For procurement managers and NPI engineers sourcing advanced PCB solutions, finding a reliable China Rogers PCB manufacturer that can also handle demanding long PCB formats presents a unique set of challenges. The market is filled with suppliers who either lack the specialized expertise for high-frequency materials like Rogers or the robust production capabilities for large-format, long PCBs. This often forces teams into costly compromises or complex multi-supplier strategies. This guide details the critical pitfalls in sourcing these specialized boards and explains how partnering with a vertically integrated, certified manufacturer like Jerico—combining deep Rogers material expertise with precision long PCB manufacturing—ensures performance, reliability, and cost-effectiveness from prototype to wholesale volume.
The Dual Sourcing Challenge: High-Frequency PCBs and Long PCBs
Sourcing PCBs for advanced applications like 5G infrastructure, automotive radar, or industrial automation panels often involves navigating two distinct but equally complex supply chain challenges. The convergence of high-performance material requirements with large physical dimensions creates a niche that few manufacturers can adequately fill.
The Rogers PCB Expertise Gap
Many PCB factories in China are optimized for high-volume, standard FR4 production. Processing advanced high-frequency laminates like Rogers RO4000® or RO3000® series requires fundamentally different protocols and equipment.
Common failures from inexperienced suppliers include:
- Poor Drilling Quality: PTFE-based materials like Rogers RT/duroid® are soft and abrasive. Standard drill bits and parameters cause excessive smear and rough hole walls, leading to poor plating adhesion and eventual via failure.
- Delamination & Dimensional Instability: The low coefficient of thermal expansion (CTE) of Rogers materials must be matched with appropriate prepregs and pressing cycles. Incorrect lamination leads to layer separation or warpage, especially problematic in hybrid stackups.
- Inconsistent Impedance Control: Achieving ±5% impedance tolerance on Rogers materials demands exceptional control over dielectric thickness and etching. Without dedicated high-precision processes, impedance can vary by ±15% or more, rendering RF circuits ineffective.
The Long PCB Manufacturing Hurdle
Long PCBs (e.g., over 18 inches in length) for applications like LED displays, industrial control backplanes, or automated test equipment introduce another layer of manufacturing complexity that challenges standard production lines.
Critical pain points include:
- Warp and Twist Control: Larger panel sizes are exponentially more susceptible to bow and twist due to uneven thermal stress during lamination and uneven copper distribution. This leads to assembly issues and field failures.
- Etching and Plating Uniformity: Maintaining consistent trace width and copper thickness across a 2-foot or longer panel is extremely difficult. Variances lead to uneven current distribution in power circuits and impedance fluctuations in signal lines.
- Handling and Logistics: Many factories lack the material handling systems, large-format exposure units, and plating tanks required for long PCB production, limiting their capability and driving up cost.
Jerico’s Technical Solution: Dual-Competency Manufacturing
Addressing these challenges requires not just separate capabilities, but their integration. Jerico has built dedicated production lines and process controls that specifically address the intersection of high-frequency performance and large-format reliability.
Precision Rogers PCB Manufacturing Authority
Our expertise with Rogers materials is rooted in specialized equipment and certified processes designed for high-frequency substrates.
- Material-Specific Processing Lines: We operate separate drilling, desmear, and plating lines configured for PTFE and ceramic-filled hydrocarbon materials. This includes using specialized drill bits with optimized feed/speed rates and plasma desmear systems essential for preparing Rogers material hole walls for perfect copper adhesion.
- Advanced Process Control for Impedance: Utilizing laser-based thickness measurement systems and controlled impedance testing (e.g., TDR testing), we actively monitor and adjust processes to maintain dielectric thickness tolerances within ±4% and achieve impedance control of ±5% or better, as required for IPC Class 3 and automotive applications.
- Hybrid Stackup Mastery: A key value we provide is designing and reliably manufacturing cost-optimized stackups that strategically place Rogers material only in critical RF layers, while using cost-effective FR4 for power and digital layers. Our IATF 16949 certified lamination process ensures perfect bonding between these dissimilar materials.
Case Example: 5G Antenna Board
A customer required a 20-layer board for a 5G massive MIMO antenna unit. The initial quotes from other suppliers for an all-Rogers design were prohibitive. Jerico’s Solution: We engineered an 8-layer hybrid stackup where only the two critical antenna feed layers used Rogers RO4350B™, while the remaining layers used a high-performance FR4. This reduced the board cost by over 35% while meeting all RF performance specifications (insertion loss, return loss, and phase consistency). Our TDR report confirmed ±4.8% impedance control across all critical lines.
Engineered Long PCB Production Capability
For long PCB formats, our focus shifts to mechanical stability and process uniformity across large dimensions.
- Specialized Large-Format Presses: We utilize multi-opening hydraulic presses with computer-controlled, multi-zone heating. This allows for a perfectly even temperature and pressure distribution across the entire panel during lamination, minimizing the inherent stress that causes warp and twist.
- Precision Etching for Uniformity: Our vertical conveyorized etching lines are calibrated to ensure consistent etch rates across the entire length of a long panel. This is critical for maintaining precise trace widths and copper weight (especially for heavy copper PCBs used in power distribution), where even minor variations can lead to hot spots.
- Wholesale-Scale Capacity: With a monthly production capacity of 60,000 square meters, our facility is built for volume. We can seamlessly scale from a single prototype long PCB to wholesale batch production, maintaining consistent quality through statistical process control (SPC).

Frequently Asked Questions for Buyers
Beyond basic certifications, ask for specific evidence:
- Request a TDR Report Sample: Ask for an actual Time Domain Reflectometry report from a previous Rogers PCB project. This proves their ability to control impedance, not just claim it.
- Ask for Hybrid Stackup Examples: A manufacturer with real experience will have case studies or samples of boards combining Rogers and FR4 materials.
- Inquire About Material Handling: Do they have separate production lines or dedicated processes for high-frequency materials? How is material stored to prevent moisture absorption?
- Check IATF 16949 Certification Scope: Ensure the certification explicitly covers the production of high-frequency or RF circuits, not just generic PCB assembly.
For long PCBs, dimensional and mechanical stability specs are as critical as electrical ones:
- Bow and Twist Tolerance: Specify this according to IPC-6012 standards (e.g., Class 2: 1.5%, Class 3: 0.75%). For panels over 18 inches, working with a manufacturer like Jerico that has specialized presses is essential to meet these tolerances at volume.
- Copper Thickness Uniformity: Request a tolerance for copper weight variation across the panel length (e.g., 1 oz copper ±10%). This is vital for power integrity.
- Panelization and Routing Method: Discuss how the long boards will be panelized for production and depanelized. V-scoring vs. tab routing can significantly impact edge quality and stress on long, thin boards.
- Material Tg and CTE: For long boards subject to thermal cycles, specify a high Tg material and consider the CTE match to components to prevent solder joint stress.
