PS-28 Sub-Mounts

‣The package is flat, specialized for array detector applications.
‣The base material can be Kovar or cold rolled steel (CRS).
‣Gold or Nickel plating.
‣The number of pins is customized (usually 28 pins).
‣The package surface open for mounting is about 33 x 17 mm2.
‣Solutions with quite large powerful TE coolers are possible.
‣Array detector applications are involved

Single- and multistage thermoelectric coolers available for PS-28 header. Elongated shape provides a possibility to mount thermoelectric coolers with dimensions up 12.0x24.0mm2. This is a standard header for CCD matrixes.
