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.
