A small plate is used in absolutely all areas where electronic devices are required and is part of military equipment, computers and mobile phones, cars and much more.

Electronic devices made a huge step forward after the invention of PCBs a hundred years ago.

At the moment, one of the most reliable PCB manufacturers in Russia is Saifon Technologies.

PCBs for manufacturing of electronic devices

PCBs are designed to ensure that individual electronic components have an electrical connection to each other, while being isolated from each other to avoid short circuits and for proper current transmission.

What is a PCB?

All electronic individual parts are attached to the PCB substrate with the electronic circuit applied. It has the form of a pattern of thin lines and consists of printed conductors. Each output of elements is attached to such a "painted" base by soldering. In addition to the circuit pattern, the base also has mounting and metallized holes, contact pads and others.

This is enough to call the board a printed circuit board. But any modern PCB has protection in the form of a solder mask, which properly isolates all electronic elements and protects the PCB from physical impact. The mask is usually painted green, which is why it is popularly called "zelenka".

There are many types and subtypes of PCBs. The main types are distinguished by the number of layers with a printed pattern:

Which PCBs are used in electronic devices?

— Single-layer PCBs. A layer with conductors is applied to one side of the substrate. Single-layer PCBs are the cheapest and most affordable option. But at the same time, they are the oldest. They are often found in simple household appliances such as remote control for TV.

— Double-layer PCBs. A coating with conductors is applied to both sides of the substrate layer. They have a higher packing density and reliability in comparison with single-layer PCBs. In the Russian market, the share of double layer PCBs ranges from sixty-five to seventy-five percent. Double-layer PCBs are widely used in radio electronics, telecommunications, alarm systems and tracking devices, in modern household appliances, etc.

— Multilayer PCBs. Each layer is a full–fledged insulating plate, all layers are combined in a single electrical circuit using metallized holes. Each layer has printed conductors and a circuit pattern.

Such a multilayer system can be achieved either by gluing two-layer PCBs, or by using a layer-by-layer build-up. With the build-up method, the PCB usually has no more than five layers, but as the technology develops, they can become many times more. Such PCBs are of the highest quality and have very good technical characteristics, stability and other things. But they are also much more expensive.

Depending on the substrate material, PCBs have different plasticity. If the PCB is made of getinax, fiberglass and other dielectrics, the substrate will be rigid. Polyamide or dacron materials of kapton type result in a flexible substrate.

Depending on the substrate material

Saifon Technologies is a reliable supplier that can manufacture PCBs of the required configuration for use in various fields, from household appliances to the military and space industries.

— Rigid PCBs were very common earlier, since the strong substrate has a high resistance and is not subject to twisting. A simple example of use is the motherboard of any PC.

— Flexible PCBs. One of the undeniable advantages is the substrate flexibility, which is why it can be bent around electronic devices if necessary. Besides, such PCBs cost less and have much smaller size and weight. They are convenient to mount and they are great for three-dimensional installation.

— Flexible-rigid PCBs. The most complicated option, since it is a complex combination of flexible and rigid PCBs. They have many modifications for different types of devices. In flexible-rigid high-quality PCBs, it is important to choose a good supplier, since such PCBs have a high cost and the quality of the entire electronic device directly depends on them.
