Unigen Corporation is pleased to offer cutting-edge in-house conformal coating as a value-add service for customers who require additional protection and reliability for ruggedized environments.
Unigen utilizes a Conformal Coating based upon HumiSeal UV40 which is then UV Cured to save process time and additional heating. The process starts with the company’s in-house 3D printers creating custom masks and caps for the board components that provide exceptional accuracy. A 4-axis 35-degree angled Spray Head is then used to deliver a uniform and complete coating on all surfaces for a truly finished look. This protects electronic circuits from harsh environments, such as high humidity and extreme temperatures.
Unigen’s conformal coating process is electrically insulating, and therefore maintains long-term Surface Insulation Resistance (SIR) levels, providing a barrier to airborne contaminants from the operating environment, such as salt spray, moisture, chemicals and fungus – thus preventing corrosion and extending life of the assembly.
Although Unigen supports many types of HumiSeal applications, the most common material choice is UV40. The single-component HumiSeal UV40 conformal coating has excellent chemical resistance, surface hardness, flexibility and moisture resistance. Additionally, Unigen provides a secondary moisture cure mechanism for curing in the non-UV exposed shadowed areas. To aid coating inspection, the UV40 cure fluoresces under UV light. HumiSeal UV40 is recognized under UL File Number E105698, is MIL-I-46058C qualified, and has the following certifications: IPC-CC-830 certification, RoHS directive 2015/863/EU, China Standard GB30981-2020, ISO 10993-5.
Conformal coating is just one of the many value-added services offered by Unigen in its fully integrated production line, with a factory footprint of over 320,000 square feet with 24 SMT lines across two sites in Hanoi, Vietnam and Newark, California, USA. From NPI to full turnkey, Unigen is your trusted manufacturing partner throughout the entire product life cycle.
