System Design of a Thermal Control Unit for the Semiconductor Industry

System Design of a Thermal Control Unit for the Semiconductor IndustryCompass Manufacturing Services recently completed design and assembly of a thermal control unit for a customer in the semiconductor industry. This standalone radial jet thermal control unit delivers liquid to a heating and cooling system used during debug and failure analysis of microprocessors. The system required very specialized features and a software component, and had to meet a number of industry standards. It also required us to meet machinery, low voltage, and electromagnetic compatibility directives.

The steel-framed thermal control unit, which incorporated our hydraulic and control system design capabilities, measured 28" wide x 43" long x 67" high (excluding umbilical). Temperature control is maintained to ±1°C at ±.1 gpm. The mobile machine featured a 5 micron filtration, and UV sterilization of circulating fluid, a resin cartridge which produces moderately deionized water, and an umbilical connection to ancillary equipment. In addition this system also included Touch Panel PC with Windows 7 Software.

Upon completion of a prototype for this very detailed system, we performed factory acceptance testing (FAT) and third party safety analysis as well as a CE evaluation. To learn more about this project, see the table below or contact us directly.
