ETS Launches New iCoat Series Conformal Coating Machines

Introducing the New iCoat Series, Selective Conformal Coating Robot

ETS Energy Technology Systems will begin rolling out a new generation of ANDA selective conformal coating machines called the iCoat Series for the North American market this coming October 2015. The iCoat Series is made up of three new coating machine models, known as the iCoat-X3, iCoat-Xt and iCoat-6. The new iCoat Selective Coating platform comes equipped with many new standard features to improve user operation and provide an exceptionally long factory life. A few of these new features include:

  • Robust frame design to cater for longevity and lasting machine accuracy
  • A lighter coating head design that enhances dispensing flexibility and durability
  • Optional pallet return conveyor under the iCoat machine to fully automate the coating line with our curing ovens and board handling equipment
Conformal Coating for Water Resistant Circuit Assemblies

Conformal Coating for Water Resistant Circuit Assemblies

Why Selectively Conformal Coat the Electronic Assembly?
Printed circuit boards (PCBs) are employed in a variety of products and devices, and this means that it might be necessary for your PCBs to be moisture resistant. It is important to choose the right type of conformal coating so you need not worry about the durability of your product. Fortunately, there are several options available that can help, and you can even use selective conformal coating robots to provide proper application of the coating.

Curing the Coating

When it comes to the application of conformal coating, curing the coating plays a key role in the circuit assembly and selective conformal coating process.

Curing conformal coating occurs after the coating spray/dispense process is complete. The coating is considered “cured” when the conformal coating on the circuit assembly is sufficiently tack-free to be handled. Curing can sometimes be accomplished at room temperature but takes a considerable amount of time to dry. Accelerated conformal coating curing decreases this drying period, the cure process reaches either the tack-free or a fully dried state but not quite having fully cured properties. Accelerated curing techniques include one or a combination of heat, moisture, UV light, and chemical reaction curing. This article focuses primarily on thermal or heat curing.

5 Axis Fluid Dispensing

Technology is in constant change and circuit assembly is no different. It is becoming more and more advanced as needs change and demands for more capabilities increase. In order to meet these demands, equipment manufacturers are integrating the latest innovations and tools to serve the industry. The need to better protect printed circuit assemblies from harsh environments using automated selective conformal coating is becoming a must. 5 axis fluid dispensing allows conformal coating to be applied to printed circuit assemblies like never before.

Measuring Conformal Coating Thickness

Measuring Coating Thickness

Achieving an even coat at the right desired thickness is a major challenge when it comes to applying conformal coating to a Printed Circuit Board (PCB). Applying a coating too thin will ultimately render the electronic assembly vulnerable to potential environmental risks therefore defeating the purpose of the coating. Apply the coat too thick, and it could leave the electronic specific components non-functional therefore destroying the electronic assembly entirely. Coating thickness must meet quality specifications. Measurements for coating thickness may be taken while film is dry or wet. Once measurements are recorded, thickness is compared to quality specifications and fluid dispensing automation machinery is calibrated as necessary. There are a handful of methods for measuring conformal coating thickness that are commonly used in the Electronic Manufacturing Services (EMS) and Original Electronic Manufacturer (OEM) industries. A few commonly used methods for checking conformal coating thickness include:
