What comes into your mind when you hear the term embedded? It simply means that a particular item is placed inside the main product. It is the same with PCBs or printed circuit boards. You see, PCBs are basically a part of almost every single electronic device that you can think of.
In fact, almost everything that you can think of from your computer to your TV is powered by a PCB. Now, the question is why? Why do we need these things in our everyday life?
An embedded PCB works with other smaller components to create a final product. An embedded PCB is generally flat, which makes it easier to embed in another object.
Similar to how a smaller computer server can be inserted into an office building, so too can an embedded PCB be inserted into something like a car or refrigerator.
The embedded PCB has many benefits over traditional PCBs that we see as stand-alone objects because of its compact size and ability to be used with other smaller components. Here is everything you need to know about this technology:
What is an embedded PCB?
An embedded PCB is a mini PCB that is embedded inside another device. It can be placed inside a car, refrigerator, computer, or other appliances. The embedded PCB is commonly used for automation and control purposes.
Why use an Embedded PCB?
The main reason to use an embedded PCB is cost savings. A circuit board can cost thousands of dollars to make, so by embedding a PCB into a device, you are saving money that would have otherwise gone towards purchasing a circuit board.
The embedded PCB is smaller than a normal PCB, which makes it easier to embed. Since it is smaller, it also takes less time to produce, helping cut down on costs as well.
The embedded PCB also makes the device easier to use, which could result in higher sales for the device. Using an embedded PCB could also reduce the overall time it takes to produce the final product when compared with a normal PCB.
What does an embedded PCB look like?
Embedded PCBs are smaller than normal PCBs, which makes it easier to embed in another object. An embedded PCB is generally flat and has many benefits over a regular PCB because of its smaller size and ability to be used with other smaller components.
A PCB is a board that is composed of many layers. It contains copper patterns that act as conductors, as well as a substrate material such as fiberglass or FR-4.
The copper layers are what give the PCB its ability to act as a conductor, which is how it is able to transmit electricity. The substrate material provides support and acts as the base of the PCB. It is what gives the PCB its shape and enables it to be connected with other PCBs.
In terms of color, a PCB can be almost any color, but most are either green or black.
What is the difference between a PCB and an embedded PCB?
A regular PCB is a board that is made of many layers of copper and fiberglass, which are then covered with a protective layer. It is not meant to be embedded into another object, but instead, it is used on its own.
An embedded PCB is smaller than a regular PCB, making it easier to embed in another object. They are also thinner than normal PCBs and can be connected with other components that are smaller than the overall size of the embedded PCB itself.
Another major difference between these two is the layer count. An embedded PCB has less than 10 layers, whereas a regular PCB has more than 10 layers.
The design features of embedded PCB
The design features of an embedded PCB simply describe the physical outlook of the board. It determines how the PCB will fit into the device in which it will be installed.
It is important to carefully consider the design when buying embedded PCBs. This is because the design features are the main determinants of how the PCB will look in your device.
The following are important design features of an embedded PCB:
-PCB shape and layout: This is the shape of the PCB and the arrangement of components on it. This can determine how easily you can fit it into your device.
-Size: The size of the board determines where you can fit it in your device. This is because the size will determine what other components in your device will be affected by its presence.
-Layer Count: The layer count is a major design feature, as it determines how many layers will be present on the board itself. An embedded PCB has fewer layers than a regular one, meaning that it is smaller and thinner than a regular PCB.
-Number of Components: The number of components on the board is an important feature. This is because it determines the complexity of the PCB and how difficult it will be to install.
-Component Placement: This describes how the different components are placed on the PCB. It can determine how easily you can fit them into your device, as well as their ease of installation.
-PCB Edge Finishing: The edge finishing describes how smooth or rough the edges are on a PCB. This is an important factor because it determines whether or not you will be able to effectively install it into your device without damaging any other components in your device.
What determines the size of embedded PCB?
At this point, you should know that not all PCBs have the same size. They come in different sizes since they are designed for different devices. or example, a PCB for a smartwatch will be different from that of a smart car.
As a rule of thumb, the size of the PCB is determined by the size of the device or product it is going to be installed in. There are also some factors that can determine how big or small your embedded PCB should be. These include:
-The Number of Inputs and Outputs: The number of inputs and outputs on your PCB will determine how big it should be. This is because it determines how many wires you will need to connect all the components together. The more wires you need, the bigger and bulkier the board will become.
-The Number of Integrated Circuits: The number of integrated circuits on your board and their sizes also determine its size. For example, if you have a lot of tiny ICs like sensors for temperature control, your PCB has to be larger than one with only one large IC. This is because in order to fit them all into your board you need more space for them. Also, if they are larger ICs then they require more space since they occupy more area on your board when compared with smaller ones.
-The Number of External Connections: The number of external connections on your PCB will determine how big the board should be. This is because more external connections mean more wires required to connect to them.
-The Frequency of Your Circuit: The frequency of your circuit determines the speed at which it operates and the amount of power it consumes. If your circuit operates at higher frequency, then you will need a bigger PCB to accommodate it. Similarly, if you are using a high frequency then you will need a larger PCB for it as well.
-The Type of Device: The type of device that you are designing determines how big your PCB should be. For example, if you are designing a small-scale device like an alarm clock then a small-sized PCB is required because there is no need for large space or high power consumption. However, if you are developing something like an embedded system or even an application in which high-level functions need to be performed by hardware components like intelligence, then the size and complexity increase significantly as compared to other devices and thus require larger PCBs as well.
Embedded PCB assembly and placement process
The placement process of the embedded PCB entails the following steps:
- Designing the PCB: This involves designing the PCB and its components. The design of the PCB determines how much space it will take up in your device and how much power will be consumed. This step also involves selecting the material that you want to use for the board as well as selecting a board size that is suitable for your device.
- Fabrication: The fabrication process of the embedded PCB entails cutting out a piece of copper clad board from a copper sheet using a cutting machine, drilling holes for all its components and connecting them through wires to each other using soldering iron. If you are using a printed circuit board then it must be etched in order to have an accurate pattern printed on it or printed through silk screen printing method, whereas if you are using an assembled PCB then it is only required to be drilled for wiring purposes. The process of drilling holes and soldering them together is called SMT (Surface Mount Technology). This step also involves adding components such as resistors, capacitors, transistors and diodes at specific locations on the PCB which are connected to each other by wires.
- Testing: Once all these steps are complete, they must be tested thoroughly before they can be used in your device and if any errors occur during this testing then they can be fixed before going further with designing or fabrication processes.
