SPRAY COATING SERIES
Spray application of a conformal coating requires the use of High Velocity Low Pressure (HVLP) spray technology that is standard across all Gen3 Systems spray coating machines.
All Gen3 Systems spray coaters can also be equipped with an automatic material and solvent feed that minimises on-site material handling; and intrinsically safe (ExD) light fittings that employ either (or both) white and UV light sources can be specified.
The model SB2900 has been specially designed for the application of conformal coatings to Printed Circuit Assemblies (PCAs) by batch spraying. It features an ergonomic design to minimise operator fatigue, while providing greater control of the spray gun position and direction. This limits overspray and unnecessary material wastage.
The SB2900 can be equipped with explosion-proof UV light and/or white light and employs a hands-free, rotating table for total 360° visual inspection.
The spray chamber also has a restricted opening and downward extraction plenum chamber, thus limiting operator exposure to solvent vapour. To ensure optimum filtration efficiency, the primary, secondary and tertiary filters are all easily replaceable.
A standard 10-litre pressure pot feed system can be supplied with pre-blended material to minimise filling downtime, along with semiautomatic purging and cleaning of the spray head.
An integrated storage space beneath the booth is provided for material and purging solvent pressure pots, the spray gun and facemasks etc.
The SB2900 is specifically designed to work with highly flammable materials.
SC 3000 Series are automatic conveyorised systems designed especially for conformal coating applications.
Able to apply coatings accurately down to a coating thickness of only 200µM, they also lend themselves to other precision coating requirements such a photo-resists.
They employ a multi-gun spray zone that may be followed by an optional UV inspection station, and in-line curing oven. Designed and built specifically to handle highly flammable materials, they incorporate automatic material and separate solvent feed via a volumetric metering pump.
The SC3000 Series are custom-built systems.
