Introduction to Common Equipment in PCBA Processing

PCBA processing is a crucial link in the manufacturing of electronic products, and high-quality PCBA processing cannot be achieved without the support of advanced equipment. This article will introduce several commonly used PCBA processing equipment to help readers better understand the key equipment required in the PCBA processing process.

1. Soldering equipment

1.1 Surface Mount Technology (SMT) Equipment

SMT equipment is one of the most commonly used equipment in PCBA processing, including placement machines, reflow ovens, etc. The placement machine is used to accurately mount SMD components on the PCB board, while the reflow oven is used to melt the solder paste and solder the components by heating to ensure the quality and stability of soldering.

1.2 Wave soldering equipment

For PCBAs that are soldered by wave soldering process, wave soldering equipment is indispensable. It realizes the soldering of plug-in components by placing the PCBA board in the solder surge, which is suitable for some occasions with high requirements for soldering quality.

2. Inspection equipment

2.1 AOI inspection equipment

AOI (Automated Optical Inspection) is an automatic optical inspection technology, which is mainly used to detect the soldering quality, component position, etc. on the PCBA board. Through high-resolution image acquisition and analysis, AOI equipment can quickly and accurately find potential defects and improve product quality and production efficiency.

2.2 ICT test equipment

ICT (In-Circuit Test) is a commonly used test method in the PCBA process, which is used to detect electronic components and circuit connections on the circuit board. ICT test equipment introduces test probes to perform circuit connection tests, helping to find fault points and defects on the circuit board to ensure product quality.

3. Production auxiliary equipment

3.1 Solder paste printer

The solder paste printer is used to accurately apply solder paste on the PCB board to ensure soldering quality and reliability. It evenly applies solder paste to the soldering area of the PCB board through a template or spraying method, providing a good foundation for subsequent component mounting.

3.2 Cleaning equipment

After the PCBA processing is completed, in order to ensure the cleanliness and quality of the product, it is often necessary to use cleaning equipment for cleaning. Cleaning equipment cleans the residue on the PCBA board by spraying, soaking and other methods to ensure the appearance and performance of the product.

Conclusion

The common equipment in PCBA processing covers soldering, testing and production assistance. Each equipment plays an important role in ensuring the quality and production efficiency of PCBA products. Understanding the functions and characteristics of these equipment will help companies choose suitable equipment and improve the efficiency and quality level of PCBA processing.
