UV-curing System
The new aluminum I6P3 irradiator is a UV-curing system designed to eliminate the introduction of air and particulate matter into the process chamber. The microwave-powered UV lamps require air cooling to ensure operation and long life. Air is a simple option and is typically pulled or pushed via a blower through the lamp housing or irradiator. However, this cooling air can introduce particulate matter into the processing chamber, causing product defects. This product's irradiator with a custom light shield creates a curing system that addresses this problem by using a sealed air pathway. Fusion UV Systems Inc., Gaithersburg, Md.
Heat-pipe Assembly
|
ACK Technology has designed a new series of micro-heat pipes for power rating up to 45 W. These thin, flexible pipes reportedly can channel heat away from the hot spot in a tight place to locations of larger heat-dissipating surface. They reportedly can maintain a temperature difference of 10°C or less between the temperatures of hot spot and the cold end. The operating principle is based on the phase change of the working fluid inside the pipe. Fluid is vaporized at the hot end, flows to the cold end and then is condensed. ACK Technology Inc., Buena Park, Calif.
Pressure-sensitive Adhesives
ARclear optically clear pressure-sensitive adhesives, which are an alternative to liquid adhesives, are designed to offer high-performance, defect-free bonding technology that does not require curing.
