China Halogen-free PCB is a Copper clad panels with chlorine (C1) and bromine (Br) content less than 0.09% Wt (weight ratio) are defined as halogen-free copper clad panels, i.e. PCB halogen-free substrates. Halogen-free PCB Made in China.Halogens refer to halogen elements in the periodic table of chemical elements, including fluorine (F), chlorine (CL), bromine (Br), and iodine (1). At present, flame retardant substrates such as FR4 and CEM-3 are mostly brominated epoxy resins as flame retardants. In brominated epoxy resin, tetrabromobisphenol A, polybrominated biphenyls, polybrominated biphenyl ethers, and polybrominated diphenyl ethers are the main blocking fuels for copper clad laminates, with low cost and compatibility with epoxy resin.
Halogen-free PCB- A Comprehensive Buying Guide. What is it? Halogen-free boards are PCBs that primarily consist of halogen-free copper-clad laminate. We are China Halogen-free PCB suppliers.We accept Customized. This classification is according to the ES-01-2003 - A Japan Circuit Association (JPCA) standard. Examples include a copper-clad laminate with less than 0.09% Wt of a halogen, such as bromine/ chlorine.Cheap Halogen-free PCB,we offer free sample.
Halogen-free PCB materials:
1. Ventec's VT-447
2. ShengYi's S1165, S6015, S1165M and S1550G
3. IT-170GRA1TC by ITEQ
4. Panasonic's R1566S, R1566WN, and R1566.
Also, there are halogen-free substrates that include:
1. Materials with nitrogen and phosphorus instead of halogens
2. Halogen-Free solder mask ink.
Advantages of Halogen Free PCBs:
They have better electrical insulation than halogen-based electrical products.
These PCBs feature a relatively more minor thermal expansion coefficient than halogen retardants.
Additionally, they feature a relatively high glass melting point.
Also, they have better thermal properties (reliability) than their halogen-based counterparts.
Moreover, they are safe for human health as they don't pose health risks upon disposal.
Lastly, they feature slower moisture or water absorption rate.
