Abstract: A die detachment device for delaminating a die which is mounted at a position on an adhesive film comprises a plurality of movable plates having quadrilateral-shaped contact surfaces which are arranged adjacent to one another. The plurality of movable plates comprises an intermediate movable plate and outer movable plates on opposite sides of the intermediate movable plate. The contact surfaces of the movable plates together form a combined contact surface for supporting the adhesive film at the position of the die, each movable plate being movable relative to the other movable plates towards and away from the die.

Abstract: During detachment of a die from an adhesive tape, the inner and outer portions of a first side of the die which is in contact with the adhesive tape is supported with a support surface. A collet contacts the inner and outer portions of a second side of the die opposite to the first side. Support is withdrawn from the outer portion of the die such that the outer portion of the second side of the die bends away from the collet while the support surface only supports the inner portion of the die. Vacuum suction from the collet is applied to attract the outer portion of the die towards the collet and the vacuum suction pressure is monitored until a threshold pressure is reached indicating that the outer portion of the die is contacting the collet. Thereafter, the collet is lifted while holding the die with vacuum suction to completely separate the die from the adhesive tape.

Abstract: A frequency domain reflectometry-based bridged tap detection system for a telecommunication wireline employs a prescribed filtering operator, such as a ‘best-fit’ curve filter or a piecewise high pass filter bank, upstream of a Fourier processing operator, to improve the signal-to-noise ratio of the digitized amplitude array of the swept frequency band. To fit the response tones within the dynamic range of the analog-to-digital converter that digitizes the response tones detected from the wireline, a signal conditioning circuit, comprised of a comb filter bank, envelope detector and compander, is installed between the test head and the input to the analog-to-digital converter.

Abstract: A telephone test set is protected from an excessive current condition by a protection circuit that maintains sufficient loop current flow for continuous operation of the telephone equipment's functional circuitry, while by-passing and/or reducing excess current that could potentially damage the protected circuitry. A series current-limiting element is installed in the loop current path between a tip and ring interface and the circuitry of the telephone test set. A current shunting circuit is installed across the tip-ring ports of the protected circuit downstream of the current-limiting element. A current sense circuit monitors the loop current and controls the operation of the shunting circuit in accordance with the magnitude of the loop current. If a substantial overcurrent condition persists for an extended period of time, the resulting power dissipation associated with the high current flow will cause the current limiting element to change to a high impedance state.
