TECHNICAL DATA /
PRINTED CIRCUIT BOARD FILM
KODAK PRECISION LINE Contact Film UCA7—High Complexity PCB Starts With the Right Phototools—
• Designed for making contact phototools from
photoplotter output or other line work.
• Negative working, slow speed, ultraviolet sensitivity
• Expose with high intensity metal halide or pulsed-xenon
source
• Use in white fluorescent illumination covered with
ultraviolet-absorbing material or in yellow fluorescent
illumination
• Very dimensionally stable ESTAR Thick Base with
antistatic properties under a wide range of humidity
conditions, both before and after processing.
• Excellent scratch and abrasion resistant overcoat.
• Produces high image density at line-for-line exposures
with minimum pinholes.
• Sufficient matte level on both sides to minimize
Newton's rings and to provide rapid drawdown in
vacuum printing frames.
• Can also be processed in a wide selection of machine
developers including lith and rapid-access, along with
KODAK ULTRALINE Developer and Replenisher.
SUPPORT
Dimensionally stable support.
7-mil (0.18 mm) ESTAR Thick Base
DARKROOM RECOMMENDATIONS
This film can be safely handled for up to a total of
60 minutes, before or after exposure, in up to 40 footcandles
(430 lux) of roomlight illumination substantially free of
ultraviolet (UV) energy. Such illumination is supplied by
yellow fluorescent lamps (warm white preferred) and white
fluorescent lamps covered by UV-absorbing or modified by
UV-absorbing plastic diffusers. Other roomlight sources
contain varying amounts of UV energy, and their roomlight
tolerances for this film should be tested under the specific
conditions of use.
STORAGE AND HANDLING
Keep unexposed film and processed film in a cool, dry place.
Process film as soon as possible after exposure.
EXPOSURE
Expose with a multi-level high-intensity metal-halide
exposure source. Optimum exposure should be determined
by means of a trial exposure series, following the equipment
manufacturer's recommended procedures. Use a trial
exposure time of 5to 20seconds at an exposure distance of
127 to 152 cm (36 to 60 inches). Contact your Kodak
representative for more information.
Note: Exposures for optimum line width reproduction are
critical when using a broad light source, and when making
base-to-emulsion exposures. Any light falloff from the
center to the edge of the exposing source may affect overall
reproduction quality and introduce problems with accurate
line-width reproductions.
Precautionary: Contact the manufacturer of high intensity
ultraviolet lamps for safety information pertaining to
ultraviolet radiation and ventilation requirements due to
ozone generation.
