12 Layer Rigid-Flex PCB with 2 Layer Flex PCB

Model: Rigid-flex board-12 Layer

The design of a 12 layer rigid-flex PCB with 2 layer flex PCB is similar to that of the 10 layer rigid-flex with 2 layer flex PCB. However, the addition of 2 layers (i.e. the 11th and 12th layers) make the design a bit more complex than its 10 layer counterpart. The 2 layer flex PCB design of this circuit board makes it more flexible for manufacturing. Another benefit of this printed circuit board is that you can use exposed pads, and access holes on both the sides of the flex, and vias can be covered on either side. The 2 layer flex PCB consists of an insulating layer between the conductive layers. Plated through holes are used to create connections between the layers.

We can manufacture these PCBs, with a board thickness of 0.5 mm ~ 3.0 mm. The copper thickness can vary from 0.5 OZ to 6 OZ. The finish thickness of the board is 0.2 mm (flex). We use FR4 and polyimide materials for these boards. For designing a custom PCB, you can choose from surface finish options, which include OSP, HASL, and immersion gold.

We have utilized a combination of FR4 and Polyimide materials. These materials support excellent thermal stability, mechanical properties, and electrical insulation. To ensure that heat distribution is also well achieved, we have added a heat sink component to the design of the PCB. Our fabrication capabilities allow us to provide PCBs with board thickness ranging from 0.02″ to 0.12″. Two layers are dedicated to power and ground. The power and ground planes allow for better distribution of electrical power. These features, along with high quality fabrication, makes the 12 layer PCB a perfect choice electrical and mechanical applications.

What is rational is actual and what is actual is rational - Georg Wilhelm Friedrich Hegel.

PCB is widely used in our household appliances, industrial production machinery and equipment. However, in general, PCB refers to rigid PCB. Although rigid PCB is the most widely used, but with different application scenarios and functional requirements, rigid-flexible Printed Circuit Board also emerged.

Rigid-flexible PCB has been widely used and developed, which is inseparable from its superior performance.

With the development of PCB design and production technology, there have been Double-sided rigid-flexible PCB, multi-layer rigid-flex PCB(3 Layer, 4 Layer, 5 Layer, 6 Layer, 8 Layer, 10 Layer, 12 Layer, 14 Layer), etc.

What's "Rigid-Flex PCB"?

Rigid-Flex circuit is made from a combination of a PI flex material sandwiched between FR4 epoxy or Polyimide rigid layers.

Rigid-Flex circuit boards are composed of a combination of rigid and flexible circuit boards that are permanently connected to one another.

Drilling and plating are processed throughout the sandwiched areas.

Flex-Rigid PCB is a good solution for dynamic application. The whole cost can be profitable and increase the reliability of the device.

Use of Rigid-Flex circuit boards can reduce the total cost of the final product.

Depending on the application, the complete Rigid-Flex circuit board may be manufactured either symmetrically with inward flexible layers, or asymmetrically with outward flexible layers

Why Rigid-flex PCB is widely used?

Rigid Flex PCB Design

Different applications determine the design idea of rigid-flexible PCB.

New product designs coupled with improved flex circuit technologies have introduced new design rules for rigid-flex PCBs.

When you design rigid-flex PCBs, think in terms of electromechanical factors that affect both the flex circuit and the rigid board. 

Before we move onto the proper design of such a PCB, you must also keep certain factors in mind. Technology is always changing and evolving as the years go by; this means that people come up with new designs and methods of creating a Rigid Flex PCB are and will always be different, so there is no absolute way of making a rigid Flex PCB.

Moreover, depending on the application of the rigid flex and its purpose, the design and layout can be very different from the standard design, so keep in mind that the purpose of the PCB can significantly affect the design of the PCB.

The thickness of a Rigid Flex PCB is very subjective, as depending on the purpose of the build the difference can be minor or incredibly significant. The average board thickness for a rigid Flex PCB can be somewhere between 0.2mm and 0.4mm. 0.2mm is the average thickness of a single layer PCB circuit, and 0.4mm is the average thickness of a PCB with nearly 4 layers.

When rigid-flexible PCB design, the materials used and PCB assembly should also be considered.

Only when many factors are considered comprehensively to create a Rigid Flex PCB that is both durable and flexible. All of these methods combine to make an effective and efficient circuit board.

Rigid Flex PCB's Technology and manufacturing Process

The technology that most manufacturers use on a PCB differs depending on the manufacturer, type of PCB, and the efficiency of the PCB. The efficiency of the PCB is one of the unique attributes about a rigid flex`s PCB, as depending on the task of the PCB the technology that a designer uses can differ significantly.

The manufacturing process of every PCB starts with stacking various layers of metal and other circuit boards. This part of the process is called the stack up.

The stack up is the process of placing the layers for the rigid flex printed circuit board. Depending on the Rigid-flex circuit board the stack up can be of one, two, or four layer(s), and layers increase by the object`s application as well as its uses.
