Как производители жестких гибких печатных плат повышают производительность печатных плат?

Как работают различные компоненты жестко-гибкой печатной платы?

 

Это эпоха четвертой промышленной революции. Если мы хотим идти в ногу с требованиями времени, мы должны признать важность технологий в нашей жизни. Как правило, эта статья расскажет вам об одном из этих технических инструментов, с помощью которых основные системы отрасли ищут надежный прогресс и развитие. Я собираюсь изучить информацию о Rigid-Flex PCB . Стоит отметить, что первый компьютер в мире использовал технологию Rigid-Flex PCB. В современную эпоху вычислительные устройства, медицинское оборудование, космические аппараты, текстильные технологии - вот лишь несколько примеров, в которых технология Rigid-Flex используется в коммерческих целях.

Что такое Rigid-Flex PCB?

Rigid-Flex PCB - это печатная плата, которая представляет собой гибрид жесткой и гибкой подложек схемы. Эта печатная плата имеет качества и характеристики, которые превосходят традиционные печатные платы. Следовательно, наиболее важным преимуществом этой печатной платы является то, что на ней не используются кабели и разъемы. Однако он может электрически соединять цепи.

Как производители жестко-гибких печатных плат улучшают производительность?

• Потеря сигналов больше не проблема. Улучшает качество передачи сигнала.
• Печатные платы Rigid-Flex способны обеспечить следующие преимущества:
• Теперь импеданс находится под контролем.
• Многие проблемы с подключением исчезают.
• Благодаря электрическому подключению вес системы становится настолько небольшим.
• Многие другие компоненты находят место для крепления.

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

Rigid-Flex 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? – rigid-flex PCB manufacturers 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, rigid-flex PCB manufacturers 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 rigid-flex PCB manufacturers

To become the distinguished rigid-flex PCB manufacturers 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.

Процесс rigid-flex PCB manufacturers 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 rigid-flex PCB manufacturers 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.
