Precision thin-walled Teflon corrugated pipe mass production, helping the miniaturization development of the microelectronics industry
With the development of the microelectronics industry towards "smaller and more refined" direction, the requirements for the dimensional accuracy and surface quality of precision pipes are becoming increasingly stringent. Recently, a precision manufacturing company launched a precision thin-walled Teflon corrugated pipe product, which has a dimensional tolerance controlled within ± 0.01mm and a wall thickness of up to 0.1mm. It has successfully adapted to scenarios such as chip cooling and precision fluid transport in the microelectronics industry, providing key component support for the miniaturization development of the industry.
The chip cooling pipeline and photoresist transport pipeline in the microelectronics industry require efficient fluid transmission in a very small space. Traditional ultra soft Teflon bellows are prone to problems such as high fluid resistance and low heat dissipation efficiency due to low dimensional accuracy and uneven wall thickness, which affect equipment performance. A precision manufacturing company has introduced micro extrusion molding equipment imported from Germany, combined with self-developed "constant temperature control+precision mold" technology, to achieve precise extrusion of PTFE raw materials: by monitoring the extrusion temperature and pressure in real time, the deviation of the outer diameter of the pipe does not exceed 0.01mm; adopting a special mold polishing process to make the roughness Ra of the inner wall of the pipeline ≤ 0.01 μ m, reducing fluid transport resistance. At the same time, the product uses food grade pure iron fluorine dragon raw materials without any additives, meeting the strict cleanliness requirements of the microelectronics industry.
In the chip cooling system of a semiconductor enterprise, the use of precision thin-walled Teflon tube improved the temperature control accuracy of the chip to ± 0.5 ℃, reducing fluid energy consumption by 30% compared to traditional pipelines, while reducing pipeline space occupation, creating conditions for miniaturization of chip packaging. ”The technical director of a precision manufacturing company stated that the product has passed ISO 9001 quality management system certification and SGS cleanliness testing, and is currently being supplied in bulk to companies such as SMIC and Huahong Semiconductor. In the future, the company will also develop ultra micro PTFE Corrugated Hoses with diameters less than 1mm to further meet the cutting-edge needs of the microelectronics industry.
