I-tech also provides Rigid pcb manufacturing which including FR4, Ceramic/Rogers, Metal/Aluminum/Copper material etc.

A rigid printed circuit board, characterized by its non - foldable and non - twistable nature, offers structural integrity that sets it apart from other types of printed circuit boards. Crafted from a sturdy substrate, this rigidity provides the necessary strength for various applications. Once fabricated, its design remains fixed, with little room for modification.

The composition of rigid PCBs typically consists of a solid substrate, copper traces for electrical conduction, a protective solder mask, and a silkscreen layer for component identification and markings. These layers are bonded together using heat and adhesives, resulting in either single - sided or double - sided configurations. Moreover, they can be further categorized as single - layer or multi - layer boards, depending on the complexity of the circuitry.

In the realm of computers, numerous rigid PCBs are at work, but the motherboard stands out as the most prevalent. Serving as the nerve center of the computer, it acts as a communication hub, enabling seamless interaction among the different components. It efficiently distributes critical data to essential elements such as the GPU (Graphics Processing Unit), RAM (Random - Access Memory), and CPU (Central Processing Unit).

In contrast to flexible PCBs, rigid PCBs are designed to fit into specific, pre - defined areas within a computer. Their fixed shape remains unchanged throughout the lifespan of the machine. Whether it's a single - layer, double - layer, or multi - layer board, rigid PCBs all fall within a common range of typical applications, fulfilling crucial functions in the electronic ecosystem.

                    Difference Between Rigid and Flex PCB

Both rigid and flex printed circuit boards are widely used in the electronics industry. However, they exhibit substantial disparities in terms of their design characteristics and practical applications.

As the name indicates, a rigid printed circuit board is a stiff and unyielding board. It retains its shape consistently throughout its entire lifespan. Once the manufacturing process of a rigid board is complete, any modification to its form becomes extremely challenging, if not impossible.

Conversely, flex printed circuit boards are highly flexible. They can be bent and contorted as needed to fit into various spaces and configurations. This inherent flexibility allows flex PCBs to occupy significantly less space compared to their rigid counterparts. Notably, in contrast to rigid PCBs, which can be single - sided, double - sided, or multi - layered, flex boards are predominantly single - sided.

The manufacturing process of flex PCBs is more intricate and costly than that of rigid boards. This higher cost often renders them less appealing for use in certain devices where cost - effectiveness is a crucial factor. Despite this economic drawback, flex PCBs possess several distinct advantages that rigid boards lack. Their flexibility not only enables them to be shaped according to specific requirements but also facilitates more efficient and reliable connections between different circuit boards, electronic components, and user interfaces. Moreover, flex PCBs are lighter in weight, demonstrate superior vibration - absorption capabilities, and are far more resistant to warping due to their pliable nature.

Rigid PCB application

There are several typical applications as rigid printed circuit boards are among the most common boards found in electronic devices. These include:

• Use as motherboards for desktop and laptop computers

• File servers and storage devices

• Found in cell phones and other portable devices

• Used in medical equipment such as CT scans, x-rays, and pacemakers

• Found in automobiles

• Used as signal repeaters and GPS for mobile phones and other devices

Single/Double-sided PCB

The type has 1 or 2 layers of copper pathways. The dielectrics are sandwiched in the middle and work well in high and low-temperature environments.

Multilayer PCB

The multilayer board has  2more  layers of conductive copper, such as 4, 6, 8... and so on.Equal dielectric layers separate each.
