1. The main PCB board is a flat plate that provides mechanical support for electronic components.
2. In addition, the board uses conductive pads to accept the terminals of the components.
3. The main PCB board connects the terminals of the components using a plane and a cable.
The role of the main PCB board in a electronic device is crucial, as it not only provides physical support for the components, but also facilitates the conduction of electrical signals between them. It is important to ensure that the board is manufactured with high quality materials and precise engineering, as any flaws in the board can result in malfunction or failure of the entire device. Additionally, proper insulation and protection measures should be in place to prevent short circuits and other electrical issues. As PCB experts, it is our responsibility to ensure that the main PCB board meets all necessary standards and specifications for optimal performance and reliability.
The Functions and Manufacturing Process of the Main PCB Board
1. The main PCB board has two primary functions. Firstly, it is responsible for the installation of electronic components at specific locations on the outer layer. Secondly, it provides electrical connections between component terminals. At the same time, the main PCB serves as a platform for the careful installation of electronic components within it.
2. The main PCB board is the building block for most electronic devices and can be single-sided, double-sided, or multi-layer. It is a flat insulating material with copper foil laminated on the substrate, connecting electronic circuits. Electroplated copper conductors, known as vias, pass through holes on the board.
3. Multi-layer main PCB boards can have multiple layers of copper, providing better signal integrity and more routing options. However, their manufacturing cost is high and time-consuming. Double-layer PCBs are easier to manufacture, as both sides are made of copper. The complexity of a single board depends on the number of layers and the degree of interconnection between layers.
Materials Used for Main PCBs
1) Substrate
The main PCB board can use flexible or rigid substrates, depending on the application. Rigid main PCBs use polyimide or FR4, while flexible main PCBs use high-temperature polyimide film.
2) Copper Layer
The copper layer is applied to one or both sides of the PCB and provides electrical signals between components on the circuit board.
3) Solder Mask
Solder mask is a protective material made of polymers that protects PCBs and acts as the PCB skin.
4) Silkscreen
Also known as the nomenclature, silkscreen is laminated on the component side of the main PCB board and helps to represent logos, settings, and symbol switches.
The Manufacturing Process of the Main PCB Board
1) Develop circuit images using photographic tools or direct imaging.
2) Remove excess copper from the inner layer to reveal mats and traces.
3) Develop PCB stacking by laminating PCB materials through pressure and heating, with the help of prepreg for the bonding process.
4) Drill and install holes, which assist in the placement of components through PTH technology.
5) Apply a solder mask using ultraviolet radiation to the entire surface of the board to weld the metal pad.
6) Add surface finish to the board, selecting the appropriate surface finish for the specific PCB.
7) Check and test the circuit board for defects or errors to ensure its functionality.
The main PCB board is a core component of electronic devices and is essential for their function. It is widely used in different applications and industries, making it a crucial element in the production of electronic products.
