Second, core technology and product development

Yuyang Technology uphold the spirit of craftsmanship, deep cultivationMLCC行业20Surplus load, invest heavily in science and technology research and development, focus on miniaturization/Ultra-miniaturization, ultra-high volumeMLCCProduct development, up to now,ISimilar porcelain technology to basically achieve a comprehensive replacement of Japan and South Korea,IIIn terms of porcelain technology, it partially replaces Japan and South Korea, and the products are iterated from the mass production of ultra-micro-1gen 0201, ultra-micro-2gen 01005 to ultra-micro-3gen 008004, reaching the advanced technical level of the industry。Recently, Yuyang successfully developed and produced 008004 specification products MLCC products as the first domestic authority through the China Saibao Laboratory industry and information Technology Ministry Electronics fifth Institute testing and identification。superminiatureMLCCThe anatomy of appearance size is shown in figure2-1

1Core process research and development technology

Yuyang technology in the early stage01005MLCCBased on the research, development and trial production of the product, the number of layers is further increased, the thickness of the medium is reduced and the capacity is increased01005The capacity coverage of the size product has been successfully developed through the improvement of ultra-miniature screen printing technology, precision cutting process, and precision end sealing process008004Size specificationMLCC

The core technologies of the products include: submicron/Design technology of nano-resistant ceramic and base metal electrode material system;Ultra-micro radio frequency microwaveMLCCBase metal material system design technology;superminiatureMLCCStructure design and precision positioning processing technology;superminiatureMLCCReductive atmosphere stripping sintering technology;Micro chip element end electrode processing technology;The core research and development technology of micro-chip component braid technology。

2Core material process research and development

Yuyang Technology with anti-reduction ceramic mediaNiCuElectrodes composed of base metal electrodes (BMEMaterial system as the core material process, instead of conventionalMLCCA complete monolithic structure is obtained by co-firing several overlapping internal electrodes and thin ceramic medium at high temperature。Improved the oxidation resistance of high temperature co-firing for a long time PtPd Other noble metal inner electrode materials (NME) a large amount of consumption, resulting in MLCC The problem of excessive costs。

3Core production process research and development

Yuyang Technology based on existing micro MLCC The technical basis, combined with ultra-microMLCC Based on the high precision requirements of the products, combined with its own design and development capabilities and international first-class R & D and process technical support level, the process route of the project is determined as follows: the use of international advanced automation, high-precision key production equipment and independent development of key equipment, the selection of sub-micron ultra-fine anti-reducing ceramic thin layer dielectric materials NiCu Multiple layers of electrodes in equal base metal are overlapped in neutral (N2) or reducibility (N2+H2Sintering in the atmosphere ensures that the electrode is not oxidized and maintains excellent dielectric properties。Build on BME Technology based ultra micro MLCCPlatform for R&D and pilot production。Relative to the present PdAg Such as precious metal electrode material system, the cost of high capacity specifications has been greatly reduced, so as to achieve high performance and low cost by improving technical content, and enhance the international competitiveness of products。

Yuyang Technology has introduced the most advanced technology in the world today SLOT-DIE Ultra-thin casting equipment, high precision optical positioning printing, lamination, cutting equipment, atmosphere sintering kiln, end electrode preparation and automatic test equipment。The specific process flow is shown in the figure 2-2所示。

Iii. Product introduction and application scope

Multilayer ceramic capacitorMultilayer Ceramic CapacitorMLCC(also known as monolithic capacitor, it is composed of a ceramic dielectric diaphragm with a printed electrode (inner electrode) that is superimposed in a misplaced manner, and a ceramic chip is formed by one-time high-temperature sintering, and then a metal layer (outer electrode) is sealed at both ends of the chip to achieve the required capacitance value and other parameter characteristics。MLCCIt has the characteristics of small size, wide frequency range, long life and low cost, mainly used in mobile terminals, digital home appliances, communication equipment, computers, automotive electronics, industrial control equipment and other electronic machines Oscillation, coupling, filter, bypass circuit, is the world's largest electronic components。

Yuyang Technology products cover vehicle gauge level, industrial level, ultra-high temperature and other related levels, product features include low loss, high capacity, low loss and highQ, low loss RF high power and other industry advanced product features, to reach the industry leading level。
