A bonding apparatus includes a bond head structure, an optical unit and an actuator unit. The bond head structure includes a bond head collet, a connecting unit to which the bond head collet is attached and a look-through passage extending through the bond head collet and the connecting unit along a central axis of the bond head structure. In use, the bond head collet holds an electrical component to be bonded to a bonding area of a base member and the optical unit is positioned relative to the bond head structure to view and inspect the electrical component through the look-through passage of the bond head structure. The actuator unit moves the connecting unit of the bond head structure based on the inspection of the electrical component by the optical unit, to align the electrical component with the bonding area of the base member.

High precision bonding apparatus comprising heater

A bonding apparatus includes a holding element, holding element actuators, sensors, a controller and bond force adjusting actuators. In use, the holding element holds an electrical component and is moved by the holding element actuators in one or more actuating directions to contact the electrical component with a base member. The sensors measure reaction forces exerted on the holding element in response to contact between the electrical component and the base member. The controller determines bond forces to be exerted on actuating areas of the holding element during a bonding process based on the measured reaction forces, and the bond force adjusting actuators exert these bond forces on the actuating areas of the holding element during the bonding process, so as to adjust a tilt of the electrical component relative to the base member.
