Whether to master the core technology of copper foil additives is an important indicator to measure the market position of an electronic copper foil company. A few days ago, Anhui Tongguan Copper Foil Co., Ltd.'s fifth and sixth workshops realized the localization of additives, marking the company's five or six workshops to complete the localization of additives.
Lu Binghu, Secretary of the Party Committee of Tongguan Copper Foil Company, said: "Additives are the core skills that copper foil companies must master. It directly determines the main performance of copper foil products. Only by controlling the core technology of additives in their own hands can the company ensure its market leadership. status."
The complete set of R line production equipment and processes were imported from South Korea. Since the production started in January 2017, imported additives have been used. The core additives are completely dependent on imports. Not only the procurement cycle is long and they are greatly affected by the external environment, but with the continuous improvement of customer demand, the tensile strength of the copper foil produced by the original additives cannot meet the needs of high-end customers, which seriously affects The company's high-end customer rate. Therefore, the company is committed to the localization of additives.
In November 2018, the Fifth and Sixth Factory established a research team on domestic additive party members. "It didn't go well at the beginning. At that time, it was the first time that domestic additives were used on Korean equipment. The choice of additive ratio was to cross the river by touching stones." Wang Junyi, the factory director, told the author. At the beginning of switching domestic additives, the production efficiency of the system is low. Compared with the use of imported additives, the production output is reduced by 40%, and the color difference of the produced copper foil is serious.
"If it doesn't work 10 times, we will try it 100 times and 1000 times. If someone else can do it, why can't we do it?" Wang Junyi said. In order to be successful in the test, the two section lengths are often 24-hour alternate tests. After nearly half a year of groping, they finally mastered the best additive ratio and production parameters.
"The tensile strength of the copper foil we produce now is 10% higher than that of imported additives. The production efficiency and production capacity are consistent with imported additives. Domestic additives have completely replaced imported ones." Wang Junyi said proudly.
