RBP Chemical Corp., Milwaukee, Wis.
CleanerThe Sno-Gun II is said to remove particles as small as 0.1 μm, fingerprints and light oil from smooth, nonporous surfaces. This CO2 dry-ice-cleaning process reportedly does not scratch delicate surfaces found in semiconductor and optical industries.

Vapor Spreader Heat SinkIntended for use with microprocessors, RF transmitters and IGBT power semiconductors, the Therma-Base heat sink uses a two-phase heat-transfer process that reportedly alleviates thermal-spreading resistance. The base of the heat sink is a thin vacuum vessel, the inside walls of which are lined with a powder metal wick that is saturated with working fluid. As heat is applied to a portion of the base, the fluid at that location vaporizes, rushing to fill the vacuum. Wherever the vapor comes in contact with a cooler wall surface, it condenses, releasing its latent heat of vaporization. The condensed fluid returns to the heat source via capillary action, ready to vaporize again. The device is said to be smaller, lighter and to require less airflow than traditional heat sinks. Thermacore Inc., Lancaster, Pa.
