Surface treatment: ENIG 4 layers
Board Thickness: 0.9mm
Min hole : 0.3mm
Min line width/ space : 0.12/0.12mm
Particularity : Rogers 4835+FR4
Application: power supply
This board is panalized by two pieces, which the board thickness is only 0.9mm.
This board is used by the special material Rogers 4835, Rogers radio frequency sheet RO4835 adds anti-oxidant material, which is stronger than RO4350B.
ENIG is a thick nickel gold alloy with excellent electrical properties on the copper surface and can protect PCB for a long time.
And acts as a rust barrier, which can be useful and achieve good electrical performance in the long term use of PCB.
What’s more, it also has environmental tolerance than other surface treatment processes do not.
