Mainly look at the strength! Analyze why China can achieve the dominance of LED packaging

OFweek Semiconductor Lighting Network China is a large LED packaging country. It is estimated that 80% of the world's LED device packaging is concentrated in China, and it is distributed in various US, Taiwanese, Hong Kong and domestic packaging companies. China's LED packaging companies have a high market share. In the field of high-end LED device packaging, some Chinese companies have made major breakthroughs. With the continuous maturity of process technology and the accumulation of brand reputation, China's LED packaging companies will play an important and leading role in China's LED application country.

The following small housekeepers elaborate on these differences from all aspects of the LED packaging industry chain.

1, LED chip difference

At present, there are about 10 LED chip companies in mainland China, which started late and are not large enough. The largest LED chip companies have an annual output value of about 300 million yuan, and the average annual output value of each is between 1 and 200 million.

The performance of LED packaged devices depends on the LED chip by 50. The core indicators of the LED chip include brightness, wavelength, failure rate, antistatic ability, attenuation and so on.

At present, most of the small and medium-sized chips of domestic LED packaging enterprises use domestic brands. The chip performance of these domestic brands is small compared with foreign brands, and it has good cost performance and can meet the needs of most LED application companies. In particular, the performance of some chip brands has been comparable to that of foreign brands. Through the cooperation of packaging technology, it has been able to meet the needs of many high-end applications.

2, package production and test equipment differences

LED main packaging production equipment includes solid crystal machine, wire bonding machine, sealing machine, spectrophotometer, dispensing machine, smart oven and so on. Five years ago, LED automatic packaging equipment was basically the world of foreign brands, mainly from Europe and Taiwan. China only has a small supply of semi-automatic solid crystal and wire bonding equipment. In the past five years, China's LED production equipment manufacturing industry has made great progress. Nowadays, automatic die bonding machines, automatic sealing machines, spectroscopic color separation machines, automatic dispensing machines, smart ovens, etc. are available from manufacturers. Good value for money.

At present, among the LED packaging companies in China, LED packaging companies in the forefront have the world's most advanced packaging equipment, which is determined by the advantages of latecomers. In terms of hardware level, China's above-scale LED packaging companies are the most advanced in the world. Of course, some of the higher level test and analysis equipment has yet to be further equipped.
