Our custom wire harness products are widely used in industrial equipment, control boards, consumer electronics, automotive systems and medical devices. Whether you need an OEM wire harness or a complex custom wiring solution, Yihetai ensures reliable quality, fast delivery and competitive pricing.

What Is PCB Wire Harness?

PCB wire harness is a customized cable assembly used to connect printed circuit boards (PCBs) with reliable electrical links for power and signals. It bundles wires, terminals, and PCB-specific connectors into a compact, organized form to fit tight equipment spaces and simplify installation.

Compared with standard cables, custom PCB wire harness solutions are tailored to fit specific PCB layouts, connector interfaces and application environments. They are essential in modern electronic devices where compact design, reliability and precise connectivity are required.

Common Custom PCB Wire Harness Types We Manufacture

At Yihetai, we can manufacture different kinds of PCB Wire Harness for your projects, including:

Wire-to-board harnesses for direct PCB pin connections
Multi-layer PCB signal harnesses with shielding
Power supply PCB wire harness for high-current applications
Waterproof PCB cable assemblies for harsh environments
Flat ribbon-style PCB wire harness for data buses
Overmolded PCB wiring solutions for vibration resistance
Automotive-grade OEM wire harness for PCB power distribution.

Frequently Asked Questions

What is the difference between a PCB wire harness and a standard cable?

A PCB wire harness is designed specifically for board connection and internal equipment routing. It is customized based on connector pitch, wire length, circuit layout, and installation space, while a standard cable is usually built to general specifications.

Can you produce PCB wire harnesses based on our drawings or samples?

Yes. Yihetai can manufacture based on customer drawings, samples, BOM lists, and application requirements. This is consistent with the custom manufacturing model described in your company materials.

What connector brands can you work with?

We can work with common connector systems such as JST, Molex, TE, Hirose, Dupont, IDC, wafer housings, and equivalent custom connectors, depending on your design and sourcing requirements.

Do you support low-volume prototype orders?

Yes. Yihetai supports prototype development, small batch production, and mass production for custom wire harness and cable assembly projects.

How do you ensure the quality of each PCB wire harness?

We follow a controlled manufacturing and inspection process that includes incoming material inspection, crimp inspection, assembly verification and 100% electrical testing. Depending on the project, we can also perform insulation resistance, hi-pot and pull force tests to ensure the harness meets the required performance standard.
