R&D and Engineering Capability
JQPCB has a dedicated engineering and R&D team focused on pushing PCB manufacturing boundaries. We work closely with customers from design to mass production, helping turn complex electronic designs into reliable, manufacturable boards.
Our Engineering Strengths
DFM (Design for Manufacturing) support — our engineers review customer Gerber files and provide feedback before production, reducing design risks
Process development — expertise in HDI, fine-line technology, high-frequency (Rogers), rigid-flex and thick-copper processes
High-layer-count capability — up to 60 layers, with strict layer alignment and impedance control
Testing and validation — AOI, flying-probe E-test, impedance test and cross-section analysis on every production batch
Continuous improvement — regular investment in drilling, plating and inspection equipment to improve accuracy and consistency
Working with Our Engineering Team
Our engineers speak fluent technical English and are experienced in customer drawings and international standards. From prototype review to mass production, we stand behind every board we ship.
Send us your Gerber files and specifications, and our engineering team will support your project from day one.

History:
Company History
JQPCB was founded with a simple mission: to be a reliable and professional PCB manufacturing partner for engineers and companies worldwide.
From our early days, we focused on building solid foundations in quality, process control and on-time delivery. What started as a standard PCB fabrication workshop has grown into a specialized manufacturer serving demanding industries.
Our Development Milestones
Early stage — started with standard double-sided and multilayer FR4 PCBs, building a reputation for stable quality
Technology expansion — gradually added HDI, fine-line and controlled impedance capabilities to meet customer demands
High-end specialty — expanded into rigid-flex, high-frequency (Rogers) and IC substrate / probe card PCB manufacturing
Global service — today we serve customers in Europe, North America and Asia, from prototype to mass production
Today, JQPCB combines stable manufacturing capability, strong engineering support and competitive pricing. We continue to invest in equipment and process improvement to support our customers' most challenging projects.
Service:
We are committed to providing one-stop, full‑process electronic manufacturing services covering four core areas: BOM sourcing, CAD design, PCB fabrication, and SMT assembly. In BOM sourcing, we offer professional component selection and supply chain procurement to ensure material quality and on‑time delivery. Our CAD design capabilities handle complex, high‑density, and high‑speed board designs, supporting up to 48 layers, 40,000 pins, and 28 Gbps differential signaling, meeting the most demanding requirements. Our PCB fabrication utilizes advanced precision processing, supporting minimum trace width/spacing of 2 mil, minimum mechanical drilled hole of 6 mil, and laser microvia of 4 mil, to satisfy high‑reliability product needs. Our SMT assembly is equipped with state‑of‑the‑art placement lines, enabling high‑accuracy surface‑mount and assembly. By integrating the entire chain from material procurement and design development to production assembly, we help customers effectively shorten R&D cycles, reduce overall costs, and enhance the market competitiveness of their final products.
