| Now, along with the rapid development of the integrated circuit industry, ICpackaging equipment are constantly updated. Automatic bonding machine as a key leadone of the sealing equipment, lead bonding technology is put forward the ordeal.SDW35(The Japanese company product code) wire bonding machine is set precisionmachinery, automatic control, image recognition, optical, ultrasonic welding technologyin one of the modern high-tech production equipment, is currently the mainstream leadbonding equipment. But because the chip on the market at present manufacturingtechniques in chip ward, the surface texture and color is not the same, SDW35bondingmachines themselves lead light effect cannot fully satisfy the demand of bonding,leading to some type of chip can’t identify effective, easy to produce the leak, wrongwelding and welding a series of related scrap, at the same time appear MTBA(MeanTime Between Assistance)smallã€qualified rate lower phenomenon. In this case, theurgent need for a more suitable light effect. This article through to SDW35wirebonding machine the original light source system research, combining modern LEDtechnology, design a kind of new light source system to meet its light effect. And afterthe experiment proved to be feasible.The object of this research is the SDW35wire bonding machine light effects.Thisthesis briefly introduces the SDW35wire bonding machine working principle and itslight source system principle of work, and then analyzes the current semiconductorindustry other wire bonding type light source the advantages and disadvantages of thesystem, but also analyzed the current SDW35wire bonding machine source systemmalpractice and improvement of significance.According to the original SDW35wirebonding machine source system existence malpractice and MTBA small, low qualifiedrate, replacement cost characteristics, combined with the other semiconductor wirebonding type light source system advantages, in the third chapter introduces new lightsource system design and specifications. The last part is the experimental data andconclusion part, verified by new light source system economy and applicability. Thistopic design concept is the use of LED arc light emitting device (LED arranged in arc) instead of the original light source system. Use this way there are several advantages:one is the significant increase in light effect, improve image recognition ability; Two isto improve the quality of products and MTBA; Three is to reduce defective products orimprove the qualified rate of the product; Four is to improve the profits, the costsavings. |
