PCB 101: Different Types of Printed Circuit Boards

Posted on Sept. 18, 2018

Printed circuit board construction can be carried out in three fundamental ways namely multi-layered, double sided and single side techniques. Consequently, the following are some of the different types of Printed circuit Boards.

Single Sided Printed Circuit Boards

The printed circuit boards that are single sided contain a single base substrate or material layer. Generally, the substrate's one side is covered with a metal layer that is made of copper and is often thin. The use of copper metal is mainly because of its excellent electrical conductivity. The printed circuit board contains different electric elements and circuits on the one flank. Importantly, such a module is useful for electronics that are easy. Also, learners usually begin by first fabricating and shaping this single-sided printed circuit boards. Equally, these printed circuit boards are cheaper when used for mass production.

Double-sided Printed Circuit Boards

This PCBs is a more common printed circuit board compared to the single sided ones. This particular one has all its sides of the substrate boards made of layers of conductive metals. Equally, the elements are attached to the two edges. The double-sided printed circuit boards use surface mount and through-hole technology to join the circuits. The latter utilizes feeding wires that are small to solder all ends to the appropriate elements. However, the printed circuit boards that exploit the surface mount technique are utterly distinctive from the through-hole as it does not use wires. Instead, it uses several small leads to straight solder through the board.

Multilayer Printed Circuit Boards

This kind of Printed Circuit boards expands the complexity and density of the various designs of printed circuit boards by accumulating additional coatings outside the bottom and top covers that are observed in double-sided configurations. Power planes are the main supplementary coatings that are utilized for this printed circuit boards design. The power planes lower the electromagnetic interference levels from the emissions of the model, and they supply power to the circuits.

Rigid Printed Circuit Boards

This printed circuit board contains various sides and multiple numbers of coats. They can also exist in shifting rigidities. Most users of this printed circuit board prefer it in situations when they duplicate a circuit board. Equally, rigid PCBs utilize the materials containing rigid substrates, such as fiberglass residues from the twisting of the board. An example of a rigid printed circuit board is the computer motherboard.

Flexible Printed Circuit Boards

These printed circuit boards contain flexible plastic substrates that allow the printed circuit board to mount into various arrangements that the inflexible ones cannot fit. They also enable easy shifting without destroying the circuits during use on the printed circuit board. Additionally, the flexible printed circuit boards can restore bulky or heavy cabling in more exceptional gears such as satellites that are impacted by space and weight.

Rigid-Flex Printed circuit Boards

These boards combine technologies from both the rigid and flexible circuit boards. Usually, they contain circuit boards that are rigid, and they join the flex circuit boards. Importantly, if there are request demands, then this printed circuit boards can be more involved.
