Eine ultimative Anleitung, um den Unterschied zwischen flexiblen und starren Leiterplatten zu verstehen

flexible pcb manufacturers

Hersteller in den Sinn,  when you hear the word flexible board. The thought which came first into your mind must be “a board. Which is flexible and have bending properties? But there are many doubts and confusions about it. In addition, many thoughts come into your mind.

Zum Beispiel:

  1. In was für einer Situation verwenden Sie es?
  2. Treffen Sie Vorsichtsmaßnahmen, wenn Sie es verwenden?

Einführung-flexible Leiterplattenhersteller

In this article, we will completely guide you about flexible boards. We will also give you the complete info about the features of flexible boards. For those who are not aware of what flexible boards actually are.

Moreover, we will also explain the features of rigid boards as opposed to “normal printed boards”. And will provide you many instructions and precautions in order to use them.

flexible pcb board History

The history of flexible printed wiring boards is shorter in comparison of rigid printed wiring boards. And it appeared in the 1960s in the United States. They made it as a lightweight and highly reliable printed wiring board. They actually had made it for use in the aviation and aerospace industries.

Nowadays it has been used in almost all mobile devices like:

  • Smartphones
  • wearable computers

Its advantage is that it is very thin and light.

 What is a flexible board according to scientific definition?

The classification of printed circuit boards according to the hardness of the material is as follows.

  • Rigid board
  • Flexible board (FPC board)
  • Rigid flexible board

What is the rigid board? Flexible pcb manufacturers explains

The rigid board is like the one in the photo above. Although Hersteller flexibler Leiterplatten make it with various materials, but it is a rigid board. It’s a substrate you often see. There are lots of electronic components on board. Which has been connected by wiring?

Furthermore, there is a board called a rigid flexible board. And it combines a rigid board and a flexible board.

Als Material des flexiblen Substrats verwenden Hersteller eine Kunststofffolie wie Polyimid. Und wie der Name schon sagt, ist es sehr flexibel. Flexible Leiterplattenhersteller  können es leicht biegen. Daher wird es häufig zum Bewegen von Teilen wie Scharnieren elektronischer Geräte verwendet.

Überraschen Sie Geräte, die nichts mit Kabeln ?


  • Displays für PCs
  • elektronische Wörterbücher

Ich habe mich gefragt, wann ich keine Kenntnisse über flexible Boards habe. Aber eines Tages, als ich das elektronische Wörterbuch kaputt machte, kam so etwas wie eine braune Tafel aus den Angeln. Und zum ersten Mal: ​​"Ich erinnere mich, dass ich überrascht war."

Höchste Eigenschaften von flexiblen Platinen, die von Herstellern flexibler Leiterplatten entwickelt wurden

(1) Weich

This is as I wrote from the beginning. Using its flexibility, it is also used in the following devices:

  • computer hinges
  • printer heads
  • HDDs (hard disk drives).

(2) Light

Since the material is a thin film. So, flexible pcb manufacturers can develop it very much lighter than a rigid substrate. Its advantages are used in industries such as:

  • Automobiles
  • Aviation
  • space

 (3) Price is high

However, it is more expensive than the rigid board. Actually, flexible boards had often used as wiring without expanding components. There are many cases where it is not comparable to the prices of rigid boards but the Hersteller flexibler Leiterplatten think that, “flexible boards are expensive”.

How many points are there to note while using a flexible board?

Actually, there are two main points to note when using a flexible board.

  • Flex resistance
  • Component mounting

Flex resistance

The biggest purpose of using a flexible base is to bend it. But it is not necessary to bend it many times. The flex resistance changes depend on the design as well as Hersteller flexibler Leiterplatten product specifications.

Manufacturer believes that a smooth pattern with as few corners as possible is good.

Component mounting

Since, flexible substrates are thin films and mechanically weak. So, a plate called a reinforcing plate is often attached below electronic components.

The main characteristics of this board made are thinness and softness. Even if flexible pcb manufacturers bends but its electrical characteristics do not change. It has the advantage that it can display its performance. It uses a base film. This is a thin-film insulator. And it has an adhesive layer and conductor foil laminated on top of it?

Flexible pcb characterristics

Flexible bases are characterized by their shape and usage. It is a base with a high degree of freedom. Because it can be bent due to its thinness and softness. And these are its main features.

Moreover, since the electrical characteristics do not change even when bent. So, it has the advantage of maximizing the characteristics. Using this feature, flexible pcb manufacturers explain that it is used as a connecting cable that connects the following:

  • moving parts
  • bent parts
  • between boards and units

That is required to be thin and lightweight.

As well-known examples, it is also used in many devices like:

  • keyboards
  • calculators
  • LCD monitors
  • Printer heads.

Moreover, it is almost always used for moving parts such as:

  • foldable mobile phones
  • three-dimensional circuits

And three-dimensional circuits such as camera lens parts. This base is widely used in space development and air aviation. Because there is a special need for weight loss.

The structure of flexible board recommended by flexible pcb manufacturers

There are basically two main types of structure of flexible board.

  1. Single-sided structure
  2. Double-sided structure
  3. Flex rigid structure
  4. Multilayer flexible substrate (FPC) structure
  5. Single-sided structure

It is mainly used in places with a lot of movements. Its special feature is that it is specific in the following methods like:

  • thinness
  • flexibility
  • lightness

Similarly, it can also be used in narrow spaces where it is difficult to realize. Of course, it has high durability and manufacturers can use it without problems even when they fold and move it a lot.

  1. Double-sided structure

Flexible Leiterplattenhersteller use it when they want to enhance functionality. The feature is that it is also suitable for high density. And it can also improve the degree of freedom of design. And improve also the function when you want to make more complicated circuits such as cross wiring.

However, unlike the one-sided structure, the movable durability is reduced.

How flexible board is different from rigid board?

Flexible and rigid boards have similar basic processing processes. And in which copper foil of copper clad laminate is chemically engraved to form a circuit. The through hole structure comes in the same way.

The main difference in the arrangements and processing procedure is the protection of the circuit surface. Rigid boards are typically printed with solder masks. However, Hersteller flexibler Leiterplatten layer flexible boards with a plastic film called a Coverley.

How flexible pcb manufacturers use flexible board?

The manufacturers use flexible board as a connection cable. And it connects between boards and units. After connecting between boards, between units, etc., it is possible to differentiate between two types of wiring methods. And it depends on the application.
It is divided into “fixed wiring” that does not move after connecting to equipment. And “movable wiring” that repeatedly bends such as the hinge of a mobile phone.

  1. Flex rigid structure

This structure includes a rigid board into a flexible board (FPC). Flexible Leiterplattenhersteller use a sandwich structure. And in which a flexible substrate (FPC) in the middle layer is sandwiched between rigid substrate materials in the front layer (front and back).
It is defined in that the rigid part has the same mechanical strength as the rigid board. In short, it is a product that combines the two:

  • a rigid board
  • a flexible board (FPC)

This enables connector that hassles and three-dimensional wires.

  1. Multilayer flexible substrate (FPC) structure

Multilayer flexible board (FPC) is a product in which all layers are made of flexible material. This structure has an advantage in the following manners like:

  • Lightness
  • thinness
  • high density.

Flexible Leiterplattenhersteller  erklären, dass sie auch eine ausgezeichnete Wärmebeständigkeit aufweisen. Weil es die gleiche Materialzusammensetzung hat. Es hat zum Downsizing und zur hohen Funktionalität von beigetragen

  • Mobiltelefone
  • Digitalkameras usw.

Und es wird auch in verschiedenen Ausrüstungsbereichen eingesetzt.
