Customized PCB circuit boards, you must know these precautions!

Today, the one-stop PCBA intelligent manufacturing manufacturer will tell you what is a PCB circuit board? The types of PCB and the precautions for customizing PCB circuit boards. In modern electronic devices, printed circuit boards (PCBs) are one of the most important components. As the "home" of electronic components, PCBs not only carry the connection of circuits, but also directly affect the performance and reliability of equipment. If you are planning to customize PCB circuit boards, understanding the following common questions will pave the way for the success of your project.

1. What is a PCB circuit board?

PCB is a substrate with an insulating material substrate and a conductive pattern (usually copper foil) on the surface, which is used for electrical connections between electronic components. It forms a conductive path by etching or printing to achieve efficient transmission of electronic signals.

2. Types of PCB

1. Single-sided board

Single-sided board has conductive lines on only one side, with a simple structure and low cost, suitable for basic circuits.

2. Double-sided board

Double-sided board has conductive layers on both sides, and the connection of the two-sided lines is achieved through vias, which is suitable for more complex circuit designs.

3. Multilayer board

Multilayer board has more than two conductive layers separated by insulating materials between the layers, which is suitable for high-density and high-performance circuit requirements.

4. Flexible board (FPC)

Flexible board is made of flexible substrate, which can be bent and folded, and is suitable for equipment with limited space or frequent movement.

III. Preparation before designing PCB

1. Clear requirements

Determine the function, performance indicators and expected working environment of the circuit.

2. Select software

Use professional PCB design software such as Altium Designer, Eagle or KiCad to design and layout the circuit.

3. Schematic design

First draw the circuit schematic to clarify the relationship between the components.

4. PCB layout and wiring

Place the components on the PCB according to the schematic and design the circuit routing.

5. Design review

Check the electrical rules, signal integrity and other issues of the circuit design to ensure the feasibility of the design.

4. Customized PCB Process

1. File Preparation

After the design is completed, the Gerber file and assembly drawing are output, which is the basis for the manufacturer to produce the PCB.

2. Select the manufacturer

Select the appropriate PCB manufacturer according to the project requirements, budget and delivery time.

3. Quotation and order

Provide the design file to the manufacturer, get the quotation and confirm the order.

4. Manufacturing and testing

The manufacturer produces the PCB, including plate making, etching, drilling, welding and other steps, and performs electrical testing and appearance inspection on the finished product.

5. Delivery

The PCB that passes the quality control will be packaged and shipped to the customer.

5. Key considerations for customized PCB

1. Precision and tolerance

High-precision manufacturing is particularly important for complex circuits to ensure that the error in the manufacturing process is within the controllable range.

2. Material selection

Select the appropriate material according to the application requirements. Different applications may require different heat resistance, moisture resistance or high frequency performance.

3. Signal integrity

Reasonable layout and wiring to avoid signal interference and attenuation, and ensure stable operation of the circuit.

4. Cost control

The number of layers, size and special processes will affect the cost, and performance and cost need to be balanced in the early stage of design.

5. Design for manufacturability (DFM)

Production feasibility should be considered during design to avoid overly complex designs that lead to manufacturing difficulties or increased costs.

Conclusion

Customizing PCB circuit boards is a process involving design, materials, processes and other considerations. By deeply understanding the above knowledge points, you will be able to communicate more effectively with manufacturers to ensure that your circuit board design not only meets functional requirements but also finds the best balance between cost and performance. Whether it is a small project for amateurs or complex product development at the enterprise level, accurate planning and meticulous preparation are the cornerstones of success.
