Some Different Types of Circuit Boards

· Uncategorized

Kinds of circuit boards include single-sided circuit boards, double-sided circuit boards, multilayer circuit boards, and flexible boards.

Printed circuit boards (PCB) are thin parts of plates which have electronic parts, and they are generally used to create electronic and communication products. There are 4 different kinds of circuit boards, each with different levels of complexity and features. Check out this article to know more about them.

Single-sided circuit boards

Single-sided circuit boards are the simplest and most common form of circuit boards. Its wiring is printed on one side, while the other part has traces and drilled holes to mount the components. The components are often mounted on the other side of the traces. There are leads that go beyond the board, so they can be soldered. Single-sided circuit boards are relatively simple to make, even at the comforts of your home. As compared to other types of circuit boards, like the double-sided or the multilayered ones, single-sided circuit boards are much cheaper. However, this type of board has a drawback. Because of its low component density, its use is only limited to simple circuits because the complex ones are very large for this board to handle.

Double-sided circuit boards

In a double-sided circuit board, the wiring patterns are on both sides of its insulating material, meaning both the solder side and the component side contain the circuit pattern. The conductor lines and also the component density of double-sided printed circuit boards are much higher as compared to single-sided circuit boards. Double-sided printed circuit boards have a design that is not only more compact, but also more complex than the single-sided ones. There are two kinds of double-sided printed circuit boards. The first one is the Double-Sided Board with Plated Trough-Hole connection (PTH). In this kind of board, its insulating substrate has circuitry on its two sides, that are attached to one another since the substrate hole of the wall is metalized. Meanwhile, the other type of double-sided circuit board is the Double-Sided Non-Plated Through-Hole connection (Non-PTH). This particular board is just an extension of the single-sided circuit board, and it also costs much lower because it doesn’t need any plating. Without the plating, contacts are designed by soldering the component leads to both sides of the circuit board. The layout design of this type of board should limit the number of solder joints, so that components can be taken away when needed.

Multilayer circuit boards

Multilayer circuit boards are made of many layers of conductors, usually between two to ten. A number of fiberglass sheets are put on top of each other to make the board. The link between the layers is made via plated-through holes. Assembling this type of circuit board requires high-precision and complexity that can only be attained with the assistance of a computer design. Just like double-sided circuit boards, multilayer circuit boards also have circuit issues related to the crossing of radio frequency signals. Nonetheless, the benefits of this board far outweigh its disadvantages.

Flexible boards

Flexible boards are plastic, heat-resistant boards which have inner conductors. A flexible printed circuit manufacturer solders the elements to these boards, that in turn, can be used for complicated technologies, such as digital cameras, televisions or dashboards of automobiles. Additionally, this type of circuit board can have just one or a number of layers.

When you have a good understanding about PCBs, you can easily fix your own appliances whenever they break down.
