Expert Mixed PCB Assembly Services for Industrial OEMs

Seamlessly integrating Surface Mount Technology (SMT) and Through-Hole Technology (THT) for high-reliability electronics. Trusted by global procurement managers for precision and scalability.

Why Choose Mixed PCB Assembly?

In the evolving landscape of industrial electronics, Mixed PCB Assembly remains a critical requirement. While Surface Mount Technology (SMT) offers miniaturization, Through-Hole Technology (THT) provides the necessary mechanical strength for connectors, heavy transformers, and high-power components.

At Omini PCBA, we bridge the gap. Our mixed technology process ensures that your legacy components and modern microcontrollers coexist perfectly on a single board. We support hardware engineers and OEM procurement teams who cannot compromise on durability or performance.

Frequently Asked Questions

1.What is Mixed PCB Assembly?

Mixed PCB assembly involves using both Surface Mount Technology (SMT) and Through-Hole Technology (THT) on the same printed circuit board. This allows manufacturers to utilize small, efficient SMT components while retaining the mechanical strength of THT components for connectors and power supplies.

2.How does Omini PCBA handle quality control for mixed technologies?

We employ a multi-stage inspection process. SMT components are inspected via AOI (Automated Optical Inspection) immediately after reflow. THT components undergo visual inspection and, where necessary, automated selective soldering validation. The final board is subjected to X-Ray (for hidden joints) and functional testing.

3.Can you handle RoHS and Non-RoHS manufacturing?

Yes. Omini PCBA maintains separate process lines to ensure full compliance with RoHS directives for consumer/industrial goods, while also supporting leaded processes for specialized military or medical applications where exemptions apply.

4.What information is needed for a quote?

To provide an accurate quote, we require Gerber files, a Bill of Materials (BOM) indicating which parts are SMT vs. THT, and any specific assembly drawings or testing requirements.
