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
