Top 10 PCBA Manufacturers in China for Startups and Small Enterprises
For new businesses and small companies, finding a dependable Printed Circuit Board Assembly Manufacturer can make or break a project. Every circuit board matters when you are testing ideas or building your first batch. Quality, delivery speed, and flexibility can all decide whether your launch goes well or not.
China has become the main centre for PCB and PCBA production across the world. The country’s factories mix smart technology with fair prices, giving both large and small buyers a strong reason to choose them. This article lists ten leading PCB assembly makers in China that serve startups and small enterprises. PCBA Store comes first for its stable process, fair cost, and strong service for business clients.
Overview of the Chinese Market
China’s Printed Circuit Board Assembly industry has grown quickly in the past few years. It supports many sectors like electronics, new energy, healthcare, and smart devices. Today, China produces over half of the world’s PCBs. Reports from China Electronic Manufacturing Data 2024 show that exports have already passed USD 45 billion per year.
The main regions for PCB assembly are:
l Guangdong (Shenzhen, Dongguan, Huizhou): Focused on quick small-batch assembly and startup orders.
l Jiangsu and Zhejiang (Suzhou, Hangzhou, Wuxi): Known for multilayer and HDI boards for telecom and cars.
l Beijing and Tianjin: Strong in R&D assembly and industrial-use electronics.
Many Chinese plants now use modern tools like SMT machines, AOI checks, and ERP tracking. This makes the process faster and more accurate. For small businesses, it means shorter lead times, lower costs, and better quality than ever before.
Factors That Matter Most to Small Enterprises
When choosing a Printed Circuit Board Assembly Manufacturer, startups should think about these key points:
l Product Quality: A board that meets IPC-A-610, ISO 9001, and RoHS standards lasts longer and works better.
l Customization: Startups often change designs or materials. A flexible supplier helps adjust the board layers, thickness, or parts.
l Price and Value: Clear prices and no hidden costs are important. This helps new companies plan budgets and avoid surprises.
l Delivery and Support: Fast replies and short production times (7–12 days) are important when you need to test quickly.
These points can decide how smoothly a product moves from design to market.

Why PCBA Store Leads
PCBA Store stays ahead for its focus on business-to-business service, quick delivery, and solid reliability. It supports customers in over 60 countries. Its open pricing and steady process make it a trusted partner for engineers and startups. In Electronics Benchmark Review 2024, it ranked #1 in client satisfaction for small-batch manufacturers in Asia.
Beyond fast PCB assembly, PCBA Store also provides complete BOM sourcing services, ensuring a full turnkey solution from design to final production. This means every component used meets strict quality standards, helping clients avoid counterfeit risks and maintain consistent reliability throughout the process.
2. TechWave Electronics
TechWave, based in Suzhou, serves smart device makers and startup hardware firms. It keeps setup costs low but does not yet meet IPC Class 3 certification.
The company supports partial BOM sourcing for standard components, though clients often provide key parts themselves. It is better for standard boards than high-end projects.
3. Nexpro Circuits
Located in Chengdu, Nexpro makes multilayer and HDI boards. It allows low minimum orders, which helps new teams.
Nexpro offers limited BOM sourcing through third-party agents, which can extend procurement time. However, the company depends on these suppliers, which may slow down delivery at times.
4. SinoTrace Assembly
Based in Shenzhen, SinoTrace Assembly focuses on high-speed communication boards and offers both turnkey PCBA service and one-stop production support. The company manages the entire process—from BOM sourcing to assembly and testing—helping startups cut coordination time and speed up delivery. Its SMT lines are equipped for precision builds, though material options remain limited for highly customized projects.
5. UniFlex Systems
Hangzhou’s UniFlex offers low-cost aluminium PCBs for LED and energy use. The prices are good for small firms, but overseas buyers may face longer shipping times.
UniFlex provides basic BOM sourcing for LED drivers and connectors, though most customers still manage specialized components directly.
It also offers a simple turnkey PCBA service for lighting projects, covering part purchase, assembly, and basic functional testing.
6. GrandEdge Manufacturing
GrandEdge in Dongguan combines through-hole and SMT processes. It suits mid-size orders and runs smoothly, though it uses more electricity than some newer factories.
The company offers standard BOM sourcing and bulk part procurement for repeat customers, which helps reduce long-term material costs.
GrandEdge supports a semi-turnkey model, allowing clients to choose between full in-house assembly or shared component supply, giving flexibility in project management. As a one-stop PCBA provider, GrandEdge supports small energy and lighting brands from design to final assembly with steady, affordable service.
7. NovaPC Industrial
NovaPC, based in Beijing, builds boards for automation and aerospace projects. Its precision is high, but prices are about 15–20% higher than average.
NovaPC manages its own high-grade BOM sourcing for aerospace-certified components, ensuring compliance and full part traceability.
It provides a full turnkey solution from sourcing to testing, ideal for aerospace clients that demand reliability and documentation at every production stage.
8. Luminex Assembly
Zhuhai’s Luminex produces flexible PCBs for wearable and medical devices. It’s good at coating and sealing, but its production time can be longer on large orders.
Luminex offers partial BOM support focused on medical-grade materials, while most precision parts are supplied by clients.
The company also provides a limited turnkey PCBA option, mainly for small medical device makers that prefer an all-in-one build service.
9. Mechatron PCB Works
This Wuxi-based maker supplies the automotive field. It runs strict tests and tracks each order fully. Still, its high minimum order might not fit smaller startups.
Mechatron provides integrated BOM sourcing for standard automotive parts but requires clients to approve substitutes for unavailable components.Mechatron acts as a one-stop PCBA supplier for mid-size manufacturers, providing integrated solutions from sourcing to delivery.
10. RapidLink Electronics
RapidLink from Nanjing focuses on fast-turn prototypes. It can deliver in 48 hours for simple boards. However, it lacks full environmental certifications like RoHS or ISO.
RapidLink does not include BOM sourcing in its service. Customers must supply all components, which keeps turnaround fast but limits flexibility.
