Component Placement Verification on Printed Circuit Boards

In electronic component assembly, the measurement challenges associated with component placement verification are nearly as broad and diverse as the scope of electronic design and the types of components used. Key process control parameters that must be measured include the positioning and orientation (X, Y, and Z) of components relative to the substrate, as well as the detection of missing and/or damaged components. The wide range of sizes, shapes, and colors of electronic components further complicates measurement requirements, necessitating vision measurement equipment with highly versatile lighting configurations, powerful image processing capabilities, and a high degree of system programmability and flexibility. In certain measurement scenarios, vision measurement systems may also need to adapt to equipment such as automatic feeders or robotic arms and be integrated into a unified processing and inspection unit.
