As countries continue to implement LED lighting to replace traditional lighting development plans, a series of LED-related industries are rapidly expanding. Among them, the LED package in 2013 has a good industrial situation, and some manufacturers have expanded their production to prepare for the market competition in 2014.
The LED (Light Emitting Diode) package refers to the package of the light emitting chip, which is quite different from the integrated circuit package. LED packaging is not only required to protect the wick, but also to be able to transmit light. Therefore, LED packaging has special requirements for packaging materials. In fact, LED packaging is inseparable from the LED lighting industry. It has also played a very important role in the development of the entire LED industry chain, and its development prospects are extremely broad.
2013 LED packaging situation is good, companies have developed expansion plans In 2013, China's LED packaging output value growth rate is much higher than the global average, of which lighting is still the largest field of China's LED packaging market in 2013, accounting for 43. by Chinese LED commercial lighting The impact of rapid growth in market demand, the performance of China's lighting device packaging manufacturers represented by Mulinsen, Hongli Optoelectronics, and Changfang Lighting continued to flourish. The localization of high-quality chips has greatly improved the competitive position of China's LED lighting packaging industry. Domestic chips have already occupied more than 70 in the domestic chip market.
Looking at the major packaging companies, the capacity utilization rate in 2013 reached an average of 80 or more. There is a growth of 30 compared to last year. Many packaged listed companies have expansion plans: Hongli Optoelectronics has added 100 KK capacity in the first half of this year; Jufei Optoelectronics spent 100 million yuan on lighting LED device expansion project completed on September 30 this year; Ruifeng Optoelectronics 2013 In the first half of the year, the production equipment investment for the lighting LED product technology transformation project has been fully implemented, with an annual production capacity increase of 1,350 KK and an annual production capacity of lighting LED products of 2,470 KK.
How 14 years of Chinese enterprises grasp the LED packaging market After years of fierce competition, the domestic LED packaging market has matured. The competitiveness of a number of leading domestic packaging enterprises has been continuously enhanced and their scale has been continuously expanded. They have already started fierce competition with foreign-funded enterprises in domestic and foreign markets.
At the same time, however, there are still some shortcomings in technology and technology in China's packaging. Production costs continue to decline, and revolutionary technological breakthroughs are needed. Due to the small scale, insufficient funds and lack of upstream technical support, the domestic LED packaging enterprises are currently conservative in the research and development of new technologies, and are generally in a wait-and-see period. In the short term, the price of LED packaging products will decline, and companies with economies of scale and robust upstream chip supply chain will have certain comparative advantages in the competition.
Under this circumstance, China's LED packaging enterprises need to do a good job of technology integration and upgrading under the premise of a good industrial situation in 2013, so as to further expand the production scale while the product technology content has been fully improved, so that it can be reduced later. Production costs, providing some basic support.
Polyoxymethylene (POM), also known as acetal , polyacetal, and polyformaldehyde, is an engineering thermoplastic used in precision parts that require high stiffness, low friction and excellent dimensional stability.
2 Properties
♣POM is characterized by its high strength, hardness and rigidity to -40 °C. POM is intrinsically opaque white, due to its high crystalline composition, but it is available in all colors.
♣POM homopolymer is a semi-crystalline polymer (75-85% crystalline) with a melting point of 175° Celsius
♣POM copolymer has a slightly lower melting point of 162 – 173° Celsius.
3 POM advantages
♥High abrasion resistance
♥Low coefficient of friction
♥High heat resistance
♥Good electrical and dielectric properties
♥Low water absorption
