Each terminal feeding unit (210) has a carrier cutting section for severing a terminal portion (BS) from a terminal belt (B), a crimping section (214) located at a pressing position (A), and a feeding section (215) for feeding a terminal (T) to the crimping section (214).

Abstract: The connector housings (1) to be fitted out are fed in succession along a feed track, and are then moved, by means of at least two grippers (19, 20), which are spaced apart in the advance direction and can be moved synchronously with one another, stepwise and individually in succession from a take-over position (FIG. 6b), along a connector housing guide and clamping track (12) into a fitting-out position (FIG. 6g, 6h), and are fitted out there with an electrical conductor, and are then moved by means of the respectively associated gripper along the guide and clamping track (12) into a release position (FIG. 6c).

Abstract: A conductive plug is formed in drilled-through vias of a printed circuit board of a polymer ink composition by a method of flooding the vias of a printed circuit board having parchment paper attached to an underside while the printed circuit board is on a vacuum table to form a first layer of the conductive plug within the vias. A second layer of the conductive plug within the via is formed by placing a stencil over the circuit board and flooding the holes of the stencil in order to form a second layer of the conductive plug within the vias of the printed circuit board.

Abstract: The wire handling apparatus of the present invention comprises a length measuring unit, a first clamp mechanism and a second clamp mechanism, a cutter mechanism, a first terminal pressing mechanism and a second terminal pressing mechanism, a first carrier mechanism and a second carrier mechanism, and a wire discharge mechanism, and synchronous moving means for upwardly/downwardly moving a receiving clamp part of the wire discharge mechanism in synchronization with upward/downward movement of a clamp part of the said second clamp mechanism in a terminal pressing operation of the said second terminal pressing mechanism is provided while the position of the said receiving clamp part is coincided with the position of a coated wire so that grasping of the coated wire by the receiving clamp part is enabled in the terminal pressing operation of the second terminal pressing mechanism.
