In the CMP process, products with large particle size range should be filtered, effective particles should be retained for grinding, and large-size particles that may scratch the surface should be removed. In view of the strict particle interception performance of the filter core, as many effective particles should be released as possible to efficiently intercept large-size particles.
With the refinement requirement of the processing line width, the clean control of the product becomes more and more stringent. The precipitation requirement of various pollutants and metal ions puts forward higher requirements for the production of the filter element. Da-li filtration combines with practice to provide high purity products for process upgrading and ensure product quality.
The plant system needs to provide a stable supply of clean chemicals, ultrapure water, and clean process gases throughout the FAB. This puts forward high requirements for the stability and consistency of the filter element used in each section. Hangzhou Dali's large flow filter element, security filter element, high-precision folding filter element and perfluorinated filter element series provide stable filtration service for factory management system.
During the manufacturing process of flat panel display, the performance of filter products directly affects the quality and yield of finished products. Especially in the high generation line, the problem of filter products will cause large quantities of scrap and loss. Dali filter provides customers with stable and reliable products according to the requirements of each process, analyzes and solves the problems in each process, optimizes the products and reduces the cost.
The power system needs to work continuously for a long time to provide clean chemicals, ultrapure water, and clean process gases for high-generation plate display manufacturing, which requires high stability of filtration. The filter products of Hangzhou Dali provide reliable guarantee for the smooth operation of the manufacturing power system of flat panel display.
As a key material in semiconductor manufacturing, clean electronic chemicals play a key role in the semiconductor manufacturing process. Various electronic chemicals with different characteristics have different requirements on filtration products, and have strict requirements on the cleanliness and low precipitation of filtration products. Dali company USES advanced equipment and technology, strict control of filtration products cleanliness, production of low precipitation, low metal ion produc
In the digital information age, storage media has developed from paper carrier to hard disk, flash memory, U disk, SD card and other new storage media. In order to manufacture portable and large-capacity data storage products, the equipment and process depend on the pollution control and filtration purification technology of each process. Hangzhou Dali develops and produces various advanced filtration products and related technologies to meet customers' personalized process and requirements.
