Standard Automated Dip Coating and Drying Systems

Glenro designs and manufactures conveyorized machines that vertically dip coat and submerge printed circuit boards into protective conformal coatings and then dry the coatings. One machine: one continuous process: one operator.

Dip coating both sides of the product at the same time promotes high-quality encapsulation of the components and increases through-put. Dip coating eliminates the need for complicated material handling systems, multiple operators, and avoids the high maintenance of spray coating equipment. End users are attracted to the idea of dip coating their boards, as compared to spray coating because dip coating reduces the overall cost of manufacturing. Very little coating is wasted and specified coating thicknesses required to protect the boards against the end-use environment in which they are designed to operate can be applied and dried in one pass through the machine. Dip coating with set-point viscosity control puts the user back in control of the commercially available conformal coatings and allows operators to extend the coverage areas per gallon purchased.

Standard Features:
Preassembled & Wired
Stainless Steel Dip Tank, overflow reservoir, liquid level control to +/-50 mils
Recirculation-Filtration System, to maintain the quality of the coating
Supply and Exhaust Air Ventilation, to maintain a safe operation
Speed Controlled Driven Conveyor, with cross bars to hang the work
Low Temperature, Uniform Infrared Dryer
Control System

Optional Features
Controlling Viscometer, inclusive of indicating meter, solvent reserve tank and additional control piping and wiring
Fire Suppression System, designed in accordance with the National Fire Protection Association, Pamphlet No. 12
Dip Tank Nitrogen Purge Blanket, which includes a tank cover with fitting for connection to a remote N2 supply to deter coating evaporation when the equipment is not in use.

Model 4124

Model 4124 is an automated vertical conveyorized dip coat and infrared drying system. The conformal coating machine is capable of handling a working part area up to 20 inches wide and 10 inches in the dip direction. A typical production rate for this machine, given a 6 inch square board would equal 72 boards per hour at a conveyor speed of 4 inches per minute.

This standard design comes preassembled and wired. It includes a dip tank and an overflow reservoir with liquid level control to +/- 50 mils, recirculation-filtration system, infrared dryer, ventilation equipment, driven conveyor and a control system.

The machine illustrated was also equipped with a controlling viscometer and fire suppression system.

Model 4246

Glenro Model 4246 is designed to dip coat printed circuit boards in protective conformal coatings, and then dry the conformal coatings in one operation using one operator. A typical production rate for this machine, given a 6 inch square PCB would equal 144 boards per hour running 4 inches per minute.

This standard design comes preassembled and wired. It includes a dip tank and an overflow reservoir with liquid level control to +/- 50 mils, recirculation-filtration system, infrared dryer, ventilation equipment, driven conveyor and a control system.

The system illustrated was also equipped with a controlling viscometer and fire suppression system.
