UV Inspection Booth
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.
The DC 2000 NANO is a small, laboratory batch coating system designed for the high precision application of conformal coatings and photo-resists onto substrates by dip coating.
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.
As all approved conformal coatings contain a UV tracer, the coating glows bright blue under the UV light source, making inspection simpler and more effective.
The unit is constructed from a chassis of aluminium panels, with a solvent-resistant painted finish. An LED UV lamp is mounted inside the top panel on a pivoting bracket. This allows the operator to adjust the angle of the light to ensure their eyes are protected from the emitted UV light for maximum safety.
The DC 2000 NANO is ideally suited to low volume producers and can be easily adapted to run with many different types of coating.
An anti-static mat complete with anti-static earthing points is supplied fitted to the workbase, and an exhaust spigot is located centrally to the rear panel for connection to an external exhaust duct. The spigot measures 25 x 80 mm in diameter. Lamp life is approximately 25,000 hours.
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.
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 UV Inspection and Rework Booth is designed to assist in the inspection, repair and/or reworking of conformally coated electronic circuit assemblies.
SB2900 Spray Booth
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.
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 NANO - COAT Dip coating systems are designed for a variety of ultra precision application of coatings from <60nm to >50μm at >3% accuracy. Being totally air operated the Nano-Coat Dip Systems are totally safe to use with all coatings including flammable liquids and for the very widest range of applications.
An integrated storage space beneath the booth is provided for material and purging solvent pressure pots, the spray gun and facemasks etc.
Dip coating is the most effective method of applying a conformal coating whether in terms of efficiency, productivity or cost. High volume manufacturers design their assemblies so that any component that should not be coated (e.g. connectors, trimmers, presets, switches) are located on one side of the assembly.
The SB2900 is specifically designed to work with highly flammable materials.
DC 2000 NANO-COAT Dip Coating
A pneumatic air-over-oil system ensures that the substrate carrier exhibits a smooth "judder-free" motion during the immersion and withdrawal strokes. Its speed can be adjusted with great accuracy to suit the viscosity of a wide range of materials. This produces an extremely smooth and even finished coating result.
