簡介 Brief Introduction MLCC簡介： 片式多層陶瓷電容器（MLCC）是適合于表面貼裝技術(shù)（SMT）的小尺寸、高比容、高精度陶瓷介質(zhì)電容器，可貼裝于印刷線路板（PCB）、混合集成電路（HIC）基片，有效地縮小電子信息終端產(chǎn)品（尤其是便攜式產(chǎn)品）的體積和重量，提高產(chǎn)品可靠性。順應(yīng)了IT產(chǎn)業(yè)小型化、輕量化、高性能、多功能的發(fā)展方向。 General Introduction Multi-layer ceramic chip capacitor is a kind of ceramic dielectric capacitor with small size, high capacitance per volume, high accuracy, suited surface mounted technology (SMT). It is widely used in electronic circuitry, mounted printed circuit board, and hybrid IC. These different functions require specific capacitor properties. MLCC的分類：根據(jù)所采用陶瓷介質(zhì)材料的類型，MLCC可劃分為兩大類：1類陶瓷介質(zhì)MLCC具有極高的穩(wěn)定性，其電容量幾乎不隨時(shí)間、交流信號、外加直流偏壓的變化而改變，同時(shí)具有極低介質(zhì)損耗，即高Q值。適用于對容量精度和應(yīng)用頻率要求較高的諧振電路。根據(jù)電容量的溫度系數(shù)又可分為溫度穩(wěn)定型與溫度補(bǔ)償型兩種。、2類陶瓷介質(zhì)MLCC具有很高的比體積電容量，適合用于旁路、耦合、濾波以及對容量穩(wěn)定性要求不高的鑒頻電路。在DC-DC(AC)變換器和開關(guān)電源濾波電路正逐步取代鉭電解電容器、鋁電解電容器。 MLCC can be divided into two classes:Class 1Dielectrics are used with very high Q and linear temperature coefficient in these capacitors. They can be distinguished into temperature compensating type and temperature stable type.They can be used in such applications as oscillators and filters where low losses, low capacitance drift or temperature compensation and high stability are required.Class 2These capacitors have a very high capacitance per volume and non-linear temperature characteristics. They are used for by-passing, coupling, filter and de-coupling. For instance, they can be substituted for the Ta, Al electrolytic capacitors in DC-DC(AC) converters and switching power suppliers. MLCC的制造工藝將化學(xué)組成和微觀晶相結(jié)構(gòu)符合設(shè)計(jì)要求的陶瓷原粉和有機(jī)粘合劑進(jìn)行充分混合成為陶瓷料漿，通過流延或噴涂等方式制得所需厚度的生坯膜片。在膜片上印刷內(nèi)電極后進(jìn)行疊壓、切割成為單個(gè)電容器生坯后于10001400之間進(jìn)行多層共燒，在所得瓷坯兩端進(jìn)行端電極金屬化處理后即制成MLCC成品。最后經(jīng)電性能測試和檢驗(yàn)合格，即可包裝入庫，并交付使用。Manufacture process of MLCC Ceramic powders, which formulation and crystal phase fitted the demand of designing, are carefully mixed with solvent and binder, and then finely milled as slurry. The very thin green sheets can be obtained by casting or spraying the slurry. After this, electrode is printed on the sheets which then be stacked, pressed and cut into chips. The green chip is co-fired at temperatures between 1000 and 1400 to become a monolithic block.The final product can be formed by metalizing the termination of the compact ceramic chip.
