Pick and place system

A pick and place system is provided which connectable to an air and an electrical power source. The system has a pick and place unit Ä106Ü including an actuator Ä116Ü responsive to the connection to the air power source to move to a pick-up position. The actuator Ä116Ü moves a coupler Ä216Ü, which in turn moves a probe Ä222Ü to compliantly move to a pick-up position. The probe Ä222Ü is responsive to a connection to the air power source to pick up the micro device. A pneumatic valve Ä111Ü connected to the actuator Ä116Ü is capable of electrical actuation to connect the air power source to the actuator Ä116Ü and a supply valve Ä121Ü connected to the probe Ä222Ü is capable of electrical actuation to remove the power source from the probe Ä222Ü. Deactivation of the pneumatic valve Ä111Ü moves the actuator Ä116Ü and probe Ä222Ü to a raised position. A system control Ä104Ü, connectable to the electrical power source, is connected to the pneumatic and supply valves Ä111,121Ü for selectively, electrically actuating the pneumatic and supply valves Ä111,121Ü.
