H907-U底部填充胶 封装黑胶芯片保护 BGA芯片封装胶水环氧树脂 可返修快固化低粘度
H907-U是一种单组分环氧密封粘接剂,用于CSP或BGA底部填充制程及各类电子元组件、温度敏感产品、摄像头模组等之粘接固定、密封保护等。它能形成一致和无缺陷的固化胶层,能有效降低由于硅芯片与基板之间的总体温度膨胀特性不匹配或外力造成的冲击,具有较低之膨胀性。受热时能快速固化。较低的粘度特性使得其能更好的进行底部填充、元件粘接及产品密封保护等。

H907-u is a one-component epoxy sealing adhesive, which is used for the bottom filling process of CSP or BGA and the bonding, fixation and sealing protection of various electronic components, temperature sensitive products, camera modules, etc. It can form a uniform and defect free curing adhesive layer, which can effectively reduce the impact caused by the overall temperature expansion characteristics mismatch or external force between the silicon chip and the substrate, and has low expansion. It can cure quickly when heated. The lower viscosity makes it better for bottom filling, component bonding and product sealing protection.
