Automated Fluid Dispensing Automated Fluid Dispensing SystemSystem

Printed circuit boards (PCBs) are becoming ever more complex and assemblies are being packed with an ever-greater component density and SMT components that get exposed to harsh and rugged environments.



Typical coating methods are not equipped with the precision or speed to handle applying conformal coating to these type of assemblies.



Coating machine equipment Coating machine equipment manufacturers are manufacturers are constantly developing better constantly developing better process control tools, process control tools, software, equipment and software, equipment and coating compounds in coating compounds in response to this need.response to this need.



Customer demands and Customer demands and emerging technology have emerging technology have led to the adaption of led to the adaption of archaic conformal coating archaic conformal coating equipment to automated equipment to automated fluid dispensing systems fluid dispensing systems that can better answer this that can better answer this need. need.



Adaptations of dispensing Adaptations of dispensing valve applicators, fitting of a valve applicators, fitting of a high-speed fluid dispenser high-speed fluid dispenser to coating machines, and to coating machines, and advancements in conformal advancements in conformal coatingcoating compoundscompounds are just are just some of the technology that some of the technology that has allowed the manufacture has allowed the manufacture of advanced electronics.of advanced electronics.


Four-Axis Tilt ActionFour-Axis Tilt Action

Fluid dispensing equipment Fluid dispensing equipment that has the capability of that has the capability of flow coating and outlining flow coating and outlining the No-Zone or sensitive the No-Zone or sensitive areas are aided by the areas are aided by the pneumatic four-axis tilt pneumatic four-axis tilt action during the process in action during the process in coating machines. coating machines.



In the past, conformal In the past, conformal coating machine dispensers coating machine dispensers could not coat the bottom or could not coat the bottom or sides of components on sides of components on PCBs, however, that PCBs, however, that restriction was lifted with restriction was lifted with the advent of four-axis tilting the advent of four-axis tilting capabilities. capabilities.



They are now equipped with They are now equipped with a tilt accessory on the arms a tilt accessory on the arms to coat all four sides of the to coat all four sides of the component and areas that component and areas that previously could not be previously could not be reached with the traditional reached with the traditional vertical approachvertical approach..



The vertical angle of the The vertical angle of the dispenser can now be tilted dispenser can now be tilted to about 35° maximum in to about 35° maximum in most machines and hit the most machines and hit the right, left, back, or front of right, left, back, or front of difficult-to-reach areas and difficult-to-reach areas and components. components.



Four Position Tilt Four Position Tilt capabilities allow the capabilities allow the machine to coat all the sides machine to coat all the sides of a component with of a component with precision. precision.


Five-Axis Tilt ActionFive-Axis Tilt Action

Some coating machines Some coating machines have a five-axis tilt have a five-axis tilt application that allows for application that allows for further functionality for the further functionality for the fluid dispenser and has tilt fluid dispenser and has tilt and rotation activities for and rotation activities for dispensing conformal dispensing conformal coating on vertical services coating on vertical services and underneath the and underneath the components. components.

The dispensing action can The dispensing action can gain access in tight and gain access in tight and hard to reach areas that are hard to reach areas that are impossible to coat with a impossible to coat with a standard downwards spray standard downwards spray pattern. pattern.


Coating Specifications and More Coating Specifications and More FunctionalityFunctionality

The conformal coating for The conformal coating for PCB advancements has PCB advancements has allowed for many desirable allowed for many desirable specifications. specifications.



The spray coating patterns The spray coating patterns of automated fluid of automated fluid dispensing systems usually dispensing systems usually vary from about 0.125” vary from about 0.125” (3.175 millimeters) to about (3.175 millimeters) to about 2” (50.8 millimeters) and the 2” (50.8 millimeters) and the variation is attributable to variation is attributable to the height of the dispenser the height of the dispenser from the substrate. from the substrate.



You can easily achieve You can easily achieve thicknesses of 0.002 " (0.051 thicknesses of 0.002 " (0.051 millimeters) and beyond millimeters) and beyond with a single pass of the with a single pass of the dispenser. dispenser.



The thickness of the coating The thickness of the coating is controlled by the machine is controlled by the machine speed and the flow regulator speed and the flow regulator located on the spray valves. located on the spray valves.



Conformal coating machines Conformal coating machines have evolved to be able to have evolved to be able to coat vertical parts and hard coat vertical parts and hard to reach areas by using to reach areas by using innovative tilt functions and innovative tilt functions and optional needle systems as optional needle systems as needed for conformal needed for conformal coating pcb assemblies.coating pcb assemblies.



When procuring a fluid When procuring a fluid dispenser system for your dispenser system for your facility, it is critical that all facility, it is critical that all facets of the required facets of the required access of motion are access of motion are considered, evaluated, and considered, evaluated, and matched toward what you matched toward what you are trying to achieve for are trying to achieve for your business needs. your business needs.



It is also critical to explore It is also critical to explore the necessary axes of the necessary axes of motion required to meet motion required to meet your objectives in order to your objectives in order to have a successful outcome. have a successful outcome.
