PVA Delta 6 Conformal Coating and Dispensing Machine

The Delta 6 is suited for selective conformal coating, potting, beading/dispensing, and meter-mix dispensing applications. It supports multiple materials and types of fluid applicators in one cell.

It delivers an XYZ repeatability of ±25 microns (0.001″) using a closed-loop gantry with brushless DC servo motors, ball screw slides, and optical encoder feedback. Resolution is 5 microns (0.0002″).

For one valve/tool, the work area is approximately 521 × 485 × 101 mm (L × W × Z). This gives moderate coverage for board sizes typical in conformal coating or dispensing.

The machine supports a broad range of applicators including spray valves (e.g. FCS-series), dispense valves, jetting, auger, progressive cavity valves, etc. Fluid feed options include syringe (1-55cc), cartridges (6-20 oz), pressure vessels, drums, or totes.

It supports conveyors (flat belt or chain), board widths from 50 mm up to 500 mm. Top and underside board clearance are both approx 80 mm. Edge clearance is ~4.7 mm. Transport height is ~940-965 mm. Communication via SMEMA and options for board support (lift-locate, pins, etc.) are available.

Maximum XYZ speed is about 670 mm/sec (≈ 26-27.6″/sec) with acceleration up to 0.5 g. These motion specs enable faster coatings/dispensing operations while maintaining precision.

The footprint is about 847 × 1,136.9 × 1,606 mm (W × D × H). It operates on 120V or 220V, 50-60 Hz. Air supply required is 80 psi, dry and unlubricated.

The Delta 6 uses PVA’s PathMaster X® programming environment which allows offline image import, storing unlimited programs, barcode-based program selection, closed-loop material flow monitoring, low fluid level sensors, and onboard PC control. These help reduce setup-time, enable repeatable dispensing/coating, and reduce downtime or errors.
