Dam and fill encapsulation

WebDam and fill encapsulation is a similar process except that a high viscosity material is used to create a wall or dam around the component. This dam is then filled with a low viscosity polymeric solution. Glob top materials due to their relatively high viscosity are relatively slow to dispense and can cause problems in underfilling components. WebDam and Fill encapsulant uses a dam around the die area to control the encapsulant flow within a contained area. This process can result in a much flatter encapsulation profile. …
