Scrubbers

This system simultaneously scrubs and cleans both sides of printed circuit boards and metal panels.

Conveyor

The conveyor rollers are constructed of a three piece design. Brass end plugs are machined and pressed into a steel tube. Neoprene rubber is then blown over the tubes forming a rigid yet resilient conveyor roll that is impervious to moisture and most chemicals, yet will not damage the most delicate of circuit boards.

Brushes

Each brush is powered by an independent motor through a banded V-belt drive.

Brush adjustment is accomplished by a mechanical micro precision control, coupled to the bearing housing sides. This allows the brush pressure to be independently varied to ensure a balance between top and bottom scrubbing. This precise control is monitored by two visual load indicating ammeters.

The brushes have a positive mechanical coupling, driven by a high torque gear motor, causing the brushes to oscillate 180° out of phase. This system eliminates the possibility of the phase balance being disturbed which would place undue stress on the machine.

The quick change brush system enables both upper and lower abrasive wheels to be changed in less than 15 minutes. The machine is designed to accommodate most industrial brushes.

The bearing housing utilizes a precision designed splined shaft and sleeve for a positive brush torque transmission.

The back-up rollers are manufactured of stainless steel and flame coated for extended life. The upper roller is self adjusting to compensate for the panel thickness. The lower roller supports the bottom of the panel and is firmly mounted to provide zero tolerance

The top and bottom brushes have brass spray nozzles (12 each for 24" wide systems, and 15 each for 30" wide systems) to cool both brushes and panel.

Rinse Section

The rinse section consists of four spray bars with strategically placed "High Pressure Jet Spray Nozzles" (15 top and 15 bottom for 24" wide systems, and 19 top and 19 bottom for 30" wide systems) which are designed to provide a positive overlapping rinse pattern. This assures complete rinsing and removal of loose particles from both panel surfaces and barrels of drilled holes.

Drying System

An efficient, filtered air system is the key to the drying principle. A high velocity pressure type self cleaning aluminum fan produces 1450 cubic feet of air per minute at 15 inches of static pressure. Ambient air is then fed through six uniquely designed airknives (three top and three bottom) that blast away any trace of moisture, including all through holes.

Other key features are:

• The frame is constructed of welded angular steel and coated with high quality chemical and rust resistant paints.
• The precision machined frame plates are fabricated of high impact stress relieved polyvinyl chloride and connected by heavy duty stainless steel bars to ensure positive warp resistant construction.
• External covers are constructed of 1/4" PVC to withstand the most rugged abuse. They are custom fitted to obtain a streamlined finish.
• Variable speed conveyor for precise process control and smooth positive roller action.
• Optional variable speed brush oscillation.
• Optional high pressure rinse system to 1,200 psi.
• 24" and 30" wide models available.
• Process parts 2"-24" in width, and 6" or longer in length.
• Process parts 0.01" to 0.25" in thickness. 0.004" to 0.25" thickness with optional thin film guide system.
• Control switches and indicators are conveniently located on the front of the machine.
• Optional remote electrical control panel.
• Low water usage which reduces operating costs.
• Optional closed loop filtration system which removes particulate contaminates such as copper. Since this is a closed loop system, external water is not required which further reduces operating costs.
• Optional thin film guide system.
• Domestic and export power.
