PVA Global, a world-class innovator of high-quality, repeatable dispensing and conformal coating systems, has introduced the Delta 6, a state-of-the-art flexible robotic conformal coating and dispensing system that promises to elevate selective coating, potting, bead, and meter-mix dispensing applications to new heights.

The Delta 6 showcases a robust overhead three-axis motion platform designed for both inline and batch operations. While retaining the favored features of its predecessors, the Delta 6 distinguishes itself with a slimmer footprint, enhanced structural and gantry rigidity for heightened robustness, and improved accessibility.

This cutting-edge system boasts an array of options and integrated features, including a remarkable robotic system repeatability of 25 microns. The Delta 6's patented servo-controlled optional four-axis motion, featuring valve tilt and rotation, sets a new standard for precision and flexibility in dispensing applications.

One of the key features of the Delta 6 is its closed-loop process control throughout the gantry system, ensuring optimal performance and accuracy. The system also supports multiple dispensing applications or materials within a single cell, providing a versatile solution for diverse manufacturing needs. The Delta 6 has an onboard PC for unlimited program storage and utilizes the exclusive PathMaster programming environment, streamlining the programming process for enhanced efficiency.

Versatility in Action: Diverse Applications of the Delta 6

Conformal Coating: The Delta 6 excels in the application of protective films or liquid layers onto PCBs, offering precision through various technologies such as atomized spray, airless film, needle dispensing, and jetting.

Dam & Fill: Utilizing a two-step process, the Delta 6 dispenses high-viscosity fluid around the perimeter of electronic circuitry and subsequently fills the area with low-viscosity fluid to fully encase components, ensuring optimal protection.

Encapsulation & Glob Top: This application involves applying epoxy or silicone-based fluid to cover specific areas around flip chips or wire-bonded components, providing mechanical stability and protection against environmental factors.

Gasketing: The Delta 6 automates the form-in-place gasketing process, dispensing liquids into grooves or onto flanges to form seals against liquids and gases, eliminating the need for pre-made gaskets and allowing for easy geometry modifications.

Potting: In the potting process, the Delta 6 fills enclosures holding electronic circuitry with a liquid that, when cured, encases the unit, offering mechanical stability and protection against environmental elements.

Surface Mount Adhesive/Solder Paste: For accurate deposits, the Delta 6 excels in dispensing surface mount adhesive, solder paste, and filled epoxies critical for bonding SMT components to PCB surfaces.

Thermal Interface Materials: The Delta 6's precision is evident in filling gaps between mating surfaces with thermal interface materials, improving thermal conductivity, and enhancing heat transfer.

Underfill: The application of fluid along electronic component edges prevents thermal mismatch, and moisture penetration, and provides stability during shock and vibration.

PVA Global's Delta 6 emerges as a game-changer, setting new standards for flexibility, precision, and efficiency in conformal coating and dispensing systems. Manufacturers can now benefit from a versatile solution that meets the diverse needs of modern electronic manufacturing processes.
