Product Specifications

Technical details and manufacturing context for Wire Spool & Feed Mechanism

Definition
The Wire Spool & Feed Mechanism is a critical component of a Wire Bonder that manages the wire supply. It consists of a spool that holds the bonding wire (typically gold, aluminum, or copper) and a feeding system that controls the precise delivery of wire to the bonding tool. This mechanism ensures consistent wire tension and smooth feeding during the thermosonic or ultrasonic bonding process used in semiconductor packaging and microelectronics assembly.
Working Principle
The mechanism operates by unwinding wire from a rotating spool through a series of guides and tensioners. A motorized or pneumatic feed system advances the wire in controlled increments to the bonding capillary or wedge tool. Tension control systems maintain optimal wire tautness to prevent slack or breakage during high-speed bonding operations.
