As a demonstration, the Ultrasound Research Group has created a prototype printer that can assemble a simple printed circuit board (PCB), and the company has produced a video that further explains this innovative technology.
The demonstration prototype employs an array of ultrasonic transducers for the positioning of electronic components on a PCB board. In order to ensure high positioning accuracy, it uses a camera for detecting the position of the PCB and the various electronic components. A laser is used for soldering the elements onto the PCB in a non-contact way, complementing the non-contact component manipulation.
