Glenro is a leading manufacturer of conveyorized dip coating machines that vertically submerge printed circuit boards into protective conformal coatings. Our dip coaters are designed for high-quality encapsulation of components and increased through-put. Dip coating eliminates the need for complicated material handling systems, multiple operators, and high maintenance spray coating equipment. End users prefer dip coating because it reduces overall manufacturing costs. Our machines allow for very little coating waste, 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. 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.
Our standard dip coater features a preassembled and wired system with a stainless steel dip tank, overflow reservoir, liquid level control, recirculation-filtration system, and supply and exhaust air ventilation for safe operation. The speed-controlled driven conveyor with cross bars to hang the work, low temperature uniform infrared dryer, and control system are all included. Optional features include a controlling viscometer with an indicating meter, solvent reserve tank, and additional control piping and wiring, fire suppression system designed in accordance with the National Fire Protection Association, and dip tank nitrogen purge blanket with a tank cover and 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.
