Quora Q&A | What is a Halogen-Free PCB?2025-05-08 23:24:46
A halogen-free PCB is a type of printed circuit board that is manufactured without the use of halogenated flame retardants, specifically compounds containing chlorine (Cl) or bromine (Br). These chemicals are commonly found in standard PCB materials but can release toxic and corrosive gases when burned.
Key Characteristics of Halogen-Free PCBs:
Halogen content <900 ppm (per IEC 61249-2-21 standard for Br and Cl each)Total halogen content <1500 ppm
Use non-halogenated flame retardants, such as phosphorus- or nitrogen-based compounds
Typically made with specialized resin systems (e.g., modified epoxy, BT, or phenolic resins)
Advantages:
Eco-Friendly & RoHS CompliantReduced Toxic Smoke in case of fire
Less Corrosive to Equipment
Often has better thermal and electrical properties
Applications:
Consumer electronics (especially brands aiming for green compliance)Automotive and aerospace electronics
Medical devices
Server and telecom equipment
If you're working on electronics that require environmentally friendly, low-toxicity solutions, a halogen-free PCB is a smart choice.
