Dam and Fill is a two-step process of first dispensing a high viscosity fluid around the perimeter of a device or electronic circuitry, and then dispensing a low viscosity fluid within the perimeter to fully encase the components. The dam can be applied as a single or multi-layer bead depending on the target fill height required.
A dam and fill process is ideal for encapsulating an area of components or a wire bonded die. This process can precisely control the wetted area of a PCB during this stage of assembly.
Using a silicone material during the process adds higher shock and thermal resistance than a conformal coating process.
PVA offers a wide variety of valves ideal for any dam and fill application.
