Understanding Halogen-Free Substrate

According to the jpca-es-01-2003 standard, the copper clad laminate with chlorine (кл) and bromine (Br) content less than 0.09% wt (weight ratio) is defined as halogen-free copper clad laminate. (В то же время, total Cl + Br ≤ 0.15% [1500ppm]).

What is Halogen?

Halogen is a nonmetal element of group VII a, which includes fluorine, chlorine, bromine, iodine, and astatine. Среди них, astatine is a radioactive element, and the halogen commonly referred to is fluorine, chlorine, bromine, and iodine. Halogen compounds are often used as flame retardants: PBB, PBDE, TBBP-A, печатная плата, hexabromododecane, tribromophenol, short chain chlorinated paraffin, и т. д., which are used in electronic components and materials, product shells, plastics, и т. д.. This kind of flame retardant can not be recycled, and will release harmful substances in the process of combustion and heating, threatening the health of human body, the environment and the next generation.

Halogen Free Requirements

В настоящий момент, different products have different limit standards for non-halogenation requirements:

• If there is no halogenated wire and cable, the halogen index is: all halogen values ≤ 50ppm (according to regulation prEN 14582);
• The content of hydrogen halide gas produced after combustion is less than 100ppm (according to the regulation en 5067-2-1);
• The pH value of hydrogen halide gas generated after combustion is dissolved in water ≥ 4.3 (weak acidity) (according to the regulation en-5 0267-2-2);
• The light transmittance of the product after burning in a closed container is greater than or equal to 60% (according to regulation IEC 61249-2-21);
• Requirements are as follows: chlorine < 900 ppm; bromine < 900 ppm; total halogen < 1500 ppm.
