Reduce SMT Printing Defects: The Role of Full Auto Squeegee Blade Inspection Machine

Printing defects are one of the most common and costly problems in SMT production lines. Solder paste printing defects such as uneven thickness, missing printing, bridging, and insufficient solder not only lead to PCB scrapping and rework but also affect the reliability of terminal products. Many manufacturers do not realize that the root cause of these printing defects is often the abnormal state of the squeegee blade. The Full Auto Stencil Printing Squeegee Blade Inspection Machine effectively solves this problem by screening out defective squeegees in advance.
Abnormal squeegee blade states, such as uneven wear, burrs on the blade edge, and deformation, will directly affect the uniformity of solder paste printing. When the squeegee blade is worn unevenly, the solder paste cannot be evenly applied to the PCB, resulting in uneven printing thickness; burrs on the blade edge will cause missing printing or bridging; and deformation will lead to insufficient solder. These defects will be transmitted to subsequent processes such as placement and reflow soldering, triggering batch quality accidents and increasing production costs.
The Full Auto Stencil Printing Squeegee Blade Inspection Machine can quickly and accurately detect all types of abnormal states of squeegee blades before they enter the printing process. By automatically inspecting key indicators such as blade edge flatness and wear level, the machine ensures that only qualified squeegee blades are used for printing, thereby stabilizing the printing process and greatly reducing the rate of PCB printing defects. In practical applications, manufacturers who use this machine have seen a significant reduction in printing defects, with some achieving a defect reduction rate of more than 60%.
In addition to reducing printing defects, the Full Auto Stencil Printing Squeegee Blade Inspection Machine also helps improve the reliability of terminal products. By ensuring the quality of solder paste printing, the machine reduces the failure rate of terminal products, enhances customer satisfaction, and helps manufacturers build a good brand reputation.
