Sputtering target process flow:
Raw powder → powder smelting → powder mixing → press molding → atmosphere sintering → plastic processing → heat treatment → ultrasonic flaw detection → water cutting → mechanical processing → metallization → binding → ultrasonic testing → ultrasonic cleaning → final inspection → packaging and delivery.
Component quality control
Composition analysis of raw materials:
Through the detection and analysis of ICP, GDMS and other equipment, the content of metal impurities is ensured to meet the standard of purity;
The content of nonmetallic impurities is detected by carbon-sulfur analyzer, nitrogen-oxygen analyzer and other equipment.
Metallographic inspection analysis:
The target material is detected by flaw detection equipment to ensure that there are no defects and shrinkage cavities in the product;
Through metallographic test, the degree of grain inside the target is detected to ensure that the grain is fine.
Appearance size detection:
Measure the product size by micrometer and precision caliper to ensure that it meets the requirements of customer drawings;
The surface smoothness and cleanliness of products are measured by surface cleanliness measuring instrument.
Packaging and storage instructions
Out-of-warehouse packaging: internal vacuum bag vacuum packaging, external labeling (packaging according to demand), carton foam pad express transportation.
Storage method: store in a dry environment, avoid moisture, seal and package, handle with care, and prevent pressure and collision.
Caution: Please wear dust-proof gloves to operate before use, and observe whether the target surface is clean, so as to avoid direct hand contact operation and other foreign objects polluting the target.
