Traditionally, the major market for conformal coatings has been the defence electronic industry where the need for long-term, high reliability demanded the presence of environmental, electrically-insulative coatings. Conformal coatings can be formulated from many different chemical technologies and are normally applied by dipping, spraying, or flow coating processes. The cured coatings are chosen based on their dielectric properties, abrasion, solvent and thermal resistance, and ease of application.

At Nemco we have two purpose built, ventilated Conformal Coating rooms, one used for the application of Silicon material and the other for Acrylics. Each of these rooms contain their own spraying equipment machinery, tooling and material storage. During the process, Dry Coating Thickness Tests are performed using a Positector 6000 Micron Measuring System and Coupons. Before coating the boards it is important to determine the dry thickness requirement via the Customer. Typical IPC standards for coating dry thickness are 50 – 210 Microns for Silicon and 30-130 Microns for Acrylic. 

Each Room contains their own Inspection equipment along with UV Lighting. This aids the Operator when inspecting each board after coating has been applied.

Selective Spray coating

The Acrylic Room contains a Nordson Asymtek SL940 Selective Spray Coating Machine which is designed to provide the highest quality and productivity for automated coating processes. It provides consistent, uniform dispensing of conformal coating materials for conveyorised applications. The SL-940 is a high-speed, high-accuracy conformal coating system with an integrated, closed-loop process control that ensures superior coating quality. Process parameters are recorded and traceable through Easy Coat (ECXP) software. The system can eliminate the requirement for labour-intensive board masking, providing accurately controlled patterns, film builds and production flexibility in an automated process. Film thickness is achieved in a single pass with little or no masking and with virtually no overspray.

The Silicon Room contains a PVA2000 system which provides a clean, efficient process for applying conformal coating while virtually eliminating masking operations. Utilizing a controlled atomized spray and a non-atomized flow coating process, the PVA2000 limits conformal coatings to a defined, pre-programmed coverage area. Film builds as low as 0.01mm (0.0005”) can be achieved across the desired surface. The PVA2000 offers an unparalleled level of precision and speed to the coating.

Materials Used

  • Humiseal 1B31 & 1B73
  • Electrolube HPA
  • Acota Certonal Coating
  • Humiseal Thinners
  • Electrolube FSC
  • Electrolube DCA
  • DCR – Modified Alkyd Conformal Coating
  • Electrolube DCT Thinners

Certonal Coating (Dip)

Certonal coating is under taken via our Autocoat 1000 dip coating system which provides full immersion coating followed by a drying process in a frost free cooled area. The coating and drying process is contained within the same tank which is fitted with a user configurable filtration system. The basket is moved through the process chamber and dwells at the relevant process stages, controlled by the integrated logic controller and fully adjustable utilising the touch screen. The Certonal protective coating offers an effective protection of electronic devices against failures that are caused by condensation or air humidity, providing increasing dependability of products that are exposed to disadvantageous environmental conditions. The environment-friendly and effective dipping process does not require any masking on contact areas; keeping contacting ability and functionality of coated components on the other hand. The transparent and UV stable coating with only 1 μm thickness has no impact on optical components and offers a long-lasting life span.Materials:

RDC 15 (Dip) FSC Coating

The RDC 15 Dip Coater with Stepper Motor Control has a variety of speeds and settings. The Features of this system are:

  • Lift bar for several workpiece fittings.
  • The dip coater works with constant dipping speed. This speed is adjustable between 30 – 10.000 mm/min. The drawing speed determines the thickness of the coating. This speed is as well adjustable from 30 – 10.000 mm/min.
  • The dipping time as well as the drip-off-time (pause time up and down) is separately adjustable from 0,5 s up to 100 hours. This enables the machine not only to coat but also to precisely develop.
  • Up to 9 iterations are possible.
