Manufacturers of printed circuit boards use Glenro conveyor dip coaters with integrated infra-red dryers to increase throughput of printed circuit board manufacturing operations.
The Glenro Model 4246 dip coater and infra-red dryer system is designed to dip coat printed circuit boards in protective conformal coatings, and then dry the conformal coatings at rates between 50 and 500mm/min.
The conformal coating machine measures 2.2 x 2.5 x 1.6m.
A stainless-steel dip tank includes a recirculation and filtration system to maintain the quality of the conformal coating.
In addition, the system includes an optional controlling viscometer which automatically adds solvent to regulate the viscosity of the conformal coating, making for a more efficient line.
To keep the conformal coating clean and retard evaporation a cover for the dip tank is provided for when the machine is not in use.
A solvent fume exhaust system is included, as is a clean air input system.
All these features make the conformal coating machine more efficient for the customer thereby reducing production costs.
The conformal coating dryer section consists of a bank of six Glenro Radplane Series 36 low-temperature electric infra-red heaters, which are regulated in a single zone.
Aluminium reflectors keep the heat in the processing zone for greater energy efficiency and personnel safety.
The infra-red heaters' total connected power is 18kW.
The controls for the conformal coating machine are housed in a NEMA 12 enclosure and include a SCR temperature controller with push-to-read set point and emergency stop functions.
The control system also includes a purge timer for purging the conformal coating machine before startup.
An optional fire protection system is available.
Again, these features allow the customer to have a more efficient line.
As with all Glenro systems, the Model 4246 conveyor dip coating and infra-red drying conformal coating machine is constructed of heavy-duty materials for long, reliable service life.
Glenro conformal coating systems are shipped prewired reducing installation and line downtime costs to customers.
