Description
Technical field
This utility model relates to circuit board technology field, and particularly relating to one can damp-proof flexible PCB.
Background technology
Flexible PCB is a kind of printed circuit board (PCB) made for base material with polyimides or mylar.Be called for short soft board or
FPC, have that distribution density is high, lightweight, thickness is thin, can free bend, fold, wind and the advantage such as thermal diffusivity is good, extensively should
It is used in MP3, MP4 player, computer, digital camera, mobile phone, medical treatment, automobile, space flight and military field.Because FPC uses copper
Foil substrate, so conduction property is splendid.But existing flexible PCB does not has water-proof function, when making moist or be stained with water,
Easily break down, even can be short-circuited, damage other hardware；The most unresolved such problem of prior art.
