High-frequency High-speed PCB Manufacturer for 5G Base Stations

With the popularity of 5G technology, High-frequency High-speed PCBs has progressively become the core \\"nerve center\\" of 5G base station. But with signal loss, ultra-precision impedance tuning, and an unparalleled test of environmental and environmental tolerance in millimeter-wave bands above 28GHz, it is tackling material, manufacturing process and quality management points like never before. A specialized manufacturer 深耕 (deeply rooted) in the communication electronics field, we offer global end-to-end solutions for 5G base station construction through technological innovation and capacity deployment. ​
I. High-frequency High-speed PCBs: The Silicon Foundation of 5G Base Stations
The three pledges of 5G base stations (high speed (10Gbps+), low latency (less than 1ms) and massive connectivity (millions of devices/km²)) come from the signal integrity, which is the main premise for the high frequency high-speed PCB. There are two axes of technical challenges here:​
1. Blurring the Lines Between Sexiness And Safety
Ultra-Low Loss SubstratesPTFE (Polytetrafluoroethylene) composite materials (dielectric constant Dk=2.1·60±0.05, dissipation factor Df<0.0005), signal attenuation reduced over that of 40% in conventional FR-4 (Dk=4.2, Df=0.02), <0.5dB loss per inch 28GHz ​
High-Temperature Stability & Reliability: In Huawei\\\'s 5G base station PA modules, the BT resin substrate (temperature resistance to 220℃, CTE=13ppm/℃) ensures that the impedance remains stable within ±3% over a temperature range of -40℃ to 85℃, perfectly solving the thermal expansion/contraction-induced signal distortion. ​
2. Process innovation in the manufacturing process​
Laser Drilling & Blind/Buried Via technology: 16-layer HDI boards utilize 355nm UV laser drilling (100μm hole diameter, ±5μm positioning accuracy) and second-order blind/buried via processes to minimize signal path lengths by 40% while maximizing in-board wiring density by 30%. ​
Standardized ±5% impedance control could be achieved by Ansys HFSS, while we get the accuracy of ±2% at 10GHz (industry standard); thus, conjugate matching of 50Ω/75Ω characteristic impedance is realized to reduce signal reflection and crosstalk. ​
II. Tailored Solutions: End-to-End Partnership From Design → Delivery​
We have established a vertically integrated closed loop on the model of \\\"requirement definition-joint R&D-mass production\\\" as a critical funnel connecting material suppliers and equipment manufacturers:​
1. Technical Alignment Prior To Designing​
Signal integrity simulation: The thickness of dielectric layer (typical 0.127mm) and copper foil roughness (Rz&<1.5μm) are optimized within full 3D simulation using SI9000 on Massive MIMO antenna array boards, insertion loss reduced by 20%. ​
Thermal Management Design: In the design of the AAU (Active Antenna Unit) PCB, a micro-channel cooling structure is embedded, the copper foil is 3oz (80A current capacity), and the temperature rise of the module can be controlled within 15℃ for outdoor long-term high-load operation; ​
2. Intelligent Manufacturing Capabilities
Digital Production Lines: Implement ASM fully automatic placing machines (±5μm precision) and German Manz laser cutters (500mm/s speed) enabling 24-hour rapid prototyping and cut down lead time at small-to-medium batches to 7-10 days. ​
End-to-End Quality Control: AOI inspection (10μm resolution), X-Ray layer shift measurement (±25μm accuracy), and SATA III signal testing (6Gbps speed) together achieves the stable 98.5% yiled which is 3% higher than the industry average. ​
3. Global Delivery Network​
We have 2 manufacturing bases with Shenzhen and Suzhou respectively (500,000㎡/month in total) as well as a warehouse in Southeast Asia, which allows us to implement fast logistics coverage, covering North America within 3-5 days, Europe 5-7 days, and APAC 2-3 days, significantly lowering customer supply chain costs. ​
III. INSIGHTS: Deep Empowerment for Leading OEMs and Emerging Markets​
1. RELEVANT EXPERIENCE & CLIENTS TO DATE​
Huawei 5G Macro Base StationsMass-supplied 20-layer PTFE composite PCBs for Sub-6GHz BBU (Baseband Unit), supports signal synchronization for 256TR massive antenna arrays (Another Global First)Enabling Huawei to deploy over 1.5 million 5G base stations globally. ​
Design Solution: Customized 12-layer HDI boards based on embedded capacitor technology (±5% capacitance accuracy), suppressing high-frequency noise and enabling stable transmission in 200MHz channel bandwidth for mmWave micro base stations by Nokia mmWave Equipment ​
2. Emerging Market Expansion​
For these accelerating 5G construction regions such as India and Middle East, we provide low cost solutions: (1) asynchronous modified PPO materials (Dk=3.0, 40% lower cost than PTFE) meet Sub-6GHz performance requirement thus allowing local operators to control the single-station PCB within $2000; (2) using low cost Dk=3.0 substrate to decompose the PCB of GRX and RE based on our simulation results, it reduce the cost of single-station PCB within $2000. ​
IV. Raising Confidence and Acceptance of Technology for 6G​
With 6G R&D in the pre-commercial stage (frequency target 100GHz+), we are developing forward-looking technologies:​
Material R&D: Working with Dow Chem for aerogel substrates (Dk=1.8), samples to be evaluated in 2025;​
Process Improvements: $16 million for a 12μm line/space high-order HDI production line; Supports integration of 3D packaging substrate;​
Green Manufacturing: Our electroplating is 100% lead-free (Sn-Ag-Cu alloy), complete with low VOC water-based solder masks (90% lower VOC emissions), pass muster under the EU RoHS 3.0 & China continuous inspection of electronic products, EIPCCM. ​
