6'' 8'' 12'' UV Wafer Tape Curing System

In the semiconductor chip production process, the wafer shall be fixed on the frame with the wafer film before the chip scribing. After the scribing process is completed, LED UV light is used to illuminate the fixed film to make the UV film viscous curing and hardening, so as to reduce the viscosity of the scribing fixed film and facilitate the smooth production of the subsequent packaging process. In other words, UV tape has a strong adhesive strength that will hold the wafer firmly during the wafer grinding or cutting process. When the ultraviolet radiation, the bonding strength becomes low. As a result, the wafer or chip can easily peel off the adhesive tape after being exposed to ultraviolet light. UV Wafer Tape Curing System solves the curing process of wafer, glass and ceramic cutting technology, which is not only limited to semiconductor packaging industry, but also applicable to UV film curing of optical lens, LED, IC, semiconductor, integrated circuit board, mobile hard disk and other semiconductor materials. UV mercury lamp is commonly used in existing UV curing machines, but the mercury lamp light source with high heat emission is easy to damage thermal sensitive materials, with low efficiency and difficult to accurately control the quality standard, which is not suitable for the irradiation of high precision devices such as chips. The environmentally friendly low temperature LED UV light source curing machine adopted by Guangdong SpaceLight Technology Co., Ltd. can easily finish the UV film curing process without damaging the wafer, which can greatly meet the production requirements.
