A few days ago, the company's wholly-owned subsidiary, Shenzhen Jiejia Xinchuang Technology Co., Ltd. (hereinafter referred to as "Jiejia Xinchuang") came to the good news, the first new film capacitor winding coating equipment has been successfully shipped. The coating width of the coating equipment is 620mm, and the line speed is adjustable 600~1200m/min. The successful delivery of the equipment marks that Jiejia Xinchuang has entered the film capacitor equipment industry, and has fully won the trust of customers, and has built a vacuum winding technology platform in an all-round and steady manner.
Ultra-thin capacitors are on the rise
With the continuous improvement of the country's support for electronic components, the scale of China's film capacitor market is increasing day by day, and its performance in the new energy track is particularly prominent. The production of capacitor film requires ultra-thinning and temperature resistance, and the core problem is how to control the thickness and crystallinity of the capacitor film in the evaporation process of metal film, so as to improve the performance of the capacitor. Due to the ultra-high requirements for product quality and production stability, the global equipment supply is insufficient, and Chinese manufacturers are facing challenges, and there is a supply gap in the domestic market.
Innovate and optimize to improve product performance
According to the customer's product technical needs and cutting-edge process routes, Jiejia Xinchuang has tailored a complete solution for it:
Deeply cultivate high-efficiency deposition evaporation sources and supporting cooling systems, develop low-temperature cooling deposition methods with independent intellectual property rights, and the cooling temperature control range ± 1°C.
According to customer requirements, the equipment is matched with high, medium and low multi-line speeds, especially the stability of high line speeds of 600~1200m/min has been verified, the production efficiency is improved, and it is more suitable for the production needs of mass production.
In order to improve the product yield, the R&D team has continuously improved the online monitoring and adjustment function. At the same time, the square resistance of the metallized film is reduced, thereby improving the withstand voltage capacity.
The original design of the safety film printing module has higher withstand voltage performance, and at the same time greatly improves the safety and reliability of the capacitor film. When the capacitor suffers from an internal short or open circuit, the safety film function is activated, allowing the capacitor to automatically disconnect the circuit in the event of a fault. This mechanism prevents arcing and heat dissipation, significantly reducing potential safety hazards.
The product has been verified by a number of tests and shows excellent performance. The uniformity of the square resistance test can reach up to ±5%, and the OD value ranges from 0-3. In the peeling experiment, there was basically no detachment or film loss of zinc-aluminum film on site. The zinc layer is not easy to corrode, and when the safety film is not coated, the copper corrosion time is up to 10min, which is higher than the industry standard. After strict process verification, coating quality, consistency, safety and other dimensions can meet customer needs.
Relying on years of accumulation in the field of vacuum coating equipment, Jiejia Xinchuang has independently developed vacuum winding platform, vacuum evaporation coating equipment and other products, mastered a variety of evaporation coating technologies, and has been widely deployed in the photovoltaic perovskite battery, lithium battery composite current collector and consumer electronics market. Since its inception, the company has been adhering to the development route with independent innovation as the core and overcoming difficulties. In the equipment market, the company is based on the advantages of high reliability and high stability of products to meet the needs of customers in different application scenarios, and continue to output to promote the pace of industrial development.
