The main specifications of this board is double
sided board, substrate is F4B, DK at 2.65, 210mm long by 115mm wide, 1.6mm
finished thick, finished copper 3oz, no solder mask no silkscreen, and surface
finish is immersion gold.
Let’s see the stack up.
Top layer and bottom layer are3oz copper
finished. F4b dielectric material is in the middle of 2 layers copper, showing
dielectric constant at 2.65
From the photo of this board, the track is
thicker than normal boards; surface finish is immersion gold and no solder mask
and silkscreen.
