Baskılı devre kartı (PCBS) are sheets made of fiberglass, composite epoxy resins or other laminated materials. PCBS can be found in a variety of electrical and electronic components (e.g., buzzers, radios, radars, computer systems, etc.). Different types of PCBS can be used depending on the application.

What are the different types of PCBS?

PCBS are usually classified by frequency, number of layers used, and substrate. Some popular types are discussed below.

L single-sided PCB

Single-sided PCB is the basic type of circuit board, consisting of only one layer of substrate or base material. The layer is covered with a thin metal, copper, which is a good conductor of electricity. These PCBS also contain a protective solder resist layer that is applied to the top of the copper layer in conjunction with a silkscreen coating. Some of the advantages that single-sided PCBS offer are:

Single-sided PCB is used for mass production and low cost.

These PCBS are used in simple circuits such as power sensors, relays, sensors and electronic toys.

L double-sided PCB

Both sides of a double-sided PCB have metal conductive layers. Holes in the circuit board allow metal parts to be connected from one side to the other. These PCBS are connected to the circuit on either side by either through-hole or surface-mount techniques. The through-hole technique involves passing the lead assembly through a pre-drilled hole in the board and then welding it to the pad on the opposite side. Surface mounting involves placing electrical components directly on the surface of a circuit board. Double-sided PCBS offer the following advantages:

Surface mounting allows more circuits to be connected to the board than through hole mounting.

These PCBS are widely used in mobile phone systems, power monitoring, test equipment, amplifiers and many other applications.

L multilayer PCB

A multilayer PCB is a printed circuit board consisting of more than two copper layers, such as 4L, 6L, 8L, etc. These PCBS extend the technology used in double-sided PCBS. The layers of the substrate and insulation separate the layers in a multi-layer PCB. PCBS are compact in size and offer weight and space advantages. Some of the advantages that multilayer PCBS offer are:

Multi-layer PCBS provide a high degree of design flexibility.

These PCBS play an important role in high-speed circuits. They provide more space for conductor patterns and power sources.

L rigid PCB

Hard PCBS are those that are made of solid material and cannot be bent. Some of the significant advantages they offer:

These PCBS are compact, ensuring that a variety of complex circuits are created around them.

Hard PCBS are easy to repair and maintain because all components are clearly marked. Moreover, signal paths are well organized.

L flexible PCB

Flexible PCB is built on flexible base materials. These PCBS are available in single-sided, double-sided and multi-layer formats. This helps reduce complexity within device components. Some of the advantages these PCBS offer are:

These PCBS help save a lot of space and reduce the overall weight of the board.

Flexible PCBS help reduce board size and are therefore ideal for a variety of applications requiring high signal routing density.

These PCBS are designed for operating conditions in which temperature and density are considered.

L Rigid – flexible -PCB

Rigid flexible – A PCB is a combination of rigid and flexible circuit boards. They consist of multiple layers of flexible circuits connected to more than one rigid plate.

These PCBS are precisely constructed. As a result, it is used in a variety of medical and military applications.

These PCBS are lightweight, saving up to 60% of weight and space.

L high-frequency PCB

Hf PCBS are used in the frequency range of 500MHz to 2GHz. These PCBS can be used in a variety of critical frequency applications, such as communications systems, microwave PCBS, microstrip PCBS, etc.

L Aluminum backplane PCB

These plates are used for high-power applications because the aluminum structure helps to dissipate heat. Aluminum-backed PCBS are known to have high levels of rigidity and low levels of thermal expansibility, making them ideal for applications with high mechanical tolerances. PCB is used for LED and power supply.

Demand for PCBS is catching up across industries. Today, you will find a variety of well-known PCB manufacturers and distributors that can meet the needs of the competitive connected equipment market. It is always recommended to purchase PCBS for industrial and commercial use from reputable manufacturers and suppliers.
