Abstract:

A method and apparatus for fabricating a thermoelectric device includes forming a matrix board (12) with an array of orifices (100) formed therein. A plurality of P-type thermoelements (96) are formed and then a vacuum chuck (92) is utilized to dispose alternating ones of the elements (96) into the alternating ones of the orifices (100). A plurality of N-type elements (108) is formed and a vacuum chuck (104) is utilized to dispose alternating ones of the elements (108) into the remaining orifices (100) of the matrix (12). This forms an assembled array (52). A plurality of conductive tabs (114) is placed onto the P-type elements (98) and N-type elements (108) by a vacuum chuck (116). A second set of conductive tabs (120) is disposed on the opposite side of the assembled array by a vacuum chuck (124). A solder flow oven (54) and a solder flow oven (76) are utilized to reflow the solder on the tabs between the two operations.
