To address the challenging requirement of prototyping complex multilayer PCBs, we offer industry-leading Quick-Turn PCB Prototyping services. Our core capabilities lie in a triple guarantee of speed, precision, and reliability:
For standard double-sided boards, we support 24-hour express delivery. For complex multilayer boards with 6–32 layers (including HDI, high-speed vias, and arbitrary layer interconnects), the standard fast-track cycle is 2–4 business days, meeting the stringent timeframes for R&D iteration and small-batch verification. This cycle includes a complete DFM (Design for Manufacturability) review, engineering validation, production scheduling, and final inspection.
We do not sacrifice quality for shorter lead times. Instead, we ensure design success on the first attempt through full-chain DFM pre-intervention:
All orders undergo mandatory pre-production DFM simulation manufacturing analysis, automatically identifying over 200 potential failure points based on a 2368-rule IPC/industry-certified DFM rule base, including pad defects, impedance deviations, uneven copper thickness, and blind/buried via alignment risks;
For 16–32 layer high-multilayer boards such as AI server motherboards (e.g., TU933+ high-speed materials, 0.2mm minimum hole diameter, 4.5/2.5mil linewidth and spacing), we employ proprietary technologies such as metallized slot precision control, multiple back-drilling + high-density resin filling, increasing the first-pass yield from design to mass production to over 98%;
The entire process is controlled by seven major international quality systems, including ISO9001, IATF16949, and ISO13485, and supported by a CNAS/CMA accredited laboratory, ensuring that every prototype board possesses mass-production-grade reliability.
Technical Note: "Guaranteed manufacturability" does not merely refer to the physical ability to manufacture the board, but rather to avoiding all structural risks affecting signal integrity (SI), power integrity (PI), thermal management, and long-term reliability from the design stage. For example, for AI computing server motherboards, we achieve 25μm fine circuitry using MSAP (modified semi-additive process) technology, coupled with ≥7mil inner layer pad-to-trace spacing control, fundamentally eliminating the risks of high-speed signal crosstalk and thermal stress cracking.
We have built a high-end PCB process platform for cutting-edge hardware R&D, fully adaptable to the complex multilayer board requirements of fields such as 5G communication, AI servers, millimeter-wave radar, and medical imaging:
| Process Dimensions | Technical Specifications | Application Examples |
|---|---|---|
| Number of Layers and Structure | Supports 6–56 layers; HDI up to 10-level staggered vias/4-level stacked vias; Total/Flexible Layers of Rigid-Flex Boards: 30/26 | AI Accelerator Card Stacked HDI Board, 56-layer 112Gbps Backplane |
| Materials and Thickness | High-speed materials (TU933+, RO4350B, Megtron series); Board thickness 4.0–6.5mm; Ultra-thick copper ≥12OZ | High-speed, high-multilayer backplane, high-current power board |
| Microfabrication Capabilities | Minimum aperture 0.2mm; Line width/spacing as low as 2.0/2.0mil (FR4) or 25/25μm (carrier board); Impedance tolerance ±5% | Millimeter-wave radar antenna boards, WB-BGA packaging substrates |
| Special Processes | Stepped gold fingers (adhesive overflow ≤0.2mm), high aspect ratio (≤25:1), immersion gold + gold finger composite surface treatment | Communication equipment connectors, industrial control interface boards |
All process parameters are verified to IPC-A-600G Class 2/3 standards, and support customized DFM rule import to ensure zero deviation between technical specifications and design intent.
Unlike the traditional industry practice of "quick turnaround with cost-cutting," our Quick-Turn approach is speed upgrades driven by deep technological expertise:
Vertical Integration Advantages: Leveraging three manufacturing bases in Shenzhen, Daya Bay, and Xi'an, and five design centers, we achieve a closed-loop process from "Design → Simulation → DFM → Production → Testing," eliminating cross-stage communication losses and compressing mass production cycles to 60% the industry average;
One-Stop IPDM Empowerment: Providing an Integrated Product Design & Manufacturing (IPDM) model, we not only deliver PCBs but also simultaneously provide BOM localization alternatives, thermal simulation reports, EMC pre-compliance recommendations, and mass production process packages, helping customers accelerate product launches by 2x;
Zero-Risk Delivery Commitment: If DFM fails or delivery is delayed due to insufficient process capabilities on our part, we offer free rework + time compensation, truly practicing "customer R&D success as the sole KPI."
Start your Quick-Turn project now! Please provide your Gerber files and technical requirements (number of layers, materials, key characteristics), and we will provide a DFM report and a precise delivery date commitment within 2 hours. Prototyping of complex multilayer boards—no more compromises between speed and reliability.
