Surface Coating for Electronics Applications


The number of times and places where we use technological technology is increasing all the time. Electronic products are omnipresent, from smartphones, tablets, and wearable gadgets to automation control and other professional tools. With the increasing popularity of electronic products, the use of electronic coatings has surged. It's critical to pick the right coating type and application procedure for your electronic devices.

Alfa Chemistry's surface coating technique may be used to a wide range of electronic surfaces and interfaces, resulting in exceptional performance, process simplification, and good value.

The Function and Application of Electronic Coating

Electronic coatings are components that help printed circuit boards, integrated circuits, and macroscopic devices improve their optoelectronic qualities. Conformal electronic coatings are polymer films that are used to protect printed circuit boards and integrated circuits from contamination and harsh circumstances. Although some electronic coatings offer physical benefits, their primary purpose is to improve the device's optical and electrical properties, such as anti-reflection, charge transfer, up-down conversion, electroluminescence, high refractive index, and photoinduced glow. To choose the most appropriate type for the component and its usage, coating projects must evaluate the actual performance advantages of each coating material.

Surface Coating for Electronics Applications

The following are some cases of coatings:

Acrylic Resin (AR) Coating

The coating has anti-fungal properties as well as electrical and physical properties. It's typically applied at a thickness of 0.002 to 0.005 inches. Coatings can tolerate temperatures of up to 125°C, although many high-temperature applications are out of reach. However, because many AR coatings cure in under 30 minutes, they remain a popular coating option.

Urethane Resin (UR) Coating

The coating offers good chemical and humidity resistance, as well as good long-term dielectric qualities, allowing signal traces to be better isolated from surrounding circuits. PCB shrinking may be aided by this characteristic.

Parylen Coating

To generate a very uniform, pinhole-free conformal film for the PCB, the coating employs a novel CVD application procedure. Its chemical inertness makes it ideal for use in biomedical implants. Parylene is a costly and difficult-to-rework material. The batch size is less than that of other conformal coatings.
