DC3000 In-line Dip Coating & Curing Systems
General Description
The DC3000 Series of in-line dip coating and curing systems are designed for the automatic application of conformal coating onto printed circuit assemblies at high production volumes of 350-700 per hour. These are "Custom Built" systems capable of handling any type of conformal coating including both new Water-Based and UV curable types.
Available in 2 principal versions:
DC3000 - Continuous running conveyor
(Low Capital Cost - Moderate Coating Consumption)
DC3005 - Indexing conveyor
(Higher Capital Cost - Low Coating Consumption)
The DC3005 system typically reduces coating consumption by more than 30% compared to continuous running conveyor systems.
They are specifically designed to handle highly flammable coating materials and incorporate all of the intrisic safety features demanded to comply with Health & Safety requirements.
They comprise a variable speed indexing conveyor with cross rods to which are attached suitable jigs or fixtures carrying the assemblies. The indexing conveyor automatically stops above the dip tank which is then raised and lowered at the pre-set immersion, dwell and withdrawal rates preselected for the substrate/material requirements.
The dip tank has standard dimensions of 1000mm (39") x 242mm (91/2") x 250mm (10") and is equipped with a constant recirculating pump system which will provide both repeatable uniform coating results and constant level precision dipping control. An inert gas (argon/ nitrogen) manifold is fitted inside the top of the tank to provide a barrier above the liquid to minimise solvent release and help maintain viscosity. A convection/IR oven zone is incorporated within the machine so that the coated boards are cured to a handling cured condition on return to the load/unload station.
The DC3000 basic system incorporates a continuous running, but variable speed conveyor. This system is fitted with a static tank measuring approximately 1000mm (39") x 650mm (26") x 250mm (10") and the assemblies are conveyorised through the dip tank and curing zone. This tank size is required to control the withdrawal speed by "rateof- rise" that demands increased tank surface area.
