A soldering method for blind slot PCBs includes the following steps: S1: Pre-soldering preparation: Inspect, clean, and bake the blind slot PCB; S2: Determine the solder paste printing method: For non-blind slot pads, use traditional stencil printing of solder paste; for blind slot pads, use a spray gun to spray solder paste; S3: Component mounting: Use a pick-and-place machine to mount components; S4: Assembly fixture: Assemble a detachable soldering fixture according to the component distribution on the PCB; S5: Soldering the PCB: Set the reflow oven temperature profile and perform soldering; S6: Component removal: After soldering, remove the workpiece, rinse with water, and inspect. The advantages of this invention are: Combining stencil printing and spray gun printing to apply solder paste improves production efficiency and saves production costs; modular soldering fixtures reduce soldering deformation caused by inconsistent thickness of the blind slot PCB, reducing the soldering defect rate; and reducing the reflow oven heating rate reduces PCB deformation.

This invention discloses a 3D printing platform leveling and printing quality monitoring system and method based on vision and laser fusion detection. The system includes a vision detection module, a laser ranging module, a fusion calculation module, an AI recognition and decision-making module, and a control feedback module. Both the vision detection module and the laser ranging module establish bidirectional communication connections with the fusion calculation module to match the timing of image and distance information acquisition. This application effectively solves the problems of insufficient accuracy and instability in traditional technologies. By constructing a collaborative detection structure through the vision detection module and the laser ranging module, a triangulation subsystem of laser and vision detection modules is formed, completely overcoming the inaccuracy problem of traditional probes on highly reflective surfaces or magnetic plates. Simultaneously, it avoids the interference of environmental temperature, humidity, and material properties on measurement accuracy, significantly improving the stability and accuracy of the detection.
