SHENZHEN, China, November 10, 2026

The race to build AI hardware is no longer only about chips. Every new generation of AI servers, accelerator boards, and edge devices needs denser printed circuit boards, cleaner power and signal delivery, and wiring that can hold up under heat, vibration, and constant use. That shift is pushing demand for high-reliability PCBs, PCB assembly (PCBA), and custom wire harnesses to new levels this year and five specialist brands operated by the same China-based group say they are built for exactly that work.

The five brands are WellPCB and OurPCB, which deliver PCB and PCBA fabrication services; Wiringo and Xdpigo, which specialize in custom wire harness manufacturing; and Cloomtech, which provides precision assembly support. Together, they serve global customers in AI hardware, automotive, medical, and industrial electronics.

Why AI hardware is changing what buyers ask from a factory

A standard server board and an AI accelerator board are very different jobs. AI boards pack thousands of connections into a small footprint, move data at much higher speeds, and draw far more power. In practice, that means more layers, high-density interconnect (HDI) structures, controlled impedance, and materials chosen for signal integrity not just for cost.

The market numbers point in the same direction. Prismark reported that the global PCB market reached about USD 85.8 billion in 2025, up 16.7% year on year, with much of the growth coming from AI infrastructure, high-speed networking, and advanced substrates. TrendForce has also raised its 2026 AI server shipment growth forecast to close to 31%, driven by heavy capital spending from cloud service providers. Each of those servers carries more board value and more wiring than the machines it replaces.

For hardware teams, the problem is practical. Capacity for complex boards is tightening, lead times for standard and high-end boards are starting to separate, and a late or failed board can hold up an entire product launch. Buyers are therefore looking earlier for manufacturing partners who can move from prototype to production without handing the project from one supplier to the next.

"The explosive growth of AI hardware has brought sustained demand for high-reliability PCBs and wiring assemblies. Our portfolio of brands is well-positioned to support global hardware developers with fast-turn, reliable manufacturing services," said Hommer Zhao.

How the five brands divide the work

PCB and PCBA fabrication - WellPCB and OurPCB

WellPCB provides one-stop PCB manufacturing and assembly, covering rigid, flex, and rigid-flex boards, HDI builds, and multilayer boards up to 64 layers, along with component sourcing, testing, and inspection. It is positioned for teams that want fabrication and assembly handled in one place, from early prototypes through to larger production runs.

OurPCB focuses on PCB prototype fabrication and turnkey PCB assembly. Its service includes design-for-manufacturing (DFM) review before production, component sourcing from authorized distributors, and assembly for both low-volume and high-volume orders. That combination suits developers who are still refining a design and need honest feedback on manufacturability before they commit to scale.

Custom wire harness manufacturing - Wiringo and Xdpigo

A board is only part of a finished system. Power and data still have to get in, out, and around the machine and that is the work of the harness.

Wiringo builds custom wire harnesses and cable assemblies to customer drawings and samples, with engineering support, first-article inspection, and testing that includes continuity, insulation resistance, and high-voltage checks. It serves automotive, industrial, robotics, and medical applications, where a harness must fit exactly and perform the same way on the thousandth unit as on the first.

Xdpigo also specializes in custom wire harness manufacturing, and adds a production option many procurement teams are now asking for: harness and cable production from Cavite in the Philippines, alongside the group's China base. For buyers building a second source or a China+1 supply plan, that gives them one group with more than one production location to choose from.

Precision assembly support - Cloomtech

Cloomtech provides precision assembly support, including custom cable and wire harness assembly, prototyping, global material sourcing, and testing. It works with OEMs that need a reliable production partner who can start with small prototype runs and scale with the program while the customer keeps control of the design and specifications.

One group, one conversation

Because the five brands sit under one group, a customer does not have to manage five separate relationships for one product. A typical program can start with a prototype board, move into turnkey assembly, and add the custom harness that connects the finished unit with the engineering conversation carried across each stage. The group is based in China and serves clients worldwide, supporting projects from first samples to repeat production.

The brands' combined work covers the sectors feeling the AI effect most directly, and several that feel it indirectly: AI hardware and data-center equipment, automotive and electric vehicle electronics, medical devices, industrial automation and controls, and other industrial electronics where reliability is not optional.

Questions hardware teams are asking in 2026

Why do AI servers need more advanced PCBs than standard servers?

AI accelerator boards carry far more connections, faster signals, and higher power loads in the same space. That requires higher layer counts, HDI structures, and controlled impedance so signals stay clean and power stays stable.

What is the difference between PCB fabrication and PCBA?

PCB fabrication makes the bare board. PCBA is the next step mounting and soldering the components onto that board, then testing the finished assembly so it is ready to use in a product.

Why does the wire harness matter in AI and industrial equipment?

The harness carries power and data between boards, power supplies, sensors, and controls. If it is poorly built, even a perfect board will fail in the field. Custom harnesses are built to the exact length, connector, and protection each machine needs.

Can one supplier handle both the board and the harness?

Yes. Through this group, PCB and PCBA work is handled by WellPCB and OurPCB, custom wire harnesses by Wiringo and Xdpigo, and precision assembly support by Cloomtech so the board, the assembly, and the wiring can be coordinated in one program.

About the Group

The group behind WellPCB, OurPCB, Wiringo, Xdpigo, and Cloomtech is based in China and serves customers worldwide. Its brands cover PCB fabrication, PCB assembly, custom wire harness and cable assembly manufacturing, and precision assembly support for the AI hardware, automotive, medical, and industrial electronics industries. Each brand keeps its own specialist focus, while customers benefit from shared manufacturing depth, engineering support, and global delivery.
