Selective Conformal Coating systems SimpleCoat and SimpleCoat TR are ideal for selective conformal coating and dispensing applications that require a high level of accuracy and repeatability, both for medium and low volume production. A stand-alone configuration is available for manufacturing that does not require a conveyor.

Some applications require coating on products with a complex geometry. For these types of products, a standard top-down coating may be insufficient. The tilt and rotate model - SimpleCoat TR - allows the spray valve to be tilted ±45° and rotated ±90° to reach four sides of a product.

Equipped with a robust 3-axis motion platform that, in the base configuration, includes spray valve and a needle valve; an optional volumetric pump may be used in place of the needle valve.

SimpleCoat works with a laptop computer. Programming is easy and can be done either by manually teaching a program or by using a JPG image of a PCB. All parameters, such as valve parameters and motion parameters, can be easily altered. Various shapes, patterns, and areas can also be programmed.

A Tilt and Rotate head is included in the base configuration of the SimpleCoat TR along with the robust 3-axis motion platform. Station 1 spray valve tilts ±45° and rotates ±90° giving you full access to all sides of your device.
