Talk about Flex Circuits, FPCB, Rigid Flex, PCBA
Following up with the last article Normal Thickness for 2Layers Flex Circuit (Adhesive), here we’d like to share thickness for 2L flex circuit if using adhesiveless material.
2L FPC Flex circuit thickness (adhesiveless)
We also have other special material, such as 1mil Polyimide + 2OZ (70um) copper adhesiveless, (from Dupont). If you need more information, please contact us.
Different from rigid FR4 PCB, there’re three basic layers for flexible circuits, and various thickness of each maybe used, so people new to that area will be confused to choose a suitable thickness.
Here are four normal thickness for 2 layers (Double sided) flex circuit, and we hope it’ll be useful for the green hand:-)
2L FPC Thickness
2L FPC Thickness
As you can see, there’re adhesive in base for each four basic thickness of 2L (double sided) flex circuits, if you need more thin, then you can use adhesiveless material, and final thickness will be thinner even you use the same copper and Polyimide thickness.
