High quality dip coated positive working photoresist.
contains a dye which gives a good contrast against the copper, allowing boards to be easily
inspected at the developing stage. Panels are protected by a specially designed light-proof
blue film which allows them to be guillotined without the risk of fracturing the Photoresist.

U.V. EXPOSURE
Use a good quality artwork and purpose made U.V. exposure unit. The exact exposure time
will vary, depending on the quality of the artwork used and the size of the U.V. unit.
As a guide: Exposure times between 90 seconds and 120 seconds are normally sufficient.
DEVELOPING THE RESIST
Use 3204996 Developer concentrate. Mix as instructed and use between 18ºC – 24ºC,
preferably in a heated Processing Tank (157363). Developing time will depend on artwork,
exposure and developer temperature, 30 seconds to 180 seconds is typical.
Ready to use 141-310 Developer can also be used with this board, but the above mentioned
3204996 is recommended as the preferred developer.
