Halogen-Free PCB
Halogen-free PCBs refer to printed circuit boards (PCBs) whose substrates, solder mask inks, and other manufacturing materials contain halogen elements such as chlorine and bromine that strictly comply with international environmental standards. Their core feature is the use of halogen-free compounds in place of traditional halogen flame retardants. While maintaining the excellent electrical and mechanical properties of FR-4 and metal substrates, they also achieve low smoke, are non-toxic, and do not release harmful substances such as dioxins during combustion, combining high heat resistance with environmental safety. These boards support complex designs with 1 to 32 layers, with thicknesses ranging from 0.3 to 6 mm, and can achieve 3-mil precision circuitry. Combined with green surface treatment processes such as lead-free tin spraying and nickel-immersion gold, they are widely applicable to new energy automotive electronics, high-end medical equipment, energy-saving home appliances, and demanding consumer electronics. They are a key vehicle for promoting green manufacturing and sustainable development in the electronics industry.
