Medallions manufacturer, Jiangsu Medallions, Medallions Sidon lighting

 Huizhou City Industrial Development Co., Ltd. Sidon describes the application of LED related products 2, soldering temperature of 260 ℃, 3 seconds. Temperature is too high for too long will burn the chip. In order to better protect the LED, LED Colloid and PC board should be kept more than 2mm pitch Medallions, so that the soldering pins dissipate heat. 3, LED's normal operating current of 20mA, small fluctuations in voltage (eg 0.1V) will cause large fluctuations in current (10% -15%). So Medallions brand manufacturers, circuit design should be paired according to different LED current limiting resistor voltage drop, in order to ensure LED in top working condition. Current is too large, LED will shorten the life of the current is too small, can not reach the desired intensity. Usually in the quantities will be LED spectral separation, that same package the product in the LED light intensity, voltage, light color is, and to indicate on the spectral color table. Huizhou City Industrial Development Co., Ltd. Sidon describes Note the use of SMD LED package LED industry chain can be divided into five parts. First, the raw materials. Second, LED upstream industry, including epitaxial materials and chip manufacturing. Three, LED midstream industry, including various LED devices and packaging. Four, LED downstream industries, including various LED application products industry. Fifth, testing equipment and production equipment. About LED upstream, midstream and downstream industries, there will be described in detail here below focuses on industrial raw materials and production equipment and testing instruments industry. LED light-emitting device material includes a substrate material and a GaAs single crystal, an aluminum nitride single crystal and the like. Most of them are group III-V compound semiconductor crystal Medallions wholesale, production technology is relatively mature, has opened polishing levy supplier that is used. Other materials as well as metallic gallium of high purity, high purity metal organic sources, such as trimethyl gallium, triethyl gallium, trimethyl indium, trimethyl aluminum and the like, high-purity ammonia gas, nitrogen, hydrogen and the like. Purity of the raw materials are generally required in 6N or more. Packaging materials epoxy, ABS, PC, PPD and the like.
