2D Solder Paste Thickness Inspection Machine
Brief Introduction (Optimized for Buyers)
As Surface Mount Technology (SMT) advances, electronic components become increasingly smaller, packaging density becomes denser, and solder joints shrink correspondingly. Nearly 70% of PCB assembly defects are caused by improper solder paste printing.
The SH-110-2D Solder Paste Thickness Inspection Machine is designed to solve this problem. It effectively identifies potential defective solder deposits before component placement, provides accurate SPC control data (CPK, Cp), and significantly reduces defect rates.
In today's competitive electronic manufacturing environment, lower defect rates translate directly into higher profits. Strict process control requires factories to demonstrate their capability in managing solder paste printing during production. This machine provides that proof.
Beyond Solder Paste: The SH-110-2D can also be used in other production fields. Any geometric information of objects and components within 10 mm height can be precisely and non-contact measured.

Operating Principle (Technical Explanation for Engineers)
The non-contact thickness gauge emits a very fine laser beam at a fixed incident angle onto the measurement target. Because the target (solder paste) and its surrounding substrate (PCB surface) differ in height, the reflected sensor receives multiple laser differences.
Based on the observed data, the analysis program—using trigonometric functions—rapidly calculates and outputs precise information about the measurement target, including height, width, area, and derived volume.
