6-inch LED epitaxial emission measurement speed is tested In addition, Huang Qinming also observed changes in the LED market in 2011, in which the demand for 6-inch LED epitaxial wafers, LED rapid measurement and lighting applications is gradually increasing. As the area of ​​LED epitaxy increases, the measurement efficiency is bound to decline, in order to maintain the measurement level. To improve the measurement speed, Zhimao Electronics has laid out the LED dual-chip test patent technology and 6-inch LED epitaxial wafer measurement technology in advance, and calculates LED lumens through solar chips, which is expected to maintain the advantage of leading the opponent for two years. In fact, in addition to increasing the size of LED epitaxial wafers, manufacturers have gradually increased their production capacity, including Epistar, AUO, and Ronda, all of which announced that they will expand their 4-inch epitaxial wafer capacity in 2011. As for foreign manufacturers, South Korea's Samsung (Samsung) used a 4-inch machine to mass produce LED epitaxial in 2010, and Philips Lumileds mass-produced a 6-inch LED epitaxial at the end of 2010. The global LED supply is greatly increased. LED lighting applications will drive the 2011 LED market Huang Qinming said that the LED epitaxial wafer will be upgraded from the original 2 inch to 6 inch, so the demand for the test machine of the new LED epitaxial wafer is expected to emerge in 2011. As AUO's LED manufacturer Longda Electronics announced the production of the first 6-inch LED epitaxial wafer at the end of 2010, it still takes about 6 months for LED epitaxial from the laboratory development stage to the actual production schedule. Therefore, the market estimates that the Ronda 6-inch LED epitaxial wafer is expected to enter mass production in the second half of 2011. At that time, it will set off a large-scale, high-capacity LED epitaxial war.

The LED test process is divided into three stages. The first stage is LED wafer and wafer test, including LED overall power test system, LED epitaxial detection system, locking such as Canyuan, Jingyuan Optoelectronics, etc. The second phase is the LED package test, which is based on the chip-type AC light-emitting diode lighting test system, which can meet the LED packaging factory like Yiguang Electronics; the third stage is the LED module test, which can be divided into LED light. Testing, LED power driver testing, etc. In fact, Zhimao Electronics has a complete layout in the LED test market, covering the LED test requirements from upstream to downstream (Table 1). As the future demand for LED lighting applications emerges, it is bound to face high power and heat dissipation issues. Huang Qinming revealed that Zhimao There is a corresponding measurement scheme for electronics.
