High density interconnected (HDI) PCB, represent one of the fastest-growing technologies in PCBs. Because of its higher circuitry density than traditional circuit boards, the HDI PCB design is able to incorporate smaller vias and capture pads, and higher connection pad densities.
The above board is 6L FPC with HDI. The overall thickness is 1.6mm. Its copper is 1OZ. The cover film’s color is amber and the silkscreen’s color is white. The finishing treatment is immersion AU. Six position need stiffener. All the stiffeners’ thickness is different, and the material is also different.
The Min.line width and space are both 3mil. The Min hole is 0.1mm. This board also has an impedance, so the requirement of line width and space is very very strict. The outline of this board is very strange, so it is easier to do the profile by using mold, not by laser.
