Multilayers Rigid, Flex, Rigid-flexible Circuit Board

Printed circuit boards can be classified into four main types: rigid, flexible, semi-flexible, and rigid-flexible. The key factor determining the type of PCB is the substrate material used. Among these types, rigid boards are the most common and straightforward to manufacture with multiple layers. When a rigid board consists of four or more conductive layers, it is referred to as a multilayer rigid PCB. These layers are separated by an insulating material, forming a single integrated unit.

Multilayer Rigid PCBs

Three main types of vias are used to establish connections between the layers in a multilayer rigid PCB: buried vias, blind vias, and through-hole vias. This structure typically consists of external layers located at the top and bottom, which function as single-sided boards. The internal layers, on the other hand, act as double-sided boards and are interconnected. Some of these layers may serve specific purposes such as power planes or ground planes. Depending on the requirements of industrial projects and design specifications, rigid multilayer PCBs can have many layers, ranging from a few to over a hundred. However, it is more common to find multilayer PCBs with four to eight layers in various devices, such as smartphones, where the circuitry is often configured on 12-layer boards. In these applications, the inner core of multilayer rigid printed circuit boards comprises the core layer, prepreg, intermediate layer, and inner layer.

Flex Circuit Board

Flexible PCB is a kind of flexible circuit board with the simplest structure, not only can be used alone but also can be connected to other circuit boards, used in communications, security, medical, industrial control, home appliances, and digital products, etc. Flexible PCB are generally divided into single-layer boards, double-layer boards, multi-layer boards. Flex PCB have numerous advantages over rigid boards, including space-saving, lightweight construction, excellent signal integrity, and the ability to conform to non-planar surfaces. They are commonly used in industries such as consumer electronics, automotive, medical devices, aerospace, and more.We aim to deliver high-quality Flex PCB that meet industry standards and customer specifications. Their services may include prototype development, volume production, component assembly, and quality assurance.

Rigid-flexible Circuit Board

The birth and development of FPC and PCB has given birth to the new product of Rigid-Flex PCB.The Rigid-Flex PCB is rigid pcb and flexible pcb,through pressing and other processes, according to the relevant technological requirements combined together,formed with FPC characteristics and PCB characteristics of the circuit board.

The characteristics of Rigid-Flex PCB determine its application field covers all application fields of FPC and PCB, such as communication, smart home, optoelectronics, industrial control, medical equipment, automotive and consumer electronics.
