Abstract
A bonding system includes a heating element, an actuator, an infrared camera, a pressure sensor and/or a displacement sensor, one or more processors, and a computer readable medium storing instructions that, when executed by the one or more processors, cause the bonding system to perform functions including providing a first control signal to a heating element, thereby heating a workpiece with electromagnetic radiation having one or more oscillation frequencies within a range of 1 MHz to 2.00 MHz. and providing a second control signal to an actuator, thereby applying a pressure to the workpiece via the actuator. The functions also include detecting a temperature of the workpiece, the pressure applied to the workpiece, and/or a displacement of the actuator, and adjusting the first control signal and/or the second control signal based on the temperature of the workpiece, the pressure applied to the workpiece, or the displacement of the actuator.
