Purpose:
Precision for printed circuit boards replication backsheet
ADT D (glossy)
Smooth, amber, high contrast, micro surface resistance of grain, suitable for high-resolution copy.
ADT C (Matte)
Semi-matte, amber, high contrast, the grain surface resistance. For fast vacuum, has the fastest operability.
Technical parameters:
· A high UV light shielding area density (D-max)> 4.7 *
· Exposure area of transparency (D-min) <0.15 *
· Strong chemical resistance and abrasion
High resolution
· Excellent dimensional stability
· Permanent antistatic
· PH balanced functionality with release paper
* X-Rite 369T usually measure the optical density was measured according to the following steps
Operation process:
1 stand: before the film 24 into the process chamber to accommodate at least the ambient tempera
ture and humidity, anti-ultraviolet radiation. Anti-chemical gases, especially ammonia,
Ammonia will film aging.
(2) Exposure: best exposure time varies due to the instrument. Recommended Stouffer 21 step scale to determine.
Correct exposure time: Exposure after the first and second order must be fully transparent
3 Developing: Carney Diazo film developing film completed by the diazo molecule. Many developing amm
oniated can get the best results, the film after development for at least a
Hours to achieve steady state
4 Storage: sealed in a dark film bag, should be stored at 15 ℃ -20 ℃, air-conditioned room.
