[Text / Gaogong LED reporter Zhu Chunwei] From November 25th to 27th, the 2013 Gaogong LED Lighting Exhibition held by Gaogong was held in Guangzhou Poly World Trade Center Expo. Nearly 200 well-known brand manufacturers at home and abroad participated in the exhibition. Grid code as a representative of welding consumables was invited to attend the exhibition, and with this opportunity to fully demonstrate the strength of ICP code and new products and technologies.
Founded in 2008, Sigma Technology has been deeply involved in the development and application of precious metal materials. The purity of the evaporated gold Au Slug developed by the company is 4N~5N, and the purity of the pure gold wire GW SCL/SCD is not only 99.99%, but also the line. The diameters range from 16μm to 50μm, and can be customized according to customer's requirements.
“Whether gold wire, alloy wire or wire wire is used, the cost difference is still very obvious. The gold wire with high purity is generally around 500 yuan/pcs, the alloy wire is about 350 yuan, and the iron wire is cheaper.†Yin Shuyuan, director of Sigma Technology Co., Ltd., said that the gold wires used in early LED packaging were mostly made of Au material bonded with a purity of 99.99%, which mainly played a role of a wire to make the chip energetically.
Among them, in the packaging process, the choice of wire material is directly reflected in the manufacturing cost of the lamp bead.
The gold wire has the advantages of high electrical conductivity, corrosion resistance, oxidation resistance, etc., but the biggest disadvantage is that it is too expensive. Inconsistent with the trend of the overall price of LEDs, people began to look for some gold wire substitutes or directly remove the gold wire design.
At the same time, in order to meet the needs of different levels of customers, Sigma has also introduced some alloy wire products, including AW SF/SH/SK models of Sigma alloy wire and CW/PC/PAW of Sigma film coating line. At the same time of work stability, reduce the dead light rate of the product and reduce the cost of the package wire.
