PCBA board production process flow

summary

PCBA (Printed Circuit Board Assembly) board production is a critical step in the electronic product manufacturing process. This article will provide a detailed introduction to the production process of PCBA boards, including the following main steps:

1. Raw material preparation

2. PCB board manufacturing

3. Component procurement

4. Component mounting

5. Process detection and testing

6. Terminal assembly

Raw material preparation
In the production process of PCBA boards, the following raw materials need to be prepared:

• PCB board

• Electronic components

• Welding materials (welding agents, solder, etc.)

PCB board manufacturing
PCB board manufacturing is the first step in PCBA production, mainly including the following process flow:

1. Design and produce PCB board prototype templates

2. Produce copper plated PCB film

3. Printed circuit patterns

4. Etching circuit board

5. Drilling

6. Surface treatment

7. Making masks

8. Inspection and repair

Component procurement
Component procurement is to obtain various electronic components required for subsequent mounting processes. When purchasing electronic components, the following precautions should be taken:

• Determine the specifications and models of the components

• Find reliable suppliers

Compare quotes and delivery times from multiple suppliers

• Quality inspection and testing

Component mounting
Component mounting refers to correctly mounting the purchased electronic components according to the circuit diagram. The process flow used in this process is as follows:

1. Punching holes

2. Bottom welding

3. Mounting

4. Roll film

Process detection and testing
At every stage of PCBA board production, necessary process testing and inspection are required to ensure that the quality and performance of the product meet the requirements. The main detection and testing processes include:

• Visual inspection

• X-ray inspection

AOI (Automatic Optical Inspection)

• Functional testing

Terminal assembly
Terminal assembly is the process of connecting a PCB board to other components or peripherals and performing the final assembly. The main process includes:

1. Connect the PCB board to other components (such as display screens, buttons, etc.)

2. Conduct final assembly

3. Conduct final inspection and testing

4. Packaging and Shipping

epilogue
The production process of PCBA board is a complex and rigorous process, and each link needs to be executed accurately to ensure the quality and performance of the final product. Through the introduction in this article, we hope to help readers better understand the steps and key points of PCBA board production.
