EMC packaging will "break the butterfly"
[Source: LED Engineering's "good LED products," May issue of the magazine reporter / Zhu Chunwei] EMC (Epoxy Molding Compound) is the introduction of new Epoxy materials and etching technique in the package Molding device highly integrated framework form. Due to changes in materials and structures, it is characterized by high heat resistance, UV resistance, high integration, high current, and small volume. Under the premise that LEDs require high integration, reduced light cost, and high reliability, they have been developed with the characteristics of the IC industry. EMC has advantages that ceramics and PPA can't match in certain specific fields.
EMC bracket molding material is epoxy resin. This material has the advantages of high stability against UV, high temperature and low expansion coefficient. Therefore, the bracket factory also said that the backlight market at home and abroad will gradually switch to EMC bracket, including the lighting market. If so.
EMC is optimistic about the performance of many packaging companies due to good performance, have announced that they will increase investment. However, due to the comprehensive consideration of technology, market and cost, but currently only in the field of LED lighting packaging, Tiandian has achieved mass production. Other large manufacturers are still in the evaluation stage and have not achieved mass production.
High-profile EMC
Due to the excellent mechanics, adhesion and corrosion resistance of epoxy film plastic (EMC) materials, the curing shrinkage rate and thermal expansion coefficient are small and the dimensional stability is good. Its good processability and comprehensive performance make it widely used in the electronics field. In view of the good characteristics of EMC, the field of packaging has begun to be introduced and has been well applied in backlighting.
Lin Guangmin, director of Everlight Electronics, said that in addition to actively improving the luminous efficiency and thinning of the next-generation 7020 solution, the LED packaging factory is also reducing the cost of LED package components by cost-competitive EMC. .
According to the cost structure analysis of LED components, the wire bracket accounts for about 15% of the BOM component of the LED component. In other words, the new generation 7020 will be reduced by 15% compared with the traditional 7020 and 7030 developed by PCT and PA9T plastics.
In terms of cost reduction, the EMC bracket also exhibits excellent performance in LED high-power packages, providing support for the popularization of LED indoor lighting.
“Compared to PPA and ceramic substrates, EMC packaging with epoxy resin can realize large-scale production, reduce production cost, design flexibility, size design, smaller and easy to cut.†Gong Weibin, chairman of Ruifeng Optoelectronics, said, “Can Driving a very high wattage in a small volume, more than double the performance of the original product, thereby reducing the cost, and at the 0.5-2W stage, both ceramic and PPA are not competitive with EMC and replaced by it. â€
Taiwan’s Changhua Electric Materials announced that it will continue to invest NT$1 billion to expand its production capacity for LED EMC leadframes. After the expansion is completed, shipments of L ED leadframes will grow from the current 70 KK (70 million) / month to 2000 KK (equivalent to 2 billion) / month.
Huang Jianeng, chairman of Taiwan's IC packaging materials channel, said that the current LED lighting products are becoming lighter and shorter, and the requirements for LED lead frames are also moving toward high power and low cost. However, the price of LED lead frames produced by Changhua is It is higher, but it has an advantage in terms of efficiency and volume. In the future, it will also lock the first-line LED packaging manufacturers in Europe, America and Japan as customers.
EMC's appearance in the LED field immediately attracted countless attention. The high-power brackets of the 3030 used by domestic Tiandian, Nichia, Jufei and Ruifeng are the latest technology EMC bracket packages.
