Manufacturing Rogers material PCBs requires specialized equipment, materials expertise, and process control beyond standard PCB fabrication. At HILPCB, we've produced over 50,000 Rogers boards for wireless, aerospace, and automotive customers. This guide walks through our complete manufacturing workflow—from receiving your design files to shipping finished assemblies.
Understanding this process helps you optimize designs for manufacturability, reduce costs, and accelerate time-to-market for Rogers PCB projects.
Engineering Design Review and File Preparation
Within 4 hours of receiving your Gerber files, our engineering team performs comprehensive design for manufacturability (DFM) analysis.
File Format Acceptance:
- Gerber RS-274X or ODB++ preferred
- Native CAD files: Altium, Eagle, KiCad
- IPC-2581 for complete assembly data
- Use our Gerber viewer to preview before submission
Critical DFM Checks for Rogers Material:
- Impedance Verification: Calculate trace widths for target impedance using actual Rogers material properties. Tolerance: ±7% achievable, ±5% with premium process.
- Minimum Feature Sizes: 4mil/4mil standard, 3mil/3mil for fine-line capability. Rogers materials etch differently than FR4 PCB.
- Via Aspect Ratio: Maximum 12:1 for reliable plating. Rogers PTFE materials require conservative ratios due to drilling characteristics.
- Layer Registration: ±3mil standard, ±2mil for tight-tolerance HDI PCB construction.
Common Design Issues We Fix:
Impedance Tolerance Too Tight: Customer specifies 50Ω ±3%, achievable is ±7%. Solution: Adjust specification or widen traces for better tolerance.
Mixed Copper Weights: 0.5oz and 2oz copper on same layer causes plating problems. Solution: Use uniform copper or split into separate heavy copper PCB layers.
Inadequate Thermal Relief: Rogers materials have different thermal characteristics than FR4. Solution: Add thermal vias, copper pours, or high thermal PCB integration.
Poor Panel Utilization: Single board wastes 70% of material. Solution: Array multiple boards, optimize spacing, reduce cost by 40%.
Our 3D viewer helps visualize stackup construction and identify mechanical interferences before fabrication.

Frequently Asked Questions – Rogers Material PCB Manufacturing
Q1: What's the difference between Rogers PCB and standard FR4 fabrication?
A: Rogers materials require specialized lamination (different temperature/pressure), modified drilling parameters (especially PTFE-based), plasma treatment for plating adhesion, and specific etching chemistry. Our facility has dedicated Rogers processing equipment.
Q2: Can you manufacture mixed Rogers and FR4 stackups?
A: Yes, hybrid stackups are common for cost optimization. Critical considerations: CTE matching between materials, proper prepreg selection, balanced construction to prevent warpage. We provide free stackup design consultation.
Q3: Do you provide impedance calculation services?
A: Yes, free impedance calculations included with every Rogers PCB order. Submit your target impedance and frequency—our engineers calculate trace widths using Rogers material data and provide detailed reports within 24 hours.
Q4: What certifications do you have for Rogers PCB manufacturing?
A: ISO 9001:2015, IATF 16949 (automotive), IPC-A-600 Class 2/3, UL listing. Rogers materials are RoHS compliant. We provide complete material traceability for aerospace and medical applications.
Q5: How do you ensure consistent impedance across production batches?
A: We test 100% of boards using TDR measurement on dedicated test coupons. Material certificates verify dielectric constant. Process control monitors trace width, copper thickness, and substrate thickness. Statistical process control (SPC) tracks impedance trends across batches.
