PVA Selective Conformal Coating Jet Head (Controls Not Included)
PVA SJ100 — Selective Conformal Coating Jet Head (Controls Not Included)
The PVA SJ100 is a selective conformal coating jet head designed for non-contact, precision dispensing of conformal coatings on PVA selective coating and dispensing systems. The SJ100 delivers controlled, repeatable coating deposits without physical contact with the board surface, making it ideal for coating complex PCB layouts with tall components, keep-out zones, and tight tolerances. Controls are not included and must be ordered separately or used with a compatible PVA control system.

- Repeatable deposit control — consistent coating volume and placement for process-controlled production
- Compatible with PVA systems — integrates with PVA selective coating platforms for automated production
Frequently Asked Questions
What controls are required for the PVA SJ100?
The SJ100 jet head requires a compatible PVA control system to operate. Controls are not included with the SJ100 and must be purchased separately. Contact MTE Solutions to confirm which PVA control unit is compatible with your system configuration.
What is the difference between a jet head and a spray valve for conformal coating?
A jet head like the SJ100 uses non-contact jetting to deposit precise, controlled amounts of coating fluid without touching the board. A spray valve atomizes fluid into a fan or cone pattern. Jet heads provide greater precision for selective coating with tight keep-out zones, while spray valves are better suited for broader area coverage at higher throughput.
What conformal coating materials is the SJ100 compatible with?
The SJ100 is designed for use with standard conformal coating formulations including acrylic, urethane, silicone, and epoxy coatings. Fluid viscosity and surface tension affect jetting performance — contact PVA or MTE Solutions to confirm compatibility with your specific coating material before use.
Can the SJ100 be used for other fluids besides conformal coatings?
The SJ100 is optimized for conformal coating applications on PVA selective coating systems. For other fluid dispensing applications (adhesives, fluxes, encapsulants), PVA offers other jet and spray valve configurations. Contact MTE Solutions to discuss the right valve for your application.
Is the SJ100 sold individually or as part of a kit?
The SJ100 is sold as an individual jet head without controls. Contact MTE Solutions for current pricing, lead times, and compatible control system options.
