Technical details and manufacturing context for Bond Head

Definition
The bond head is the critical component of a wire bonder responsible for executing the wire bonding process. It precisely positions and manipulates the bonding tool (capillary or wedge) to form electrical interconnections between semiconductor chips and their packages through thermosonic, thermocompression, or ultrasonic bonding techniques.
Working Principle
The bond head receives positional commands from the bonder's control system and uses precision motors (typically linear or rotary) to move the bonding tool to specific X, Y, and Z coordinates. It applies controlled force, ultrasonic energy (if applicable), and heat to form the first bond (on the chip pad) and second bond (on the package lead), while maintaining precise loop control between bonds.
Common Materials
Stainless steel, Ceramic, Tungsten carbide
