What are the Characteristics of Halogen-free PCB?
According to JPCA-ES-01-2003 standard: Copper clad laminates with chlorine (C1) and bromine (Br) contents less than 0.09% Wt (weight ratio) respectively (at the same time, the total amount of CI+Br ≤ 0.15% [1500PPM]) are defined as halogen-free copper clad laminates. So what are the characteristics of halogen-free PCB? 1. Environmental P rotection Halogen-free PCB board realizes environmental protection and non-toxicity of PCB by replacing or replacing harmful elements. 2. F lame R etardant Most of the halogen-free materials are mainly phosphorus -based and phosphorus - nitrogen -based . The polymer resin containing phosphorus and nitrogen compounds will form a carbonized film when it is burned, which can isolate the burning surface of the resin from contact with the air, so that the fire can be extinguished and the flame retardant effect can be achieved. 3. ...
