    Three Development Directions of Thick Film Chip Resistors

    Thick film chip resistors are relative to metal film resistors. The resistive film layer is relatively thick, and the thickness is generally 4 ??m. The manufacturing process adopts a new manufacturing process compared with the conventional columnar leaded resistors. The chip resistor is usually made of a ceramic substrate with 96% Al2O3 as a heat-dissipating substrate, Ag-Pd as a conductor material, oxides of ruthenium and osmium as a resistor material, a glass glaze as an encapsulating material, a terminal plating nickel tin, etc. . Through screen printing technology, sintering technology, laser trimming technology, slicing technology, end of silver coating technology, folding grain technology, electroplating technology, etc. more than 30 production and inspection processes carefully manufactured. The main development directions of thick film chip resistors are:

    Super miniaturization. At present, the 0402 and 0603 size chip resistors have become the mainstream in the market, but with the miniaturization and lightness of electronic products, especially digital products, the demand for 0201, 01005 products is increasing, especially 01005, the volume of the product Only 0.4 mm (length) ?— 0.2 mm (width) ?— 0.125 mm (height) and weighs only 0.04 g. At present, only a few Japanese enterprises and Taiwan enterprises in China can produce. In order to solve the production of small-sized products such as 01005, it must be In the traditional manufacturing process for upgrading, such as screen printing technology must use advanced CCD (electric coupling device) automatic alignment printing technology, the end coating must be used in recent years to develop sputter technology to solve the end surface problems, laser adjustment Resistance and electroplating must also use the latest special equipment to ensure the mass production of 0201, 01005 products.

    Environmental protection. The European Union's "Electrical and Electronic Equipment Waste Act" (WEEE) and the "Prohibition of Certain Hazardous Substances in Electrical and Electronic Equipment" (RoHs) have been in force in August 2005 and July 1, 2006, and their impact is global. Sexuality appears within range. Although the glass glaze film of the chip component is exempt from the scope, minimizing the use of glass glaze slurry can not only reduce the use of non-environmental materials, but also be a good way to save energy and reduce energy consumption. Metals and encapsulants, such as polymer resins, have also begun to be used gradually. According to statistics, end-face sputtering of base metals can reduce the cost of raw materials for product coating by more than 90%. The use of polymer resin not only reduces the cost of raw materials, but also significantly increases the product's resistance to pass.

    Ultra high resistance. Ultra-high resistance chip resistors, the main application products in high-performance electronic communication modules, high-precision precision electronic instruments | instrumentation and special military products. The maximum resistance requirement is up to 1T??, and the maximum working voltage requirement is up to 10kV. The main technical specifications of these products include resistance accuracy, working voltage, temperature coefficient, voltage coefficient, stability, etc. To ensure that these indicators meet the requirements of users, they must be There are technical breakthroughs, including the selection of slurry, the adjustment of the resistance, and the printing of encapsulants. Only after these technologies form a breakthrough can we ensure the mass production and supply of ultra-high-resistance chip resistors.

    Established in 1956, during the China first five-year-plan, Henan Xintaihang Power Source Co., Ltd. (Factory No.755) was the first R&D and manufacturing enterprise in China in the field of alkaline storage batteries and modular power system and it was also the military factory which owned the most varieties rechargeable batteries in domestic. Taihang was located in national Chemistry and Physicals Power Source Industrial Park, Xinxiang City, Henan, China.

    High Dishcharge Rate Nickel Cadmium Battery, KPH20~KPH500,  Max. discharge current ???5C

    The nickela€“cadmium battery (NiCd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. The abbreviation NiCd is derived from the chemical symbols of nickel (Ni) and cadmium (Cd).
