03082217 is a Valve Terminal Board for the vacuum system of the ASM SIPLACE CPP placement head. It is responsible for controlling the timing and operation of the various vacuum valves within the placement head.
Functional Overview
The vacuum system of the CPP placement head is divided into a pick/place circuit and a holding circuit. Serving as the electrical interface for the solenoid valves, the Valve Terminal Board triggers the vacuum valves for specific segments—in sequence—as the rotary turret approaches the pick position, ensuring that vacuum from the holding circuit reaches the nozzle. During the placement process, the system switches to a blow-off mode to release the component, after which the valves are closed to conserve compressed air. As the execution terminal for vacuum distribution logic, the reliability of this board directly impacts the component pick success rate and the rate of rejected components (mis-picks/dropped parts).
