Understanding Halogen Free Materials for PCBs
In-house laminate storage at Highleap Electronic
What are Halogen Free Materials?
Halogen-free materials are PCB laminates that contain less than 900 ppm of chlorine or bromine, and under 1,500 ppm total halogens, as defined by IEC 61249-2-21. These eco-friendly materials help reduce toxic emissions and support compliance with global environmental standards.
What Can Highleap Electronic Offer?
We maintain a strong inventory of certified halogen-free laminates, sourced from trusted suppliers and strictly inspected in-house. Our material control ensures every PCB starts with compliant, high-performance substrates—ideal for applications with high environmental or safety requirements.
Common Types of Halogen Free PCB Materials
Modified FR-4
High-Tg Epoxy Systems
High-Tg epoxy systems are halogen-free materials with elevated glass transition temperatures, suitable for multilayer PCBs in automotive and industrial control systems.
BT Resin Systems
Polyimide Materials
Polyimide materials are heat-resistant polymers offering exceptional thermal endurance and flexibility, widely applied in aerospace, automotive, and flexible PCBs.
Cyanate Ester Resins
High Speed Halogen Free Materials
High-speed halogen-free materials are advanced laminates engineered for excellent signal integrity at high frequencies, commonly used in telecommunications and networking equipment.

Why Choose Highleap Electronics for Halogen-Free PCBs?
Material Options
We support PCB projects with customer-specified halogen-free laminate requirements, including materials from established PCB material manufacturers. Material models and availability are confirmed according to each project before production.
Compliance Requirements
PCB materials and production requirements can be reviewed according to customer-specified RoHS, REACH, halogen-free, flammability, and other applicable requirements. Final compliance is confirmed based on the selected material, PCB specification, and required documentation.
Advanced PCB Manufacturing
Our PCB manufacturing capabilities support multilayer boards, HDI structures, laser-drilled vias, controlled impedance, and other demanding rigid PCB constructions, from prototypes to volume production.
PCB Prototyping & Production
Highleap Electronics provides quick-turn PCB prototyping and stable volume production for halogen-free PCB projects. Manufacturing schedules are planned around the approved PCB design, material requirements, fabrication process, and order quantity.
PCB Cost Optimization
We review PCB stack-up, panel utilization, copper construction, board thickness, and manufacturing complexity to identify practical cost-saving opportunities. If an alternative laminate is considered, it is reviewed as a customer-approved material option before PCB production.
PCB Engineering Support
Our engineering team supports DFM review, PCB stack-up planning, impedance requirements, drilling, surface finish, and assembly considerations. Highleap Electronics manufactures and assembles PCBs based on customer-specified materials and does not manufacture PCB laminate materials.
Halogen-Free PCB Manufacturing & Assembly
For PCB projects with customer-specified halogen-free material requirements, Highleap Electronics manages the complete PCB fabrication and assembly process according to the approved design, stack-up, material callout, and production documentation. The laminate itself is a third-party PCB material; our role is to manufacture and assemble the finished PCB.
PCB Fabrication with Specified Halogen-Free Materials
Before production, we review the specified laminate model together with board thickness, copper construction, layer count, drilling requirements, surface finish, and other fabrication details. The approved material designation is then carried through the PCB production process, including multilayer lamination, imaging, plating, solder mask, profiling, inspection, and electrical testing.
PCBA Coordination & Production Traceability
For projects requiring assembly, bare-board fabrication and PCBA requirements are coordinated as one production package. Panel format, component areas, soldering requirements, BOM data, and testing needs are reviewed before SMT or THT assembly. Material identification and production records can also be maintained according to the agreed order requirements for project traceability.
If your project requires a specific halogen-free PCB laminate, send us your Gerber files, stack-up, material callout, BOM, and assembly documents for manufacturing review.
