OEM Overview:

About Us

We are a service-oriented company specializing in PCB fabrication and PCBA delivery. Our core team has over 20 years of industry experience, with in-depth knowledge of manufacturing processes for multi-layer PCBs, HDI boards, rigid-flex boards, high-frequency and high-speed boards.

We do not provide PCB design services. Our expertise lies in efficiently and reliably transforming customer-provided design files (Gerber, BOM, pick-and-place files, etc.) into manufacturable, high-quality products.

Our Services

OEM Manufacturing

With complete design files provided by customers, we manage the entire PCB fabrication and PCBA process:

DFM Review: Engineering validation of Gerber files before production—checking trace width and spacing, hole sizes, stack-up structure, impedance control, and other critical parameters to identify and resolve manufacturing risks early.

Production Resource Matching: Optimal production line allocation based on layer count, material type (FR4, high-frequency materials, metal-core, etc.), surface finish requirements (ENIG, OSP, HASL, etc.), and delivery schedule.

End-to-End Quality Control: Full-process monitoring from material cutting, lamination, drilling, and plating to solder mask, surface finishing, profiling, and electrical testing. Mandatory inspection hold points at critical stages, with 100% electrical testing on finished boards.

PCBA Assembly: Component sourcing, SMT placement, DIP insertion, AOI inspection, X-Ray inspection, ICT testing, functional testing (per customer requirements), assembly, and packaging.

Supply Chain Integration

Leveraging long-established supply chain partnerships, we offer:

Component Sourcing: BOM kitting services through reliable component channels, reducing customers' administrative costs of fragmented procurement.

Flexible Capacity Coordination: Agile capacity deployment across multiple manufacturing partners based on order volume, process complexity, and delivery urgency to ensure on-time delivery.

Cost Optimization Recommendations: Reference suggestions on material alternatives, panelization optimization, and surface finish selection to reduce costs without altering the original design.

Quality System

All manufacturing partners are certified with:

ISO 9001 Quality Management System
IATF 16949 Automotive Quality Management
ISO 13485 Medical Devices Quality Management
UL Safety Certification

All products are RoHS and REACH compliant.

Each shipment includes a complete inspection report (impedance test, solderability test, cross-section analysis, etc.) with full traceability.

Production Line:

Bicheng Electronics Technology Co., Ltd

Bicheng Electronics operates two major production bases, strategically located in Shenzhen and Jiangmen.

The Shenzhen factory employs over 300 staff and has a monthly output exceeding 10,000 square meters of PCBs. As a brand-new facility, it specializes in quick-turn prototypes and small-volume production.

The Jiangmen factory features two new industrial buildings spanning approximately 15,000 square meters, specifically designed for mass production. Equipped with state-of-the-art automated machinery sourced from Israel, Japan, Germany, and Taiwan, the Jiangmen facility produces up to 30,000 square meters per month for 2- to 10-layer PCBs. The establishment of this plant has significantly strengthened Bicheng’s capacity to supply high-end PCBs to both domestic and global markets.

With a strong and diverse product portfolio, Bicheng serves customers worldwide. Our offerings include multi-layer boards (up to 32 layers), flex-rigid combinations, heavy copper PCBs, high-frequency and high-speed boards, and HDI, among other types.

We are committed to becoming a leading diversified PCB supplier known for precision-engineered products. Our mission is to create lasting value for our customers while building a promising future for our employees.

History:

BichengPCB is the brand of Shenzhen Bicheng Electronics Technology Co., Ltd. Its origins date back to 2003, when it was known as Bicheng Enterprise Company, specializing in blank printed circuit boards for single-sided and double-sided PCBs.

To meet growing market demand, the company began offering multilayer PCBs in 2008, with layer counts reaching up to 32 layers. In 2010, Bicheng introduced high-frequency materials for applications involving antennas, amplifiers, and radio products.

As the company evolved, metal-core PCBs and hybrid PCBs were successfully trialed and received high praise. In 2014, the company underwent restructuring and reform, with Bicheng taking on a new role within the organization—focusing on global market sales and after-sales services.

By 2020, Bicheng had completed a full range of integrated PCB products, including high-frequency/microwave PCBs, multi-layer/hybrid PCBs, metal-core PCBs, and flexible circuits.

Today, Bicheng’s products can be found in over 100 countries and regions around the world.
