Mold testing, mechanical testing, Motorcycle detect sophisticated detection, regular contact detection applications, some detection application, but we rarely come into contact with, however, only in the application of professional products, we can see. For precision measuring instruments in these areas, we know knowledge is little lithium batteries chip detection is one of them. Lithium batteries chip detection applications for the sophisticated detection equipment, a lot of people do not know, even the the battery supplier persoel do not know, only the most professional fishes lithium batteries chip detection understand about the lithium battery knowledge of chip detection. ...

This article will focus on the patte of Fujian, Jiangxi and other southe regions of the chip industry to do depth profiling. Number of enterprises accounted for 24% Fujian has been put into production LED epitaxial silicon vendors a total of three, Xiamen Sanan dry according to Xiamen and Xiamen Jingyu, in the construction of the project 5. Xiamen Sanan Optoelectronics already have three production base in Xiamen, Tianjin and Wuhu, become the delay chip leading enterprises at home and abroad; Xiamen dry according to the main red, yellow, light LED chip suppliers, currently has two production bases in Xiamen and Yangzhou ; Xiamen Jingyu Taiwan Epistar chip processing base in the ...

Similar the ordinary infrared LED shape and visible LED, but it emits infrared light. Its pipe pressure generally drop to about 1.4v, generally less than 20mA operating current. In order to adapt to different operating voltages, the circuit often string current limiting resistor.   Emitting infrared rays to control the corresponding controlled apparatus, which controls the distance and transmission power proportional. In order to increase the operating distance of the infrared, the infrared light-emitting diode in the pulse state, because the effective transmission distance of the pulsating light (modulated light) with the pulse of the wind is proportional to the call flo...

To benefit from the demand for large-size TV and direct type LED-backlit LCD TV Product warming, LED chip price decline this year less than in previous years, the reduction from 20%, Epistar, Formosa Epitaxy LED chip plant operating pressure slightly slowed. Epistar general manager Zhou Ming Jun, backlight chip products offer fall further limited space, although the first quarter is traditionally the low season, entering the season with the second quarter in succession, however, demand is expected to rebound, prices should also have some supporting role. Zhou Ming Chun pointed out that South Korean companies Attacking LED lighting action is positive, and the South Korean compani...
