The Development Tendency to PCB Board Base Material
There are two tendency on development to PCB base material, they are Halogen free
and Pb free.
The six kinds of disabled harmful material which listed into the forbidden range, the
material of Pb, PBB and PBDE has direct relationship to printed circuit board.
Lead is
used as Tin Lead coating layer which has solderability to the pad on surface of the
printed circuit board, it was formed by hot-level tin-lead solder or electroplating tin
lead.
PBB and PBDE bromide is used as flame retardant of prepreg and copper-clad
laminate of printed circuit board, they were mixed in the resin.
PCB base material: Halogen free sheet
Halogen free base material，also has below other name:
Environmental Protection CCL
Halogen-Free CCL
Green CCL
Halogen/Antimony Free CCL
Environmentally Conscious CCL
Environment-Friendly CCL
Definition of Halogen free base material:
① The performance of flame retardant can meet UL94 V-0.
② Non-Halogen
