Multilayer Printed Circuit Board Electronics Circuit Board Circuit Board Components FR4 Printed Circuit Board

PCB Printed Circuit Board(FR4,4L)

Layers:1-32layer, if the layer is 20L or mare than 20L, will need to review the board.

The max finish panel size is 740* 500 MM, but if panel side >600 MM, will need to review it.

The Minimum panel size is 5 * 5mm.
Raw materials of Printed circuit boards include FR4, Rogers,Halogen-free, High TG materials...

Blind and buried holes lamination press times: Press with same core ≤3times (>3 times needs to review)
PCB thickness capability is from 0.2~4.0mm, if thickness is less than 0.2 mm, or more than 4 mm, will need to review it at first. 

PCB copper thickness capability: Inner layer≤ 6 OZ( but copper thickness ≥5 OZ for 4L,≥4OZ for 6L,≥3OZfor 8L and above shall be reviewed)

Outer layer copper: ≤ 10 OZ(≥5 OZ needs to review)

Bow and twist tolerance is 0.075%.
