Films We supply METODIAZ Diazo films D-18 in matted (M) and glossy (G) Version. The matting of type M offers a better and faster vacuum drawdown and eases the registration on liquid solder masks. The glossy version is optimised for exposing dry resist film and has a slightly better light transition in the clear areas. The colour of both types is a medium amber when exposed and developed (using ammonia steam developers). Upon request we can offer any other colour of diazo films.
METODIAZ D-18 diazo films are based on a 180 µm thick, dimensionally very stable polyester film, coated with a super dense diazo emulsion of coaters of latest technology. METODIAZ D-18 diazo films are manufactured especially for ASMETEC with a very dense diazo emulsion. Unlike silver halide films METODIAZ D-18 can be handled in room light for brief periods and is processed using ammonia vapours and moderate heat < 65 °C. METODIAZ D-18 do absorb little heat during exposing and imaging, thus remain sizes. METODIAZ D-18 is sensitive to UV/violet radiation (390 nm peak sensitivity). Mercury vapour lamps are typically used for exposure. A conventional diazo developer (e.g. ASMETEC TEM 22 WP) can be used for processingWe offer our customers a free of charge UV-density check of their film samples along with further technical comments in case the film samples show some deviations Download data sheet METODIAZ Diazo films Request
