PCB fundamental: aspects and design

What is PCB

PCB are the backbone of modern electronics. They are used to connect electronic components and provide a platform for mounting them. PCB come in a variety of sizes and shapes, but most are rectangular.PCB are made from a variety ofmaterials, but the most common is FR-4,a type of fiberglass. The copper tracks on the PCB circuit board are etched to form the desired circuit.

The tracks are then covered with a thin layer of solder mask, which protects the copper from oxidation and Short for printed circuit board, a PCB is a board made of insulating material upon which conductive pathways are printed or etched. These conductive pathways connect different components on the board, such as microprocessors, capacitors, and resistors.PCB are found in a variety of electronics, from ultraviolet sterilizing lamp and power meter to laser tape and wall detector.

They are also used in more industrial applications, such as control systems for factory machinery. PCB can be simple, with only a few components, or complex, with many layers and a variety of components. The size of a PCB also varies, from large boards used in computers to tiny boards found in Watches.

What is the function of PCB

As an important component in many electronic devices, the function of a PCB is to mechanically support and electrically connect electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. By doing so, it allows signals and power to be routed between physical devices. In most cases, they can be found in electronic equipment and are typically readily recognized as the green-colored board.

What are the parts of PCB

PCB parts

The electronic parts found in these boards are transistors, fuses, resistors, and capacitors. All of these components contribute to the smooth functioning of the device; if one of them fails, the whole PCB shuts down, affecting the functionality of the gadget as a whole.When it comes to printed circuit board, there are a variety of different electronic parts that can be found within them. These components include transistors, fuses, resistors, and capacitors.

All of these parts play a role in ensuring that the PCB functions correctly – if one component fails, it can cause the entire board to fail, which can then impact the performance of the device as a whole. As such, it’s important to understand the role that each component plays in order to ensure that your PCB is functioning properly. Let’s take a closer look at each one:

Transistors: Transistors are one of the most common types of electronic components found in PCB. They act as switches, allowing electrical current to flow through them in order to power the device on or off.

Fuses: Fuses are designed to protect the PCB circuit board from damage by breaking the circuit if there is an overload of current. This helps to prevent any further damage from occurring.

Resistors: Resistors help to control the flow of electricity by regulating the amount of current that flows through them. This ensures that the device doesn’t receive too much or too little power, which could cause it to malfunction.

Capacitors: Capacitors store electrical energy and then release it when needed. This helps to even out any spikes in voltage, which can again help to prevent damage to the PCB.
These are just some of the electronic components that can be found in a PCB. understanding the role that each one plays is essential for ensuring that your PCB is functioning correctly.

How many kinds of materials are needed to build a PCB board

A Printed Circuit Board is made up of several different materials, the most common being FR-4. Other materials used in PCB fabrication include PTFE and metals. Each material has its own unique properties that make it suitable forspecific applications. For example, FR-4 is widely used because it is strong and durable, while PTFE is used for high-speed and high-frequency applications.

Introduce the production process of PCB board

To make a PCB, there are many different steps that are required in order to produce a quality product. The process can be broadly split into four main sections: material preparation, circuit board fabrication, component assembly, and testing & inspection.

1)Material Preparation: In this stage, the necessary materials are gathered and prepared for use. This includes everything from the substrate material to the solder mask and silkscreen.

2)From File to Film PCB printing: When designers generate the PCB Board schematic files and manufacturers execute a DFM review. Manufacturers utilize a special printer called a plotter, which creates photo films of the PCB, tomanufacture circuit boards.

3)Circuit Board Fabrication: This is the actual process of creating the circuit board itself. It involves etching away unwanted copper, applying the solder mask, and applying the silkscreen.

4)Component Assembly: In this stage, all the components are placed on the circuit board and soldered in place. This includes everything from the ICs to the capacitors and resistors.

5)Testing & Inspection: Once all the components are in place, the circuit board is given a final test to ensure that it is functioning correctly. Any defects that are found are then corrected before the board is shipped out.These are the basic steps that are involved in the PCB manufacturing process. Depending on the type of board being made, there may be additional steps that are required. For example, multilayer boards require a different process for creating the inner layers.

However,these four steps form the foundation of circuit board production.

Note:
Blind Vias: When the holes link one layer to the outside surface, they are known as blind vias.

Buried Vias: Holes that connect internal layers but not the outside surface.

What equipment is needed in the production process

In the production process of PCB, various equipment is needed for different purposes. The most important factor that affects the product quality of PCB is the raw material. Other factors such as equipment and processes also play an important role in determining the quality of PCB products.

The equipment used in the production process of PCB circuit board are:

1. Drilling machine: It is used to drill holes on the PCB board. The size and position of the holes are very important for the final product.

2. Router: It is used to cut the PCB board into different shapes.

3. Etching machine: It is used to etch the copper traces on the PCB board.

Etching machine
4. Masking machine: It is used to apply the solder mask on the PCB board.

5. Silkscreen machine: It is used to print the legends and other information on the PCB board.

6. Soldering machine: It is used to solder the components on the PCB board.

How does it affect product quality

With the development of technology, circuit equipment is getting faster and more efficient, and equipment is becoming increasingly sophisticated. The price is getting more and more expensive. Because of this, little electronic circuit board producers are unable to increase more costly production equipment, resulting in a rise in demand for labor. To prevent the company from becoming unprofitable, you’ll need to hire more workers.

How to evaluate the quality of PCB

There are many factors to consider when assessing the quality of a PCB. The following factors are some of the most important:
1. The number of layers: More layers generally mean better quality, as it allows for more routing options and greater flexibility.
2. The thickness of the copper: Thickness is important as it determines the amount of current that can be carried by the PCB.
3. The quality of the solder mask: The solder mask is a thin layer that covers the PCB and protects it from shorts and other damage. A good quality solder mask will be smooth and even, with no bubbles or defects.
4. The quality of the silkscreen: The silkscreen is the printed legend on the PCB board that indicates component placement and other important information. A good quality silkscreen will be clear and legible, with no smudging or fading.
5. The overall finish: The PCB should have a smooth, even finish with no rough edges or visible defects.
If you are unsure about the quality of a PCB, it is always best to consult with a professional manufacturer or service provider. They will be able to assess the board and provide you with a detailed report outlining any potential issues.

What are the key factors that will affect the quality of PCB during the production

The following are some factors to avoid internal lining separation: Any defect in the regulation of production methods in through-hole fabrication can result in flaws. And if greater than 2 mil, copper wicking happens when copper travels across the glass fibre fabric from a plated-through hole (PTH).But when the inner layer copper pad (measured from the hole wall plating to its outermost length) is less than 2.0 mil, Internal annular ring happens

How to choose the right PCB manufacturer? What to look out for
