How time flying! 2011 Chinese Lunar Spring Festival will come soon. In the past time, we have run successfully by the support from our customers, suppliers, friends, colleague. We hope 2012 will be much better, and every body can enjoy the warm Spring Festival.
Here is our holiday arrangement:
Closed: Jan 16th-Jan 31st
Resume: Feb 1st
For orders of normal 1Layer FPC , dual access flex circuit and 2Layers flex circuit release in this week, we will make and ship before our holiday; for Rigid-flex circuits, or multi-layers flex circuits, or order receive in Jan will be postponed to be shipped in Feb.
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.
