Frequently Asked Questions about Halogen Free PCB Design
1.What is the substitute for "halogen"?
At present, most halogen-free PCBs are mainly replaced by phosphorus and phosphorus nitrogen
2.What are the properties 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-phosphorus-oxygen reduction resin, the probability of forming hydrogen bonds with hydrogen atoms in water is lower than that of halogens. The water absorption rate of halogen-free PCB is lower than that of conventional boards, which affects reliability to a certain extent.

Thermal stability: The nitrogen and phosphorus content in halogen-free PCB is higher than that of ordinary board, so monomer molecular weight and Tg value increase.

3.What is a halogen-free PCB?
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 made of halogen-free copper clad laminates.
4.What are halogen-free materials?
Halogen-free materials are those that do not contain one group of halogen elements (fluorine, chlorine, bromine, iodine and astat).
