PVA DELTA 8​ : High-Precision Automated Coating & Dispensing System

🧰 Introduction & Key Features

• The Delta 8 is an automated robotic system for coating and dispensing, designed to handle processes such as protective conformal coating, potting, bead and gasket dispensing, underfill, sealing, SMT adhesive application, solder paste dispensing, and more.

• It uses an overhead 3-axis motion platform (with an optional 4-axis upgrade supporting valve tilt and rotation), enabling multi-angle access to components and surfaces. The system is suitable for both inline production lines and batch-type operations.

• It supports a wide range of materials and applications—from light coatings, spray adhesives, potting compounds, and gasket materials to SMT adhesives, underfill materials, epoxies, silicones, and various industrial fluids.

• The system includes an onboard PC with PVA’s dedicated PathMaster® programming software, allowing unlimited program storage and the ability to import images for accurate path creation—resulting in faster programming, higher precision, and easy process reuse.

🔧 Applications & Suitable Processes

The Delta 8 can be used for a wide variety of dispensing and coating operations. Below are the key applications:

• Conformal Coating: Applying protective coatings to PCBs—either full-board or selective areas—to prevent moisture, dust, and corrosion while improving environmental durability of components.

• Dam & Fill: Creating a high-viscosity dam around components or circuits, then filling the inside with a lower-viscosity material. This method is ideal for thick protective layers and structural reinforcement.

• Encapsulation & Glob-Top: Dispensing epoxy or silicone to fully encapsulate sensitive component areas such as flip-chip or wire-bond regions, providing protection against shock, vibration, moisture, and contaminants.

• Potting: Filling electronic housings or modules with epoxy/silicone/urethane to protect circuits from environmental exposure and mechanical stress, enhancing overall product durability.

• Gasketing & Sealing: Dispensing liquid gaskets or sealants into grooves, joints, or flanges to create airtight and watertight seals—commonly used for enclosures, covers, and industrial equipment.

• Surface-Mount Adhesive / Solder Paste / Epoxy Dispensing: Accurate placement of SMT adhesives, solder paste, and epoxies for securing components, especially those with tight tolerances or very small footprints.

• Thermal Interface Material (TIM): Dispensing thermal pastes or adhesives between chips and heatsinks to enhance heat dissipation in electronics, refrigeration systems, LED modules, and similar devices.

• Underfill: Dispensing underfill materials beneath BGA, CSP, and similar packages to improve mechanical strength, thermal cycling resistance, and overall reliability.

Thanks to its high flexibility, the Delta 8 can be customized for unique production needs—multiple valves, multiple material types, and a wide range of job configurations—making it ideal for high-mix or diverse manufacturing environments.
