What is 2-Layer Flexible PCB?

In essence, the 2-Layer Flexible PCB deploys a flexible laminate for its base material. It is composed of two (2) conductive layers that are integrated into a polyimide base.

It has become popular because of its enhanced impedance control and reliability. They are versatile boards that can be applied in complex circuitry.

They are widely deployed in repeaters, digital cameras, cell phones, LED displays, and wireless floating heads. Also, it comes with various thickness selections from 0.15 mm up to 3.0 mm and has a maximum panel size of 18” by 24” board.

Its stack-up has a central base film referred to as a substrate, then two copper foils, up to four adhesive layers, and two protective coatings. Call us right away to obtain our decently priced, high-quality PCB items!

Manufacturing Layout of a 2-Layer Flexible PCB

Manufacturing Layout of a 2-Layer Flexible PCB

As its name implies, 2-Layer Flexible PCB is composed of two conductive layers that may or may not have plated-through holes in its production. Nevertheless, it is the industry’s most widely preferred type of variation for this particular board.

It has been dominating the production process of this board because of its connections for electronic components since they are accessible on either side of the board.

Thus, placing components on both sides of the board is possible. Moreover, since the layout of this board necessitates protective layers, they can be applied on both sides.

If you wish to avail our enhanced quality 2-Layer Flexible PCB at its affordable price, message us today so that we can further assist you!

Type of Material to Produce 2-Layer Flexible PCB

In this particular board, the common materials utilized are copper, copper foil (rolled and annealed and electrodeposited), and alloys (gold, silver, nickel, aluminum).

The following are the materials that are ideal options for this board:

  • FR4 – It is made up of composite materials. Also, it has constant electrical insulation, can tolerate up to 130°C and has a 4.5 dielectric constant value.
  • Polyester – It offers high tolerance to chemicals and moisture.
  • Polyimide – It is known to be durable and resistant to heat, oils, and solvents. Some of its perks are its high-temperature tolerance and bending strength.
  • PTFE – They are simple to produce and offer an excellent balance between high-temperature stability and heat dissipation.

Therefore, we highly recommend working closely to balance our design specifications and manufacturing alternatives.

We can only provide basic production processes; designing, obtaining essential components, developing, constructing, and inspecting.

We strongly advise messaging us for further details on its procedure.

What is the Cost of 2-Layer Flexible PCB?

Since transparency is one of the virtues we value, we’d like to share with you the estimated cost of producing this particular board.

In comparison to Single-Sided PCBs and Rigid PCBs, the 2-Layer Flexible PCB is more expensive to produce due to its raw materials needed.

There is a variety of reasons that causes the rise in its prices; board type, track spacing, hole size, stiffener, copper thickness, and surface finish.

Nevertheless, if you choose us as your manufacturer, we can offer you the best deals that we have to help you reduce your costs in production.
