Abstract: A terminal crimping device includes crimp tooling including an anvil and a ram movable toward the anvil with a crimp zone being defined between the anvil and the ram configured to receive a wire and a terminal configured to be crimped to the wire by the crimp tooling. An ultrasonic transducer is coupled to at least one of the anvil and the ram that receives acoustic signals sent through the wire and terminal. A crimp quality module receives signals from the ultrasonic transducer. The crimp quality module determines a crimp height of the terminal based on the acoustic signal received by the ultrasonic transducer. Optionally, the crimp height may be determined based upon a transmission time of the acoustic signal from a transmitting transducer to a receiving transducer. The crimp height may be determined based upon a speed of sound transmission coefficient of the terminal and the wire.

Abstract: A punch down insulation displacing connector housing is a body made of plastic which surrounds the connector. The housing restrains the connector parts from longitudinal movement when the connector is positioned to be press fit onto or to be soldered onto a substrate such as a printed circuit board.

This housing will stop movement of the connection tool head during wire insertion to position the wire inside the connector at a desired position. Also, the housing offers a surface where the connection tool head will stop and cut the wire. This housing is used on a compact electrical connector and will surround the connector. The housing can accept various types of connection tool head.

Abstract: A method for manufacturing an array of stacked capacitors having vertical sidewalls with increased capacitance on a dynamic random access memory (DRAM) device was achieved. The invention utilizes two masking steps and self-aligning etch back steps to form a very high density array of bottom capacitor (node) electrodes for a DRAM device. The method involves depositing and planarizing a thick first polysilicon layer over a partially completed DRAM cell. A silicon oxide layer with openings aligned over the node contact openings of the pass transistors (FETs) is formed. Silicon nitride sidewall spacers are formed in the oxide openings and a thermal oxide is grown on the first polysilicon layer. After selectively removing the nitride spacers the polysilicon is etched to form the inner sidewalls for the bottom electrode. The oxide etch mask layers are removed and a second photoresist mask is used to define the outer perimeter (sidewalls) of the array of bottom electrodes.
