In recent years, LED epitaxy and chip technology, phosphor preparation and use technology and high thermal conductivity bracket technology have developed rapidly, and there are new trends in the field of SMD packaging:
1. High current drive: Under the same chip size package condition, use more current drive to get more light output.
2, high power: traditional medium / small power SMD package products under high current drive, product power is improved, luminous flux and light efficiency are improved, the overall performance is more stable.
3, medium / large size: In the patch packaging market, the most active is the medium size patch package, concentrated in SMD2835 and SMD3014, the large size SMD5050 is also beginning to be active.
4, high thermal conductivity bracket: new thermal conductive material and thermal conduction bracket, so that more heat can be transmitted faster to ensure the reliability of led light source .
5, the demand for higher light quality: At present, the quality requirements of indoor lighting for light sources are getting higher and higher, the color rendering index is 80 is the standard product, the color rendering index is 90 is the target product of future development, the light color requirement is close to the Planck curve. The color tolerance tends to the MacAdam ellipse, while requiring uniform light, no glare and ghosting.
Dow Corning OE6662 advantages in the SMD packaging market
A new trend in the LED chip packaging market, as the world leader in silicone, silicon technology and innovative silicon products, Dow Corning's latest OE6662 silicone packaging materials have attracted the attention of the industry, which has the following excellent performance:
1. High hardness: to ensure the customer's requirements for the hardness of the packaged product, the moisture permeability and oxygen permeability will be lower, and the product's resistance to vulcanization will be improved. The difference from the competitor is that Dow Corning does not introduce a heterocyclic ring or epoxy in the product.
Ingredients to meet the requirements of hardness and moisture permeability, because it will significantly reduce the heat and UV resistance and life of the product.
2, high luminous efficiency: As a 100% silicone material, OE6662 has excellent thermal performance and optical stability, as well as excellent UV, chemical and cold resistance, to ensure more stable throughout the life of the lamp, Reliable, high-quality light output enhances the light efficiency of the product.
3, high temperature resistance: As the product uses high current drive and medium size package, the LED light source has a higher operating temperature, such high temperature will cause yellowing of the packaging material containing heterocyclic or epoxy components during long-term use. Physical degradation. OE6662 silicone materials still exhibit reliable optical and physical properties at temperatures approaching or exceeding 180 °C.
4, high cost performance: OE6662 is 100% silicone material, with more outstanding performance and longevity to help customers reduce costs and improve product market competitiveness.
Shenzhen Kaism Technology Co., Ltd. successfully promoted the OE6662 case
As the largest partner of Dow Corning Electronic Industrial Products in China, Shenzhen Kaishm Technology Co., Ltd. not only provides customers with high-end LED packaging materials, thermal conductive materials, and related equipment, but also provides professional consultation in product selection and application. Service, while sharing the successful experience of new material applications with customers.
1. SMD2835 package success case (Shenzhen, H Company, Guangdong)
At present, SMD2835 adopts high-current driving and heat-dissipating heat dissipation to ensure high brightness and high quality. The innovation of the package structure brings great challenges to the packaging materials. The traditional low refractive index, high current impact resistance, poor temperature resistance of epoxy resin, silicone modified epoxy resin and silicone material Can not meet the needs of customers. OE6662 has a refractive index of 1.54, which guarantees high light output and stable luminous flux. The hardness is ShoreD65, the product's resistance to vulcanization is significantly improved, and the moisture permeability is significantly reduced. The temperature range is -40 ° C to 180 ° C. The temperature resistance of the product is improved. The customer preferred OE6662 as the packaging material of SMD2835, which not only guarantees the quality of LED light source, but also wins a good reputation for the enterprise.
2, SMD3014 packaging success case (Guangzhou, Guangzhou, A company)
SMD3014 is currently the most popular LED packaging product. Customers in the process of using silicone modified epoxy resin packaging materials often have problems such as high temperature and yellowing, increased luminous flux attenuation, and increased product defect rate. In order to completely solve this problem, the customer introduced the OE6662 product in the SMD3014 production line, combined with the LED packaging technology solution provided by Dow Corning and the high-quality sales service of Kaism, the product quality and performance gradually improved, and the market share of SMD3014 products increased steadily, sales obviously increase.
3, SMD5050 packaging success case (Guangdong Shenzhen, M company)
As we all know, SMD5050 products are prone to problems such as cracking and dead lights, which makes many packaging engineers have a big headache. In response to this problem, we specifically analyze the actual situation of the customer, specifically recommend M company to use OE6662 as the encapsulant, and provide customers with a complete set of Dow Corning silicone packaging solutions, especially for high-power drive high-power SMD5050 package products. The product's high temperature resistance and vulcanization resistance have been improved to a certain extent, which has improved the customer's product quality and market competitiveness.
Review
