Suntronic Provides PCB Conformal Coating Services to Electronics Manufacturers in California

HOUSTON, Texas – Suntronic, a trusted Electronics Manufacturing Services (EMS) provider with more than 27 years of industry experience, today announced the availability of its PCB Conformal Coating Services for electronics manufacturers in California. The service helps OEMs, technology companies and industrial manufacturers outsource specialized PCB coating requirements or integrate conformal coating with PCB assembly through a single manufacturing partner.

Electronic assemblies can be exposed to moisture, humidity, dust, chemicals, temperature fluctuations and vibration, which may affect PCB performance and reliability. Certain California air-quality requirements also address volatile organic compound emissions associated with solvent and surface-coating operations, including printed circuit board manufacturing and assembly.
Suntronic provides flexible outsourcing options for manufacturers seeking PCB protection. Customers can send existing PCB assemblies to Suntronic for conformal coating or choose an integrated solution where Suntronic builds the PCB assembly and applies the required coating. This approach helps manufacturers simplify production, reduce supplier coordination and address specialized coating requirements.

“Manufacturers need flexible solutions when managing specialized PCB protection and production requirements,” said a spokesperson for Suntronic. “Our conformal coating capabilities allow customers to outsource coating for existing PCB assemblies or combine PCB assembly and conformal coating through one manufacturing partner.”

Suntronic offers several conformal coating materials, including silicone, acrylic, parylene, epoxy, polyurethane and thin film/nano coatings. These options provide different characteristics for applications involving moisture, humidity, temperature changes, chemicals and other environmental conditions. Suntronic works with customers to determine an appropriate coating approach based on their PCB design and application requirements.

The company also supports multiple application methods, including manual spraying, automated spraying and dipping. These methods provide flexibility for different PCB designs, production volumes and coating requirements. Manual spraying can support prototype and lower-volume projects, while automated spraying provides a repeatable process for production applications. Dipping can be used for suitable assemblies requiring broader coating coverage.

Suntronic's conformal coating services are available from prototypes through bulk production and can be integrated with its broader PCB assembly capabilities. Engineering support is available to help customers address coating compatibility and application requirements during design and development.

For California electronics manufacturers looking to outsource conformal coating, Suntronic provides both conformal coating and integrated manufacturing solutions. Customers can outsource coating for existing PCBs or have Suntronic build and coat the assembly as part of a broader PCB manufacturing program.

The availability of these services reflects Suntronic's commitment to providing flexible, scalable and integrated electronics manufacturing solutions for OEMs and technology companies.
