Abstract
A pick and place system is provided which is connectable to an air and an electrical power source. The system has a pick and place unit including an actuator responsive to the connection to the air power source to move to a pick-up position. The actuator moves a coupler which in turn moves a probe to compliantly move to a pick-up position. The probe is responsive to a connection to the air power source to pick up the micro device. A pneumatic valve connected to the actuator is capable of electrical actuation to connect the air power source to the actuator and a supply valve connected to the probe is capable of electrical actuation to remove the power source from the probe. Deactivation of the pneumatic valve moves the actuator and probe to a raised position. A system control, connectable to the electrical power source, is connected to the pneumatic and supply valves for selectively, electrically actuating the pneumatic and supply valves.
