Halogen-free PCB printed circuit boards have low water absorption and meet the requirements of environmental protection, in other performance can also meet the quality requirements of PCB board.
Halogens are halogens in the periodic table, including fluorine, chlorine, bromine and iodine. Halogen-free board is to replace or replace these harmful elements to achieve environmental protection and non-toxic PCB.
PCB manufacturers, PCB designers and PCBA manufacturers explain what halogen-free PCB is, and how much relevant knowledge do you know
Circuit board manufacturers and circuit board designers explain the production experience of halogen-free PCB
Insulation: Since the halogen is replaced by P or N, the polarity of the epoxy molecular bonds is reduced, which improves the insulation resistance and breakdown voltage.Water absorption: Due to the relatively low electrons of N and P in the nitrogen-phos
According to JPCA (Japan Circuit Association)-ES-01-2003 standard: CCL with chlorine (Cl) and bromine (Br) content less than 0.09% Wt (weight ratio), respectively, is defined as halogen-free CCL (while CI+Br Total ≤0.15% [1500PPM]). Halogen-free PCBs are
The halogen -free PCB has the following characteristics: 1. TG high and conventional PCB board. 2. There is a lower water absorption and high stability. 3. More adapted to environmental protection requirements. 4. Suitable for the production of impedance
