Abstract:
A method of manufacturing a diode subassembly used in rectifiers of engine-driven generators, wherein the diode assembly includes a diode cup and semiconductor diode die and diode lead fitted therein, comprising the step of:positioning a diode cup within a diode boat having a plurality of soldering positions for holding diode cups therein; positioning a lead loader having a removable lead holder that holds diode leads therein over the diode boat such that the diode leads are aligned with respective diode cups; sliding the lead holder from the lead loader such that the diode leads fall into the diode cups which also have the semiconductor diode die positioned therein; inserting the diode boat within a furnace; soldering the semiconductor diode die and diode lead within the lower diode cup in an argon/hydrogen atmosphere of the furnace.
