In the field of high-end manufacturing, cleanliness control has become one of the core metrics for assessing product quality. As industrialization deepens, industries such as semiconductors, pharmaceuticals, aerospace, and automotive manufacturing are imposing increasingly stringent requirements on the surface cleanliness of components; the presence of even minute particles can not only compromise product performance but also pose significant safety risks. As a domestic high-tech enterprise dedicated to the R&D of cleanliness-testing technologies, Chongqing Hake Technology Co., Ltd. (Official website: www.qjdyq.com ) Our in-house developed automatic cleanliness analysis system leverages cutting-edge technology to overcome the limitations of conventional inspection methods, delivering high-precision, intelligent solutions for industrial cleanliness control.

I. Core Principles of the Automated Cleanliness Analysis System

Chongqing Hake Technology Co., Ltd. With more than a decade of deep expertise in the field of cleanliness inspection, leveraging our proprietary technologies and the strategic integration of industry resources, we have developed an automated cleanliness analysis system whose core lies in... High-Resolution Optical Imaging and High-Precision Scanning Technology It performs full-field, high-precision scanning of the surfaces of manufactured or cleaned workpieces. Equipped with imported optical components and advanced image-processing algorithms, the system can rapidly detect surface particulates, dust, and residual contaminants, automatically quantifying particle count, particle size, two-dimensional morphology, and spatial distribution density. It then generates inspection reports that comply with international standards such as ISO 16232 and VDA 19, providing objective and precise data to support cleanliness assessments.

As a national-level high-tech enterprise and a provincial-level specialized, refined, distinctive, and innovative SME, Hako Technology With technological innovation at its core, the company’s independently developed automated cleanliness analysis system has obtained ISO 9001 quality management certification and is widely deployed in industries such as automotive components, precision electronics, and aerospace, helping enterprises achieve standardized, automated, and intelligent cleanliness testing.

II. Two- and Three-Dimensional Analysis Techniques: Breaking Through the Bottleneck of Traditional Two-Dimensional Inspection

Traditional cleanliness inspections largely rely on two-dimensional analysis, which can only provide basic information such as the planar dimensions and area of particles. Unable to reveal the three-dimensional morphology, spatial distribution, and depth characteristics of the particles. In high-precision manufacturing environments, the three-dimensional parameters of particles—such as volume, height, morphological profile, and spatial orientation—directly determine their hazard level. For instance, stacked particles on semiconductor chip surfaces or sharp, hard particles in automotive hydraulic systems are极易 misclassified using two-dimensional inspection alone, thereby creating hidden quality risks.

To address this industry pain point, Chongqing Hake Technology Co., Ltd. In the automatic cleanliness analysis system Integrated high-end 3D analysis module (High-end / Optional), breaking the limitations of two-dimensional inspection. System integration Multi-focus stacking (EFI), laser confocal scanning Advanced cutting-edge technologies, employing high-precision Z-axis layer-by-layer focusing scanning, reconstruct a three-dimensional particle model and accurately acquire particle characteristics. Length, width, height (Z-axis), volume, surface area, morphological roughness By leveraging key core parameters, we have achieved an upgrade from “planar detection” to “three-dimensional analysis.”

Core Particle Parameters Provided by 3D Analysis

• Three-dimensional dimensions : Precise measurement of particle length, width, height (Z-axis), equivalent volume, and surface area;
• Morphological characteristics : Generate high-resolution chromatograms and three-dimensional contour models to analyze particle surface roughness, peak-to-valley differences, and edge characteristics;
• Spatial distribution : Reconstruct the stacking configuration, contact angles, and spatial orientation of particles on the workpiece surface, and identify complex operating conditions such as particle aggregation and overlap.

III. Industry Application Value of 3D Analysis Technology

In high-end manufacturing scenarios, Hako Technology The 3D particle analysis capability of the automated cleanliness analysis system has become a critical technological enabler for addressing key industry pain points:

• Semiconductor industry : Precisely measures the stacking height and morphology of minute particles on the chip surface, provides early warnings of risks such as circuit shorting and performance anomalies caused by these particles, and thereby ensures high chip yield.
• Automotive manufacturing industry : For core components such as engines and transmissions, the three-dimensional dimensions of hard, sharp particles are identified to assess their wear risk to hydraulic systems and transmission components, thereby meeting the VDA 19 standard’s requirements for detecting “killer particles.”
• Pharmaceutical industry : Analyze the volume and morphology of particles on pharmaceutical raw materials and packaging surfaces to prevent particle contamination from compromising drug purity and medication safety, thereby meeting GMP requirements in the pharmaceutical industry;
• Aerospace industry : Detecting minute particulates on the surfaces of aircraft structural components and precision instruments, assessing their impact on structural integrity and instrument accuracy, and ensuring flight safety.
