Cleaner for 5 minutes at 40 – 45ºC or 7-8 minutes cold.

absolutely
essential
to achieve a good bond of dry film.
It is also very important to thoroughly wash the plate to ensure all scouring

running will give best results, and then thoroughly dry the material
