HawkEye inspection and RTC (Rapid Transit Conveyor) technologies now provide 100% board verification at a cycle time of 4 sec.
HawkEye isolates faults through rapid good/bad verification instead of performing data-rich inspection during high-speed manufacturing. Can verify 100% of printed boards within the line beat rate by analyzing streamed images instead of successive still images. To quickly isolate bad boards, the system records pass/fail per board against preset thresholds instead of capturing quantitative data.
The speed at which boards can be delivered and removed from the printing phase is increased through RTC’s board handling technology. Instead of the traditional, slow, belt-type transport that relies on friction to move the board, RTC grips the board, adapts to its dimensions and transports it into printing position.
