The composition of Fr-4 Rigid PCB

The construction of polyimide rigid boards is done through the use of a combination of different types of layers that offer heat resistance to the board. There are many layers involved in the final composition of the PCB board and all these layers are described in the below section:

  • 基板
  • ソルダーマスク
  • 銅の層
  • シルクスクリーン
リジッド基板の構成

基板

At the starting bottom layer or base, the substrate layer is essentially the foundation of the PCB and the initial step for rigid board construction. FR4 material is used for the creation of substrate and the rigid nature of FR4 is what increases the rigidity of the overall board. Alongside FR4, different materials including phenolics and epoxies are also used for the creation of substrate. However, such materials are mostly not used since they do not offer as much strength as Rigid FR-4 PCB but are used in some projects where a lower price is required.

ソルダーマスク

For protecting the various PCB層 and paths created on the board, the use of copper as the solder mask is used. Solder mask works as an insulator and protects the copper layers from oxidation in other conditions. The solder mask of rigid PCB typically comes in distinct colors like green, black, blue, pink etc., but a green color is mainly used.

銅の層

When the creation and application of substrate layers are complete, a copper layer is placed on the substrate. These copper layers work as the lamentation for the substrate and protect the substrate from heat and other environmental conditions. The best and most important feature of the copper layer is that it helps in the transmission of data among the many components and layers of the board. It is necessary to know the manufacturer’s rigid PCB copper thickness capability in detail before choosing a service provider to serve you. In some projects, double-layer rigid boards are used, which have copper layers on both sides whereas, in lower-cost projects, single-layer boards are commonly used but can affect the overall operation of those projects.

シルクスクリーン

The last and topmost layer of the board is the silkscreen layer and on this layer, there are oftentimes a vast array of numbers and symbolic representations (component identification numbers, symbols, schematics, etc) that can be printed on the rigid board to assist in the use, assembly (soldering) or connection of electronic components for the creation of projects.

リジッドリピーターPCBA

Repeater Rigid PCBA

Since signal transmission of wireless electronic devices has a common disadvantage of an increase in the distance leading to a weakening in the signal, this may lead to an overall diminishing of signal transmission capabilities in a multitude of electronic devices. However, the emergence of repeaters PCBA serves as a well-suited solution to this problem. High-frequency and high-density rigid PCBs play a key role in the internal structure of a repeat and through the ability of these circuit boards to amplify signals and compensate for signal attenuation, the signal transmission distance can significantly increase.

Rigid Medical Device PCBA

Rigid PCBs used in the medical industry have a higher degree of contrast in manufacturing difficulties due to their wide uses. In the case of lighting components, for example, the difficulty of manufacturing these medical circuit boards is comparatively low with a far lower price point that even ordinary rigid PCB manufacturers can produce them easily. On the other hand, products such as X-ray    machines, CT scans and implantable microelectronics require more complex manufacturing techniques and require a professional turnkey rigid circuit board assembly company to achieve their maximum quality. FS Technology has been seeking technological breakthroughs in high level rigid board manufacturing and assembly and began to introduce skilled engineers in 2019 that are specifically trained in these fields. We believe that all your difficult projects can be completed     with the assistance of our engineers’ rich knowledge and responsible attitude. The current manufacturing capabilities of FS Technology support the creation of rigid PCBAs for the following medical electronic devices:

  • Handheld Wireless Controllers
  • Laboratory diagnostics tools (laboratory blood diagnostics, high-pressure liquid chromatography and dialysis)
  • Imaging and monitoring devices (ultrasounds, CTs, MRIs, PET scans, X-rays and patient monitors)

Comparison of other boards with Rigid PCBs

Choosing the printed circuit board that is suitable for your project can highly promote the advancement of the project. When discussing what kind of circuit board is suitable for your project, in addition to paying attention to the characteristics of the materials used, you also need to consider the hardness or durability of the PCB. The following from FS Technology will compare rigid, flexible and rigid-flex PCBs を選択すると、より適切な PCBタイプ.

リジッド基板とフレックス基板の比較

Simply from the names of the two types of boards, the most obvious difference between rigid and flexible PCBs is in the softness and hardness of the boards. Rigid PCBs are essentially circuit boards built from a rigid base material that cannot be bent or structurally altered after customization, while flex PCBs are built on flexible bases that can purposely be bent, twisted and folded. Although both rigid and flexible PCBs are widely used in electronic equipment and have the same basic purpose, we cannot ignore the advantages and disadvantages of their performance.

  • Lower cost of rigid PCB manufacturing and assembly (PCBA): The predominant drivers of PCB manufacturing and PCBA cost include the material used, number of layers, size, etc. Although both board types are manufactured in a similar way, flexible   PCBs are commonly more expensive than rigid PCBs under the same circumstances. If you consider the project profits, FS Technology recommends that you first conduct PCBA cost driver analysis and can reduce the overall project cost through rigid materials.
  • Additional protection: Due to the circuit pattern of flex PCBs being exposed, turnkey manufacturers have to use a cover film instead of a solder mask during its creation process. On the other hand, rigid PCBs do not have this concern and only need the normal プリント基板製造工程.
  • Flexibility: Even if rigid boards have better reliability, they are powerless in the face of three-dimensional space, so it is not suitable for some electrical projects that require flexibility of circuit boards.
  • Circuit board layers: We know that the number of high-level PCBA is equivalent to more wiring space in its internal structure. Furthermore, the higher the number of layers of the multi-layer board, the less the influence of electromagnetic interference between the      layers and hence, the interference between signals is reduced. Due to the differences    between the two board types, rigid materials are more suitable for building rigid double-sided, four-layer and six-layer PCBs, while flexible boards are more for single-layer PCBs.
  • Electronic projects: Some small-size devices and electronic modules such as computer keyboards and toys make use of rigid PCBs but for high-operation projects, FPCBs are used as they minimize the use of hardware connectors and provide a reliable solution for most connection failures.
まとめる

Polyimide rigid PCBs are a category of boards that come with a nonflexible structure and cannot be modified to another shape easily. If high pressure is applied to these boards, it is likely that the boards will break. Its design and structure are a combination of different types of layers such as the bottom substrate layer, followed by the copper solder mask layer and at the top, a silkscreen layer that is important in ensuring that electrical connections are established for the different   projects that the board is assembled for. These boards, contrary to other types of boards, can be created in single, double and multiple layers, depending on the project requirements. Their main feature is that when these rigid circuit boards are produced, there is no chance to modify them and convert them into another form post-manufacturing.

In conclusion, detailed explanations have previously been done focusing on rigid PCB boards that will help you to get an in-depth overview of the features of this PCB type. Rigid boards have increasingly become a very common aspect in the electronics industry and engineering projects because of their giving nature that enhances their use in the computer industry. The versatility of these boards allows for different projects, especially with computer boards due to their rigid and solid structure. Even when a large number of components are configured and assembled on complex rigid PCBs, the board can handle all components accurately, providing the necessary strength to both the board and all needed components on the board.
