Bagaimana cara kerja komponen PCB rigid-flex yang berbeda?


rigid flex pcb manufacturers

It is the age of the 4th industrial revolution. If we want to walk with the demands of the time, we have to accept the significance of technology in our life. Generally, this article will tell you about one of these technical tools on which major systems of the industry are looking for sound progress and development. I am going to explore information about Rigid-Flex PCB manufacturer’s technology. It is worth able to note that the 1st computer in the world used Rigid-Flex PCB technologies. In the modern era, computing devices, medical equipment, space vehicles, textile technology are a few examples that are using Rigid-Flex technology commercially.

What is Rigid-Flex PCB?

Rigid-Flex PCB is a printed circuit that is a hybrid of rigid and flexible circuit substrates together. This PCB has the qualities and characteristics that are superior to traditional circuit PCBs. Subsequently, the most important benefit of this PCB is that it is free from using cables and connectors. However, it can connect the circuits electrically.

How do rigid-flex PCB manufacturers improve performance issues?

  • Loss of signals is no longer a problem. It improves the quality of signal transmission.
  • Rigid-Flex PCBs are able to generate the following accomplishments:
  • Now impedance is under control.
  • Many problems to connection fade away.
  • Due to the electrical connection, the weight of the system becomes so small.
  • Many Other components find a place to be attached.

Produsen PCB Rigid-Flex menyediakan zona berbeda pada PCB. Lebih lanjut, zona-zona tersebut memiliki lapisan dan material yang berbeda. Beberapa zona kaku yang memiliki lebih banyak lapisan sementara yang lain merupakan zona fleksibel dengan lapisan lebih sedikit.

Struktur PCB Flex-kaku

Rigid-Flex PCB memiliki struktur yang unik dan serbaguna. Ini memiliki empat jenis lapisan dasar. Keempat lapisan tersebut adalah sebagai berikut:

  • Lapisan dasar
  • Lapisan konduktor
  • Lapisan perekat
  • Lapisan isolasi

Apa Fungsi Lapisan Perekat? - produsen PCB rigid-flex recommendation

Fungsi dari lapisan perekat adalah untuk menghubungkan semua lapisan menjadi satu. Lapisan dasar merupakan lapisan utama untuk memberikan kelenturan pada rangkaian. Arti penting sifat listrik ada karena lapisan ini. Banyak bahan yang disarankan untuk digunakan sebagai lapisan dasar tetapi bahan yang paling baik adalah polimida. Secara bersamaan, material ini memiliki sifat yang sangat unik yang mengelilingi area konduktivitas listrik, mekanik, kimia dan termal. Ketebalan lapisan dasar berkisar antara 12 dan 125 mikrometer. Selain itu, fleksibilitas rangkaian secara langsung berkaitan dengan lapisan rangkaian yang lebih tipis. Semakin tipis lapisan alasnya, semakin fleksibel sirkuitnya.

Bagaimana proses kompresi dan peregangan pada PCB kaku-fleksibel?

Ketika sirkuit mendapat tikungan, material luar akan meregang untuk mengelilingi radius. Dengan cara ini, ketegangan dihasilkan. Namun, bahan bagian dalam mengompres untuk mengimbangi menyusut. Daerah rangkaian di mana ada sedikit atau tidak ada tegangan disebut sumbu tikungan netral. Ini adalah wilayah di mana tidak terjadi kompresi atau peregangan.

Generally, produsen PCB rigid-flex tell us about a lot of PCB developing techniques, it is thought that the neutral bend is in the middle of the Rigid-flex PCB circuit. But it is not true. It can be braced to another position by composition and area surrounded by the material. The Rigid-flex PCB manufacturers are experts and innovative enough that they manipulate a package for the different designs of the circuits. Hence, they completely and elaborately take note of all the characteristic features of the Rigid-flex circuit. An ideal drawing provides a flat panorama with all the particular dimensions.

Design Rules For produsen PCB rigid-flex

To become the distinguished produsen PCB rigid-flex is not an easy task. They have to keep in mind the essential rules for the manufacture of these circuits. Moreover, the uniqueness and versatility of these circuits are due to this design that is wisely determined by the manufacturers. As these circuits cover the area of both flexibility and strength, the manufacturers are here free to place the components to the flexible points or areas of the circuit.

Perangkat produsen PCB rigid-flex innovative product design demands for the new and productive approach. In this regard, a few challenges are in the line regarding routing and holes. Surface pads and through holes can face stresses even in the presence of true and accurate location of components. Bend lines are the regions or points on the circuit that affect routing.

That is why we can’t place the components near the bends. The method to better minimize the effect of these bends is to use through holes plating and more overlays. The use of canonical polygons is helpful in galvanizing and improving flexibility. Moreover, the use of curved traces is also helpful in this regard but keep in mind that it should not lie in 45 or 90 degrees.

How to find the best rigid-flex PCB manufacturers?

As produsen PCB rigid-flex circuit utilizes multiple layers, 3D design; the manufacturer team has to check the essential rules of formation unanimously and improvingly. In short, the more teamwork is utilized in the technique, the more successful design will be produced. Remember that teamwork should be applied in the very initial stage to start a creative design and should be followed throughout to end with a rewarding design of the Rigid-flex PCB circuit.
