What is a One-Stop PCBA Solution?

Before officially launching our one-stop PCBA service, we first clarify the core definition of "PCBA"—it is a general term for "PCB manufacturing, component placement, and finished product assembly." The "one-stop" PCBA model refers to end-to-end service ranging from "customer requirement communication" to "finished product delivery and after-sales service," eliminating the hassle of customers coordinating with multiple suppliers. It truly realizes the closed-loop service of "requirement submission → solution implementation → finished product delivery," solving the pain points of customers such as "multi-party communication, cumbersome processes, and fragmented responsibilities."

With "precision manufacturing + flexible PCBA services" as our core advantage, we turn every PCBA into a reliable cornerstone for customers' electronic products.

Our Philosophy

With precision manufacturing as the foundation and customer needs as the guide, we adhere to the standards of "high yield rate, fast delivery, and strong adaptability," provide targeted, reliable SMT/PCBA solutions, empower customers to reduce costs and increase efficiency, and jointly build core product competitiveness.

We focus on the in-depth R&D of SMT placement technology and take high-quality standards as the benchmark. We provide flexible, tailor-made services, making every PCBA a reliable cornerstone in our customers' products.

Regarding customer success as our responsibility, focus on the full-process pain points of SMT/PCBA, and through "precision placement + intelligent management + cost optimization," achieve "fast response for small batches and stable delivery for large batches." We conduct collaborative innovation with customers to jointly drive the efficient development of the industry.

Why Choose Us?

As a key link in computer peripheral manufacturing (e.g., mechanical keyboards), SMT (Surface Mount Technology) is crucial for ensuring the quality and stability of core components such as mechanical keyboard PCBs and keyboard main control boards. We have a professional SMT team focusing on computer peripheral electronic components (e.g., mechanical keyboard circuit chips and keyboard functional modules) and their placement requirements. The team can precisely configure placement parameters and optimize SMT processes according to different product requirements, including mechanical keyboard PCB assembly and keyboard core board processing.

Cleanliness Class: Class 10,000; Constant Temperature: 23±2℃; Humidity: 45±5%. This controlled environment effectively avoids dust interference with SMT component placement, ensuring the precision of PCB assembly in high-demand scenarios.

Production Line Configuration: 3 intelligent SMT production lines (2 high-speed lines + 1 medium-speed line). Each line adopts a complete workflow: "screen printer → SMT placement machine → reflow oven → AOI inspection". High-speed lines support large-batch production of standard products, while medium-speed lines are optimized for small-batch custom PCB processing.

Qualification Certifications (Aligned with Industry Requirements)

ISO9001:2015 (General Manufacturing Quality Management System) – ensures stable quality throughout the entire SMT/PCBA process
IATF16949:2016 (Automotive Electronics-Specific Certification) – meets strict automotive-grade reliability and durability requirements
ISO13485:2016 (Medical Electronics-Specific Certification) – complies with rigorous cleanliness and traceability standards for medical device PCBs
RoHS 2.0/REACH – adheres to EU environmental regulations, restricting the use of hazardous substances in electronic components

We provide end-to-end electronic manufacturing OEM services for computer peripheral customers, covering "PCB design support (e.g., mechanical keyboard PCB layout optimization), component sourcing (including core parts such as Cherry MX switches for mechanical keyboards and sensors for game mice), SMT placement production (for peripheral PCBA boards), finished product inspection, assembly (e.g., mechanical keyboard keycap installation), and packaging with a strong emphasis on Keyboard OEM & ODM capabilities."

PCBA assembly equipment

Our company is equipped with advanced SMT equipment specifically designed for computer peripheral production, including high-speed Yamaha SMT placement machines (e.g., YS12/YS24), precision reflow soldering machines, and AOI inspection equipment. These devices can place small electronic components required for computer peripherals with high speed and precision. Whether for large-scale production or custom manufacturing, we can provide stable and reliable SMT solutions to meet the specific needs of computer peripheral manufacturing.

We offer flexible cooperation models for startup clients

A one-stop computer peripheral OEM/ODM manufacturing service provider, offering full-process PCB design, SMT placement, assembly, and packaging—helping clients reduce mechanical keyboard manufacturing costs by 10%.

We have mature electronic component supplier networks (covering passive components, IC chips, and connectors), ensuring we can secure competitive, high-quality quotes for components in customers' BOM lists. Additionally, we can offer alternative electronic component solutions that meet performance standards to help cut costs and shorten production lead times.

Our SMT lines deliver efficient, accurate SMT placement (Surface Mount Technology) and DIP insertion (Dual In-line Package), monitor production via MES (Manufacturing Execution System), support real-time data collection, analysis & integration, and offer three-proof coating (anti-moisture, anti-corrosion, anti-mildew) for PCBA — all to meet diverse PCBA needs.

We are capable of conducting targeted electrical performance testing, aging testing, and reliability testing for PCBA products strictly in accordance with customer-customized specifications. We also provide professional assistance to customers with respect to a full range of product certifications like CE, FCC, and RoHS.

We can assist customers with laser engraving (for computer peripheral parts like mechanical keyboard casings), structural component assembly (e.g., PCB bracket installation), and finished product assembly. By integrating these multi-link manufacturing support, we streamline their computer peripheral management processes and reduce overall product costs in peripheral production.

MES (Manufacturing Execution System): Real-time monitoring of production data (including SMT yield rate and equipment status) and full traceability of each peripheral PCB production record, ensuring production transparency.

Intelligent Temperature Control System: Customizing reflow soldering profiles according to different solder paste types, resulting in a solder void rate of ≤5% for precision chips (e.g., BGA chips on game keyboard PCBs) to meet the precision requirements of peripheral PCBs.
