Applicable industry explanation
Packaging is necessary for the manufacturing process of semiconductor electronic chips, and packaging technology is very critical for integrated circuits. Unless we have advanced production equipment and production lines, stable and safe gas supply equipment is also essential. The packaging equipment in the semiconductor industry will use the gas after matching, and only by ensuring the accuracy of the gas concentration and accuracy can the stability of the packaging quality be guaranteed, and continuous matching gas supply is also a necessary condition for packaging.
Unlike the special gas pipeline of laboratories and scientific research systems, the special gas system of the semiconductor industry represents the highest standards and requirements of the special gas industry. In addition to the safe and reasonable transportation of gas, it is a very high requirement to ensure the purity of gas and the production process requirements of semiconductors to the maximum extent. If the purity of a gas is not enough, a batch of products may be scrapped. If the flow and pressure are not enough, the equipment will not operate normally. The system solution is not perfect enough to meet the uninterrupted gas supply, which directly affects production.
