There are not many manufacturers who have mastered and produce UVLEDs in China, but not as many as other industries. However, how should UVLED choose manufacturers in these suppliers?. So how can we produce high -quality UVLEDs? The following is a list of you: 1. Fundamental factors Actually, choosing a high -quality UVLED can start from the chip to the assembly. During this period, there are many factors that need to be considered. In the conditions that determine all performance indicators of UVLED, the light and chemical materials used in the production process of the wafers are very important factor. A 2 -inch wafer can cut more than 6,000 UVLED chips, which only has the performance indicators of individual chips different from the overall. And the difference in color, brightness, and voltage drop by chip manufactured by an excellent chip producer is very small. In addition, the impact of packaging materials is quite large. Second, UVLED manufacturers with excellent classification capabilities can not only create high -quality chips, but also have the ability to classify packaging according to the color, brightness, voltage drop and perspective of UVLED. High -quality UVLED supplier will provide customers with the same work characteristics of products. Third, the product supporting ability, in addition to the separation of UVLED, the assembly and power supply of UVLED, have a very important impact on its performance, brightness and color indicators. Because environmental temperature, working current, circuit structure, peak and environmental factors can affect the performance indicators of UVLED. Proper circuit design and assembly are the key to protecting UVLED and ensuring performance. With the rapid growth of UVLED demand, manufacturers and assembly factories that serve the global market have also increased rapidly. Therefore, in addition to accurately screening UVLED suppliers through existing experience, OEM manufacturers must also examine their circuit design and assembly techniques to ensure the design specifications and whether the design provides sufficient heat dissipation capabilities, because the UVLED failure and performance will be faulty and performance The main factor of inconsistency is overheating. Fourth, third -party testing In order to eliminate the unfairness in the test, many companies entrust third -party to test the assembly and circuit structure of UVLED. During the test process, tests such as pressure, temperature circulation, voltage fixation/change, current fixation/change, etc. test, other tests under other harsh environmental conditions determine whether UVLED meets the requirements of the application requirements. A large number of parameter changes that occur before and after the test must be recorded, and at the same time, the changes in the test of LED brightness, color and voltage decrease must be monitored. In fact, if a low -quality LED has a higher driving current, it will brighter than high -quality LEDs in the early stages of work. If the application requires a high -end solution, the selection, design experience, and testing of chip suppliers are all factors that should be considered.
