3. Unixplore's VFD PCBA Manufacturing Advantages

Professional Engineering Support

Before manufacturing VFD PCBAs, our 20 R&D engineers will review your design files. We will recommend the most suitable copper thickness and trace width solution based on your current load requirements (referencing the IPC-2152 standard), balancing cost and performance.

High-Precision Production Equipment

We have 6 SMT production lines equipped with Yamaha high-speed placement machines and 10-zone reflow ovens. For high-power components on VFD PCBAs, we ensure the wettability and mechanical strength of the solder joints, reducing void rates.

Rigorous Reliability Testing

Every VFD PCBA undergoes a rigorous testing process, including:

AOI & X-Ray Inspection: Ensuring defect-free soldering of BGA and power devices.

Aging Test: Conducting powered testing in two dedicated aging test chambers, simulating actual working environments.

High and Low Temperature Environmental Testing: Ensuring that the PCBA does not experience performance drift in extreme industrial environments.

5. Frequently Asked Questions (FAQ)

Q: Is 2oz copper thickness sufficient for VFD PCBAs? 

A: This depends on your rated power. For most small to medium power 220V/380V inverters, 2oz copper thickness is the mainstream choice for balancing cost and conductivity. However, for high-power industrial drives, we recommend using 3oz or localized thickening for critical traces. 

Q: How do you handle parts procurement for PCBA? 

A: We have a well-established supply chain system. All core components for the PCBA (such as electrolytic capacitors and power modules) are sourced from authorized distributors, ensuring 100% genuine parts.

Q: Can you perform Functional Testing (FCT)? 

A: Yes. We can perform comprehensive testing of voltage, signal, and logic functions on the assembled VFD PCBA according to the test guidelines or fixtures provided by the customer.
