Meeting Customers from Vietnam–Second Stop at the Flex PCB Factory

Posted on by Love FPC

On October 18, 2018, Customers Son and Nguyen from Vietnam visited Best Technology. At first, they visited our office and would like to know more about the Flex PCB design. So they came to our Flex PCB factory for visiting.

BEST always be your best choice of Flex PCB. And we hope the partnership can enhance our capability to supply our customers with good quality Flex PCBs.

Differences between Roll Anneal Copper Foil and Electrolysis Deposition Copper Foil

Differences between Roll Anneal Copper Foil and Electrolysis Deposition Copper Foil

Roll Anneal Copper Foil (RA copper):

Formation: Roll copper block many times, and then do the annealing treatment with high temperature. The shape of its crystal is lamellar structure.
Advantage: Soft, smooth surface, suitable for flexible PCB and small lines.
Shortage: high cost

Electrolysis Deposition Copper Foil (ED copper):

Formation: Melt copper into dilute sulfuric acid, it becomes bluestone solution.
Through a high electric field, copper attach on the metal drum. With the rolling of metal drum, thin copper foil finally formed.

Advantage: Low cost
Shortage: Unsuitable for small lines; bad bending resistance.
Here is the cross section observation of RA Copper and ED Copper:

Normal Thickness for 2Layers Flex Circuit (Adhesiveless)

Posted on by Peter

Following up with the last article , here we’d like to share thickness for 2L flex circuit if using adhesiveless material.

We also have other special material, such as 1mil Polyimide + 2OZ (70um) copper adhesiveless, (from Dupont). If you need more information, please contact us.

Normal Thickness for 2Layers Flex Circuit (Adhesive)

Posted on by Peter

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:-)

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.
