ဘယ်လိုတင်းကျပ်သော flex PCB ၏အစိတ်အပိုင်းများကဘယ်လိုအလုပ်လုပ်သလဲ။
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 တင်းကျပ်-Flex ကို 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.
Rigid-Flex PCB manufacturers provide different zones on a PCB. Furthermore, these zones have different layers and materials. Some zones are rigid that have more layers while others are flexible zones with fewer layers.
Structure Of Rigid-Flex PCB
တင်းကျပ်-Flex ကို PCB has a unique and versatile structure. It has four types of basic layers. These four layers are the following:
- The base layer
- A conductor layer
- An adhesive layer
- An insulating layer
What is the function of the Adhesive layer? – တင်းကျပ်-Flex PCB ထုတ်လုပ်သူ recommendation
The function of the adhesive layer is to connect all the layers together. The base layer is the main layer to provide flexibility to the circuit. The significance of electrical properties is there due to this layer. Many materials are advisable to be used as a base layer but the most excellent material is polyimide. Simultaneously, this material has very unique properties that surround the area of electrical, mechanical, chemical and thermal conductivity. The thickness of the base layer ranges between 12 and 125 micrometers. Moreover, the flexibility of the circuit is directly related to the thinner layer of the circuit. The more the base layer is thinner, the more the circuit becomes flexible.
How do compression and stretching take place on a rigid-flex PCB?
When the circuit gets a bend, the outside material stretches in order to surround the radius. In this way, tension is generated. However, the inside material compresses to compensate shrinks. The region of the circuit where there is little to no tension is called the neutral-bend axis. It is the region where no compression or stretching occurs.
Generally, တင်းကျပ်-Flex PCB ထုတ်လုပ်သူ 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 တင်းကျပ်-Flex PCB ထုတ်လုပ်သူ
To become the distinguished တင်းကျပ်-Flex PCB ထုတ်လုပ်သူ 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.
အဆိုပါ တင်းကျပ်-Flex PCB ထုတ်လုပ်သူ 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.
