Jesen independent research and development of metal substrate production equipment, the introduction of SF contouring technology, used in all kinds of light strips, can improve material utilization-free model, improve customer production efficiency. Self-developed thermal soft board material and technology, can be applied to high-power lighting of a variety of shapes. COB Our products have more than 5 years experience in development and production, mirror polishing technology globally unique, specular reflectance of up to 97%, a line yield up to 99.9%; otherwise COB process and develop a number of patented technology features: use prepregs improve the high thermal expansion coefficient of thermal conductivity of the upgrade problems caused by bending and twisting excellent durability, corrosion resistance, good dimensional stability and wear applications: LCD, LED, BLU, power supplies, converters, inverters car ignition car controller, voltage regulator converters, motor drives, PDP, audio and the like.
