SO, can anyone quote the required wavelength of light required for some UV photo resists? The MG Chemicals exposure light is 375nm. I think it will do both their pre-coated positive resist boards and their negative dry film resist. Of course positive pre-sensitized boards are of no use to the laser plotting technique proposed.
