[0002] One of the key processes in semiconductor packaging is center bonding, which is to bond the semiconductor photoelectric sensor to the substrate and achieve the center alignment requirement. The traditional center bonding process needs to be carried out under a microscope: first, apply adhesive to the substrate bonding position, then fix the substrate on the microscope stage, observe and manually adjust the sensor position to ensure that the sensor center is consistent with the substrate center, then press and fix the sensor and wait for the adhesive to cure. During the curing period, the sensor center cannot be moved to prevent the position of the sensor center from changing with the substrate center. As a result, the process takes a long time to wait for the adhesive to cure, resulting in low production efficiency and high cost. Utility Model Content
