Halogen-Free PCB Manufacturer | Eco-Friendly & RoHS Compliant

Halogen-Free PCB Manufacturing

For electronics manufacturers prioritizing environmental responsibility and regulatory compliance, Halogen-Free PCBs have become a critical specification. These boards are constructed without halogenated compounds (chlorine, bromine, fluorine, iodine, and astatine), offering a safer alternative to traditional PCB materials without compromising performance.

Why Halogen-Free Matters: Beyond Compliance

While traditional PCBs may contain halogenated flame retardants, these materials pose environmental and health risks during end-of-life disposal. When incinerated, halogenated materials can release dioxins and other toxic byproducts—substances the EPA classifies among the most hazardous chemicals known.

The key benefits of switching to halogen-free PCBs include:

Reduced Environmental Impact: Cleaner disposal and recycling processes without toxic off-gassing.
Improved Worker Safety: Lower risk of exposure to harmful fumes during manufacturing and recycling.
Regulatory Alignment: Meets stringent global standards including RoHS, WEEE, and EU directives on hazardous substances.
Corporate Social Responsibility (CSR) Support: Tangible action for companies with environmental commitments or green product lines.

It’s important to note that halogen-free PCBs are suitable for virtually any application where standard FR-4 boards are used—from consumer electronics to industrial controls—with only minor variations in dielectric and thermal properties.

Halogen-Free Material Specifications

We fabricate halogen-free PCBs using certified eco-friendly materials. Our standard substrates include:

Material	Tg (DSC, °C)	Td (Wt, °C)	CTE-z (ppm/°C)	T260 (min)	T288 (min)
S1155 (FR-4)	140	380	41	60	60
S1165 (FR-4)	170	360	40	60	15

Tg (Glass Transition Temperature): Higher values (170°C) for thermal-demanding applications.
Td (Decomposition Temperature): Indicates material stability under extreme heat.
CTE-z (Z-axis Expansion): Critical for plated through-hole reliability.
