Six Kinds of Printed Circuit Boards you Should Know


Electronic devices have printed circuit boards (PCB) to make them work. PCBs in computers, phones, and other devices have different PCBs. Printed circuit boards can look all the same; however, there are actually various kinds of PCBs. These include the following:

Flexible Single Sided

This kind of printed board circuits is less complex and more affordable to assemble than other kinds. They have a conductor that is layered on top of a flexible dielectric film. When it comes to this kind of PCB, you can choose either a coverlay or a semi-flexible liquid photo imagable (LPI) solder resist. Assemblers use more stiffeners to make some part of these PCBs a bit rigid.

Flexible Double Sided

The PCB assembly includes the use of a couple of copper layers with both layers having a dielectric layer in between. This type of PCB provides you with the option of a semi-flexible LPI solder resist or a coverlay. But, it is often connected with plated using holes. This PCB may have parts made more rigid.

Rigid Single Side

These PCBs are used in devices that require a low level of complexity. They are easy and simple to assemble because they just have one layer of copper on a rigid base material. The making of these PCBs can include adding idents and solder resists, depending on the application’s requirement.

Rigid Double Sided

This kind of PCB is the most commonly used because each side is used for attaching parts and components. Unlike their one-sided counterpart, these circuit boards have two copper layers on a rigid base material. But, the copper layer’s sides are not connected. Assemblers can add idents and solder dents afterward. These PCBs can be used with both surface mount components and holes.

Flexible Multilayer

These printed circuit boards have at least three copper layers, which also have a dielectric layer between them. In general, they are connected through plated holes. Much like their rigid counterparts, they retain the semi-flexible LPI solder resist or a coverlay option. A number of their parts can feature more rigidity with stiffeners.


The assembly of this kind of circuit boards includes the permanent combination of a part of the flexible and rigid board together. These PCBs are used for conditions with limited space.

These days, the PBC industry has evolved. The majority of new PCBs have more features to ensure that electronic gadgets function better. Makers of PCBs provide plates that have high-aspect ratio holes. The function of PCBs includes frequency and signal and high-aspect ratio holes make a uniform electrolyte flow to various panel destinations.

Moreover, PCB Assembly services include the use of high-frequency materials meant to mitigate signal loss when PCBs are in use. Picking the most suitable material for a circuit board will identify an electronic device’s quality. For devices which rely on frequency, the use of the right material will cause a significant improvement in their functionality. Those who are looking for quality circuit boards and materials should get in touch with a reputable manufacturer.
