Description
Eco-Friendly & High-Reliability Halogen-Free PCBs
As environmental regulations tighten globally, Halogen-Free PCBs have transitioned from an optional “green choice” to an industry standard for premium electronics. At FX PCB, we provide high-performance, compliant printed circuit boards that drastically reduce environmental impact without sacrificing electrical or thermal performance.
Technical Specifications & Global Compliance
Our halogen-free PCBs are fully traceable and certified to meet the most stringent international standards:
Strict Halogen Limits: Fully compliant with IEC 61249-2-21 and IPC-4101B. Chlorine (Cl) and Bromine (Br) levels are strictly maintained under 900 ppm each, with total halogens under 1500 ppm.
Superior Thermal Profile: Engineered with high-performance resins featuring high Tg (up to 170℃ and above) and exceptional Td (Decomposition Temperature) for stable, lead-free reflow soldering.
Low Moisture Absorption: lower moisture absorption compared to standard boards, reducing the risk of CAF (Conductive Anode Filament) failures.
How Our Halogen-Free PCBs Are Manufactured
To achieve true halogen-free compliance, every single layer and material in our manufacturing process is carefully selected and audited:
Advanced Substrate Materials: Standard FR-4 relies on brominated flame retardants. For our Halogen-Free boards, we utilize specialized Halogen-Free FR-4 formulations (using phosphorus-nitrogen compounds), as well as Polyimide (PI) and PTFE-based materials for high-frequency or flexible applications.
Precision Conductive Traces: High-purity copper traces are deposited and defined via advanced etching and plating processes, ensuring optimal signal integrity and fine-line capability.
Eco-Friendly Solder Mask: We apply specialized epoxy-based or acrylic-based solder masks that are 100% free of halogenated pigments and compounds, providing reliable insulation and flame retardancy.
Compliant Surface Finishes: To prevent copper oxidation and ensure flawless assembly, we offer a wide range of green surface finishes, including Immersion Silver (IAg), Immersion Tin (ISn), ENIG, and OSP (Organic Solderability Preservatives).
The Strategic Investment: Cost vs. Market Advantage
Why choose Halogen-Free while the cost is higher ?
While advanced green resins carry a slightly higher raw material cost compared to traditional FR-4, upgrading to halogen-free materials protects your product lifecycle:
Seamless Market Entry: Bypass strict customs regulations and environmental audits in the EU, Japan, and North America.
Better Mechanical Reliability: The lower Coefficient of Thermal Expansion (CTE) in halogen-free laminates provides better reliability for complex, multi-layer designs.
