FPC Specification Selection

Delivery format !

You could choose single piece to delivery. Or you choose “Panel by KingCredie”: boards be made panel format by our factory. Or you choose “Panel by Customer” :customer supplied panel format and requirements.

Individual PCB size!

Please input the maximum width and length of your PCB design.

x
mm
Quantity !

The number of boards/panels required.  Note! If you choose "Panel by Customer", then this is the number of panels.

PCS
PCB Type !

Choose the type of board, Flex or Rigid-flex boards.

Flexible PCB
Rigid-Flex PCB
Number of Layers !

The number of conductive layers.

1 Layers
2 Layers
3 Layers
4 Layers
5 Layers
6 Layers
Material Details !

The adhesiveless polyimide has longer bending life than the conventional polyimide. But its disadvantage is too expensive cost. If you not need bend the board frequently, we suggest the conventional polyimide, and choosing the material by the factory.

FR4-Tg 135C & PI
FR4-Tg 170C & PI
Board Thickness !

The finished PCB thickness.

Tips: The thickness here does not include the stiffener thickness of the flex part. 

Tips: That we may charge additional fees if there is a specified lamination structure.

Tips: If it is a flex-rigid PCB, the thickness here refer to the total thickness of rigid pcb part.

Electrical Test !

If it is flying probe test, we will charge the testing cost again when you repeat to order this board. If it is fixture test, we just charge the testing cost one time. When you repeat to order this board, we will not charge the testing cost again.

Unusual PCB Featrures (Impedance Control,Air Gap,Roll Anneal Copper Foil ,BGA,Single Side Double Access,Double Sided Tape...)

Impedance Control !

Single line impedance tolerance +/-10%, minimum +/-5 OHMS; Differential impedance tolerance +/-10%, minimum +/-8 OHMS

Yes
None
EMI Shield Film !

Electromagnetic shielding film also called EMI protection film, or absorbing material which mainly used to weaken or eliminate the effect of electromagnetic interference for the internal wiring, through cutting process and pressing on the free-adhesives FCCL or on covering membrane. The price of EMI is highly affected by the brand and the area, so the final price may be changed.

Single Side
Double Side
None
Single Side Double Access !

Applied with single sided material to make pattern but make some window on base film and add on cover layer on pattern top. The final products will have single layer copper but two side access possibility. 

Yes
None
Air Gap !

The type of Air Gap Structure uses two(or more) single-sided flex circuits (or double sided flex circuits) and applies pre-punched dynamic area adhesive in between to achieve high-flexible demand.

YES
NO
Copper Type !

ED copper has better conductivity than RA copper. While as for extensibility, RA copper is much better than ED copper. The price of RA copper is expensive. If the flex board needs to be bendable a lot, RA copper will be a good choice. Otherwise, we  suggest to use ED copper with high electrical conductivity.  

Electrolysis Deposition Copper Foil
Roll Anneal Copper Foil
Double Sided Tape !

The double Sided adhesive pasted on the FPC is used for following fixing function.

The common models: 3M467MP, 468MP, 3M8853, 3M9077. Please note that if the boards need pass the high temperature wave reflow soldering, you need use 3M8853, 3M9077.

3M8853, 3M9077 can be repeated to put in high temperature wave reflow soldering, they can bear temperature more than 250 degrees.
