Diferencia entre PCB de una cara, PCB de doble y multicapa27 de julio de 2020
PCB de una cara frente a PCB de doble cara frente a PCB de múltiples capas
Las placas de circuito impreso son una parte importante de la electrónica moderna. Lo bueno de que están disponibles en una amplia gama de tipos y subcategorías. Por ejemplo, el más simple de todos es el PCB de una cara, luego tiene un tablero de circuito impreso de doble cara o el PCB multicapa.
All these PCB types serve the basic purpose; however, they differ in terms of performance efficiency and density. Likewise, every PCB comes with different uses and price points. If you are planning to purchase a PCB for your equipment, you need to have an understanding of the basic three types.
Learn about their difference and how can they make an impact. In this blog post, we are going to talk about the basic three types of Printed Circuit Boards, their differences, advantages, and usage.
Single-Sided PCB Vs other Types of PCB
PCB de una cara
Single-layer Printed Circuit Board, often known as the Single-Sided PCB is a Printed Circuit Board that consists of only one layer. The layer is made up of conducting material and is located on one side of the Printed Circuit Board.
On the other side of the board, the manufacturer accommodates different electronic components. Single-sided Printed Circuit Boards are highly cost-effective, especially when you do mass production. They are perfect for a wide variety of electronics.
However, clients often use Single-layer PCB when they are having a tight budget. In addition, the electronics do not require high-density board for smooth and seamless functionality.
Materials used for Single-Sided Board
There are several materials that manufacturers tend to use for Single layer PCB. For instance, they can use reinforced phenolic resin along with a copper foil. Or there is always the possibility of using Glass fiber reinforced epoxy resin along with copper foil, among many others.
Since the design and making of Single-layer placa de circuito impreso is not complicated at all. Therefore, they are among the most common PCBs to the manufacturer and fabricate. The main purpose of Single-layer PCB is the same as that of its counterparts.
However, its fast manufacturing ability and cost-effective production make it popular among several day to day electronics. Some of them, we have listed below.
- Solid State Drivers
- Fuentes de alimentación
- Audio Equipment
- Camera System, among others.
Advantages of Single-Sided Printed Boards
Manufacturing Cost for Single-Sided PCB is highly cost-efficient because of its basic and simple design. Also, their lack of complexity makes them easy to understand for a variety of manufacturers, thus you can find several reliable manufacturers.
The lack of complexity reduces the error of chances at different manufacturing stages.
The higher the number of PCB units, the lesser the price.
Double-Sided Printed Circuit Boards
Single-sided PCB and Double-Sided PCB are similar, with just one major difference. Double-sided Printed Boards have two-sided traces instead of a single-sided board. There is a top and a bottom layer for a Printed Circuit Board.
With Double-Sided PCB, manufacturers have the facility of mounting components and conductive copper on both sides of the Printed Board instead of one, as was the case in a single-layer Printed Board. This means that manufacturers are able to achieve higher density without actually requiring a point to point soldering.
Nonetheless, the fabrication process of the double-sided Printed Board is more complex in comparison to the single-sided PCB. Despite the manufacturing complexity and increase in the price, we suggest using double-sided PCB for all the benefits it offers.
Material Used for Double-Sided PCB
Like Single-Sided PCB, Double-Sided Printed Circuit boards also come with a woven glass epoxy base. However, with Double-Sided PCB, you have a copper coating on both sides of the Printed Circuit Board. Also, it is possible to use varying copper thickness.
The thickness greatly depends upon the requirement of the intended equipment. Since they offer complexity without overburdening in terms of prices, therefore, they are becoming increasingly common.
A lot of applications incorporate Double-Sided PCB, we have listed some of them below.
- Sistemas telefónicos
- Industrial Control
- Car Dashboards
- Máquinas expendedoras
- LED Lighting systems
Advantages of Double-Sided Printed Circuit Board
Double-sided boards have an extra layer on which manufacturers add components. Thus, an increase in the circuit density. With extra space, it is possible to mount more connectors and components.
These boards offer more complexity; therefore, they are perfect for modern electronics that require demanding Printed Circuit Boards.
With two sided-PCB, you tend to place components on both sides of the board. Thus, reducing space while increasing efficiency.
Multilayer Printed Circuit Boards
If you require extremely high-level circuit complexity, multilayer PCBs are the best option. They consist of more than three copper layers that are laminated together. Multi-layer Printed Boards are becoming imperative especially for electronics that require a high level of complexity.
Something which is not manageable with single-sided PCB or double-sided Printed Board.
Materials Used for Multi-Layer PCBs
The basic core materials for Multi-layer Printed Boards are the same as that of single and double-layered PCBs. However, there is a difference in the manufacturing process. After etching the initial core, they then have to prepreg it with an additional layer of soft fiberglass.
This helps is keeping the layers intact. This turns into the hard fiberglass once the board sent through the hot press. Thus, ensuring robustness and toughness of the PCB after the curing process. In the case of a 4-layer PCB, there will be 1 core, prepreg, and a copper foil layer on both the bottom as well as the top of the Printed Circuit Board.
A number of complex technologies greatly depend upon multi-layer Printed Boards for effective functionality and long-lasting performance. Below are some of these technologies.
- Atomic Accelerators
- Heart Monitors
- Space Equipment
- Scientific Equipment
- GPS systems
When it comes to fabricating your own placa de circuito impreso, it is important to understand the difference between the 3 basic types of Printed Boards. You also need to focus on your application requirement to choose the right PCB.
