Nextreme Thermal Solutions (Durham, NC) introduces an updated version of the OptoCooler HV14 that enables assembly temperatures as high as 320°C. The RoHS-compliant OptoCooler HV14 module is a high heat pumping thermoelectric device designed for standard electrical power requirements.
The new assembly temperatures make the HV14 compatible with eutectic gold-tin (AuSn) solder - the industry standard process for packaging optoelectronic devices that require tight tolerances. AuSn solder provides excellent joint strength, strain resistance, and thermal conductivity. Specific applications include laser diodes, semiconductor optical amplifiers, and sensors.
At 85°C, the HV14 operates at a maximum of 2.7V and can pump 1.7 watts of heat in a footprint of only 3mm². The module can create a temperature differential of up to 50°C between its hot and cold sides, making it suited for the cooling and temperature control of optoelectronic devices.
