Technical Specifications & Capabilities

Superior Protection: Conformal Coating & Potting

To safeguard sensitive electronics against moisture, salt spray, and chemical exposure, we provide automated selective conformal coating compliant with IPC-CC-830 and MIL-I-46058C standards. Our process achieves precise thicknesses (0.025mm - 0.125mm), validated by UV fluorescence inspection. For components requiring total encapsulation, our automated potting services utilize vacuum degassing and UL 94 V-0 rated compounds to ensure high dielectric strength and superior mechanical shock resistance.

Precision Logic: IC Programming & Serialization

Our embedded systems support includes comprehensive IC programming via SWD, JTAG, I2C, SPI, and ICSP protocols. We offer flexible workflows, including pre-assembly flashing or PCBA-level programming, integrated with 100% verification and custom serialization. This end-to-end traceabilty ensures that every device is loaded with the correct firmware version and unique identifier before leaving our facility.

Advanced Quality Assurance: IPC Class 2 & 3

At OminiPCBA, quality is verified through a multi-layered inspection suite. We adhere to IPC-A-610 Class 3 standards for mission-critical applications, utilizing 3D AOI (Automated Optical Inspection) and 3D X-Ray (AXI) to detect hidden solder defects in BGAs and QFNs. This rigorous inspection framework guarantees that your industrial electronics and automotive PCBA projects meet the highest global benchmarks for durability and long-term reliability.

Industry-Specific Applications

For mission-critical electronics, standard manufacturing isn't enough—resilience is a requirement. At Omini PCBA, we specialize in environmental ruggedization designed to protect your hardware against the most unforgiving conditions.

Our high-reliability conformal coating and potting services provide a robust barrier against moisture, salt spray, chemical contaminants, and extreme thermal cycling. By leveraging advanced protective compounds and precision application techniques, we ensure the long-term signal integrity and durability of PCBA for automotive, aerospace, and industrial IoT applications.

To guarantee zero-defect delivery, our specialized processes are anchored by rigorous, multi-stage inspection—including 3D AOI and X-ray validation—to ensure every trace and component remains flawless in harsh environments. Whether your project involves EV battery management systems or marine-grade sensors, we deliver the precision-engineered protection required for mission-critical performance.

Frequently Asked Questions

1.Why should I use Conformal Coating instead of Potting?

Conformal coating is ideal when weight and serviceability are important, providing protection against moisture and dust. Potting is superior for extreme vibration, shock, and total environmental exclusion (hermetic sealing).

2.Can Omini PCBA handle high-volume IC programming?

Yes. Our facility features high-speed automated gang programmers and off-line programming stations capable of processing thousands of units per day with 100% verification.

3.What standards do your special processes meet?

We strictly adhere to IPC-A-610 (Acceptability of Electronics), IPC-CC-830 (Conformal Coating), and MIL-I-46058C military standards where applicable.

4.Do you offer selective coating to keep connectors clean?

Absolutely. Our automated selective coating systems allow us to apply protection precisely where needed while keeping keep-out zones like connectors and switches completely clean without masking.
