Abstract:
Methods for making and using dissipative ceramic bonding tool tips (12) for wire bonding electrical connections to bonding pads on integrated circuit chips and packages. The method of using the dissipative ceramic bonding tool tip (12) includes dissipating charge while bonding to avoid damaging delicate electronic devices by a sudden surge of accumulated charge. The method of making the tool tip (12) includes affecting its conductivity so that it conducts electricity at a rate sufficient to prevent charge buildup, but not sufficient to overload the device being bonded. For best results, a resistance in the tip assembly itself should range from 5x10 (E)4 or 10 (E)5 to 10 (E)12 ohms. In addition, the tips (12) must also have specific mechanical properties to function satisfactorily.
Abstract:
A heater chip for thermocompression bonding, where the degree of heating at a thermocompression bonding part does not vary among individual heater chips and durability is enhanced. In a heater chip for thermocompression bonding, a small projection-like thermocompression bonding portion (2) heating up by conduction resistance is provided on a small plate-like body (1), on the head end side having a reduced width. A cut (3) is provided in the body, from the base end side toward the vicinity of the thermocompression bonding portion. Each of both sides of the cut serves as a conducting terminal portion (1a, 1b). A thermocouple (5) for temperature detection is installed in the vicinity of the thermocompression bonding portion (2). A projection portion (7) for thermo-welding a temperature detection portion of the thermocouple is provided on an inner side surface of the cut or on the outer peripheral side surface of the body.

Abstract:
A bonding tool (20) for bonding inner leads (58, 60, 62, 64) to semiconductor chips (50) is arranged to capture and align elongated lead sections (58, 60, 62, 64) extending in any one of plural direction, and preferably, in any one of two mutually orthogonal directions (26, 28). Thus, the tool (20) can be applied to align and bond all of the leads (58, 60, 62, 64) to a chip (50) without turning the tool (20) or the chip (50) even where the leads (58, 60, 62, 64) extend in multiple directions.

Abstract:
A bond head (10) is provided for a wire bonding machine having a linear axis frame (14), a rotary axis frame (16), a bond tool (11) and a wire clamp (52). The linear axis frame (14) is vertically linearly displaceable along a linear axis, while the rotary axis frame (16) is rotationally displaceable along a rotary axis. A pivotal connector (26) is provided which pivotally connects the rotary axis frame (16) to the linear axis frame (14), enabling the rotary axis frame (16) to rotate independent of linear displacement of the linear axis frame (14). The bond tool (11) is connected to the rotary axis frame (16) and is vertically linearly displaceable in response to vertical linear displacement of the linear axis frame (14) and rotationally displaceable in response to rotational displacement of the rotary axis frame (16). The wire clamp (52) is connected to the linear axis frame (14) and is vertically linearly displaceable in response to vertical linear displacement of the linear axis frame (14), while the wire clamp (52) is maintained rotationally stationary during rotational displacement of the rotary axis frame (16). The bond head (10) also includes a linear motion assembly and a rotary motion assembly. The linear motion assembly has a linear driver (70), a linear position detector (72) and a linear driver controlled (74). The rotary motion assembly correspondingly has a rotary driver (88), a rotary position detector (90) and a rotary driver controller (92).
Abstract:
A translation drive is disclosed for cutting pliers used in a wire bonder for mounting electronic components. The cutting pliers are secured in a slide guide and can move in the longitudinal direction of the bonding wire. The object of the invention is to provide a translation drive for cutting pliers used in a wire bonder for mounting electronic components in which the tail length and the cutting stroke can be adjusted at any time without problems by the control software of the wire bonder. The invention is characterised in that the cutting pliers (9) are driven and positioned in two directions from a zero position against the elastic force of leaf springs (3, 4) by means of a linear drive designed as a moving coil drive, a linear motor or a piezoelectric drive which is connected to the programming controller of the wire bonder and couples the moving elements of the slide guide to one another.
