What Is PCB Contract Manufacturing?

PCB contract manufacturing is a process where companies outsource the production of printed circuit boards to a third-party manufacturer. This includes not just making the board, but also assembling components, running functional tests, and sometimes even final product packaging. It allows companies to focus on core tasks like product development and marketing, while the technical side of electronics production is handled by experts.

At its core, PCB contract manufacturing saves time, reduces production costs, and ensures consistency in quality. For startups and global electronics brands alike, finding a dependable contract manufacturer can significantly boost speed-to-market and reduce project risks.

Our Printed Circuit Board Services

At Best Technology, we offer a complete range of services under one roof. Whether you’re developing a new electronic product or scaling up production, we handle everything from the initial design to final functional testing. Here’s what we bring to the table:

PCB Layout & Design

We help you start from scratch or improve your existing Gerber files. Our layout team is experienced in high-density routing, impedance control, and EMC-compliant designs. With tools like Altium Designer and CAD, we ensure accurate and efficient PCB layouts tailored to your project needs.

OEM & ODM PCB Manufacturing

Whether you need OEM or ODM service, we have the capability to take your concept and turn it into a working product. Our engineering team collaborates closely with clients to deliver custom solutions that are production-ready.

Electronic Components Assembly

From SMT (Surface Mount Technology) to through-hole assembly, our facility is equipped for full-scale PCBA (Printed Circuit Board Assembly). We support both leaded and RoHS-compliant assembly and offer automated inspection (AOI), X-ray, and BGA rework services to guarantee every joint is solid and reliable.

Wire Harness Assembly

We also supply PVC/PE/TPU/LZSH hook-up wire, flat cable, connector wire harness for machinery equipment, and cables for the field of electronic appliances, DC power supply, audio video devices, toys, medical equipment, communication devices, electrician & electrical, computer accessories cable, and so on.

Box Building Assembly

We don’t stop at the board level. If you need enclosure integration, cable harnessing, or full unit assembly, our box building assembly service is available. This end-to-end solution simplifies your supply chain and gives you more control over the finished product.

Functional Testing

We provide full functional testing based on your test procedure or help you develop one. This includes power-on tests, signal integrity verification, and custom fixture testing. We ensure your board works perfectly before it reaches your customers.

What PCBs We Can Fabricate?

Our team at Best Technology specializes in a wide range of printed circuit board types. No matter your project’s complexity or environment, we’ve got you covered. Here are some products that we can make, but not limited to these PCBs.

Extra Thin PCB

For devices that require tight packaging like smart cards, cameras, or medical sensors, we offer ultra-thin PCBs as thin as 0.1mm. These boards maintain strength while saving space.

HDI PCB

High-Density Interconnect (HDI) PCBs support advanced electronics with fine-pitch components, blind and buried vias, and micro-via-in-pad technology. These are perfect for smartphones, tablets, and compact IoT devices.

RF PCB

We manufacture RF (Radio Frequency) PCBs using low-loss materials like Rogers, Taconic, and PTFE laminates. These boards are designed for wireless communication, antennas, and radar systems, where signal clarity matters most.

Heavy Copper PCB & Busbar PCB

When high current is involved, such as in automotive or industrial power supplies, heavy copper and busbar PCBs are necessary. We can produce boards with copper thickness from 2oz to 20oz, ensuring excellent thermal and electrical performance.

Metal Core PCB

For LED lighting and power conversion applications, our metal core PCBs (MCPCBs) provide efficient thermal dissipation. Aluminum and copper cores are both available depending on your thermal and mechanical needs.

Ceramic PCB

Using materials like aluminum nitride and alumina, ceramic PCBs deliver outstanding heat resistance and insulation. We have mature manufacturing technologies, including: Thick film ceramic PCB, thin film ceramic PCB, AMB ceramic PCB, DBC & DPC ceramic PCB, HTCC & LTCC ceramic PCB.

Flex Circuit & Rigid-Flex PCB

Flex circuits offer excellent bendability, reducing connectors and saving space. Rigid-flex PCBs combine the best of both worlds and are widely used in wearables, drones, and other portable electronics.

High-Speed PCB

We design and produce high-speed PCBs with controlled impedance, low-loss materials, and proper stack-ups. These are ideal for applications like 5G networks, servers, and high-frequency digital communication.

High TG PCB

When operating temperatures exceed 170°C, High-TG (glass transition temperature) PCBs are the right choice. These boards are more stable thermally and mechanically, perfect for automotive and industrial applications.

IC Substrate

We also support packaging solutions with IC substrates that act as a bridge between chips and PCBs. Our substrates offer fine-line traceability and are used in semiconductor packaging.

Ceramic Packages

Ceramic packages provide superior hermetic sealing and thermal cycling endurance. These are used to package sensitive ICs in defense, aerospace, and critical medical applications.
