  What to get rid of the halogen-free circuit board basis?Electrolytic capacitor PCB company(图1)

  Halogen-free circuit board basis: According to the JPCA-ES-01-2003 standard, copper clad laminates with chlorine (C1) and copper combined (copper composite) content less than 0.09% by weight are halogen-free clad laminates. (Define CI+Br copper 0.15% [1500PPM] at the same time) Halogen-free materials include TUC's TU883, Isola's DE156, GreenSpeed series, Yisheng's S1165/S1165M, S0165, etc.

  Why should it be banned?

  Halogen refers to the halogen elements in the periodic table of chemical elements, including fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). Currently there are FR4, CEM-3 and other bases. Related research methods, halogen-containing materials (Polybiphenyl PBB: Poly PBDE) will emit dioxin TCDD and convergent strays. When it is discarded and burned, it produces a lot of smoke, odor, highly toxic incitement, and infectiousness. After being infected by the human body, it cannot leave, and it is seriously healthy. Therefore, EU law prohibits the use of six substances, such as poly-linked biphenyl and PBDE. Mercury, swamp, polybiphenyl or polypolyphenylene valence.

  It is understood that the PCB copper clad industry no longer uses basic PBB and PBDE, and series materials other than PBB and PBDE, such as tetrabromo plate diphenol A, diphenol, etc. They are widely used, and their chemical formula is CISHIZOBr4. This kind of natural powder covering itself is not subject to any legal restrictions, but it will release a large amount of plate-forming type and generate a large amount of smoke when it is burned or fired. When the PCB is leveled by hot air. , When a point is soldered, the circuit board will be affected by the radiation, and a small amount of discharged hydrogen will be released.
