Benchtop Coating/Dispensing System The Sigma benchtop is a compact three-axis robotic gantry ideal for automating a variety of dispensing and coating applications. Featuring multiple mounting positions, users can easily incorporate multiple chemistries or application techniques into their process. With remote programming capability and image background import, programs can be quickly uploaded from your desktop utilizing Sigma’s internal 2.4 GHz Wi-Fi network. Sigma combines PVA’s superior quality and global support in a flexible, multi-purpose robot that instantly brings repeatability to your manufacturing process. The Sigma benchtop has many options and integrated features including: 5-inch touch interface with Wi-Fi connectivity Offline G-code numerical control programming Enclosed work area with safety interlock Single or dual valve mounting positions Standard jig plate mounting surface Conformal Coating The application of a protective film or layer of liquid onto a PCB, either in selected areas or over the entire assembly. Conformal coatings are applied using an array of technologies such as atomized spray, airless film, needle dispense and jetting. Dam & Fill 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. Encapsulation & Glob Top Applying an epoxy or silicone-based fluid that completely covers a defined area around a flip chip or wire bonded component.
