Halogen-Free PCBs Guide
Our company is committed to providing high-quality halogen-free printed circuit boards. Halogen-free PCBs lack halogen elements like bromine and chlorine. They meet strict environmental standards. These PCBs are more eco-friendly. They have great thermal stability and electrical properties. So, they suit many high-performance uses.
Product features:
- Fully compliant with RoHS and REACH environmental standards
- Halogen-free content less than 900ppm
- Excellent flame retardant performance (up to UL 94 V-0 level)
- Suitable for multi-layer board manufacturing (up to 32 layers)

Advantages of Halogen-Free PCBs
Halogen-free materials do not release toxic halides when burned.
Halogen-free PCBs have a higher decomposition temperature, and they can withstand higher temperatures without degradation.
Halogen-free materials are less likely to produce corrosive and toxic gases in the event of a fire, reducing risks to personnel and equipment.
Consumers and companies increasingly prefer environmentally friendly products, driving the demand for halogen-free PCBs.
