When sourcing a Feeder Calibration Jig, you must prioritize mechanical precision and compatibility. Ensure the jig supports your specific SMT machine brands (e.g., Yamaha, Juki, Panasonic, or Samsung). Key specs include a high-resolution CCD camera (at least 1080p) for pick-up point inspection, a precision linear scale with an accuracy of ±0.01mm, and a stable 12V/24V power supply to simulate machine signals. The frame should be made of industrial-grade aluminum or stainless steel to prevent thermal expansion from affecting calibration accuracy.
