Plastic trays and other electronics component-transport mechanisms require an increasingly high degree of precision and uniformity in order to accommodate today’s smaller devices and high-precision automated handling systems. Flexible, feature-rich metrology systems now play a vital role in assuring the consistent dimensional quality needed in plastic tray component carriers. Some of the key metrology challenges in plastic tray inspection include versatile lighting and image processing capabilities that are critical for the accurate measurement of pocket positioning and interior pocket length, width, depth, and wall angles.
