ABSTRACT:
An apparatus (10) and method for the automatic insertion of terminals (84) into cavities (16) of a ceramic substrate (15). A continuous carrier web (80) is advanced from a reel (90), into an automatic terminal insertion apparatus (10) simultaneously with the automatic advancement of substrates (15) along a trackway (20). As a substrate (15) is secured by a securement and lateral transmission apparatus (170) and moved laterally from the trackway (20) to align the substrate cavities (16) with associated transmittal barrels (162), a web hold down apparatus (130) secures web portion (82) of carrier web (80) and the cut-off blade (146) of a separation block (144) moves downwardly to separate a predetermined number of terminals (84) from the web portion (82) and locate the terminals in transmittal slots (152) located in a subjacent pressure pad (150). The separation block (144) and subjacent pressure pad (150) enclose the separated terminals (84) in transmittal slots (152) and move downwardly together to align the transmittal slots (152) with transmittal barrels (162). Compressed air is injected into the slots (152) and propels the terminals (84) through the slots (152) and aligned transmittal barrels (162) into the respective substrate cavities (16). The severed end of each terminal (84) bites into the respective cavity walls to securely anchor the terminals (84) in the substrate cavities (16), all without any swaging, scratching, marring, or damage to the exterior portions of the terminals. The exterior portion of each terminal is undamaged, has no cut marks, and plated terminals retain their protection against corrosion.
