PCBA processing is the entire design process of PCB blank board through SMT mounting and DIP plug-in. Its processing equipment includes printing machines, dispensing machines, surface mount machines, reflow soldering machines, detection system equipment, etc. Next, we will introduce the relevant content in detail.

One、 PCBA processing

PCBA is the abbreviation for Printed Circuit Board+Assembly in English, which means that the entire design process of PCB blank board through SMT mounting and DIP plug-in, abbreviated as PCBA.

Printed circuit board, also known as printed circuit board, commonly abbreviated as PCB, is an important electronic component, electronic component support, and supplier of electronic component wiring. Because it is produced using electronic printing technology, it is called a "printed" circuit board.

PCBA processing is an electronic information processing industry with a relatively high degree of integration of mechanical technology and equipment. The use of increasingly mature processing machinery and engineering equipment, as well as the improvement of manufacturing processes, have led to continuous efforts to improve the yield of PCBA processed products, while efficiency issues have gradually increased.

Two、 PCBA processing equipment

1. Printing machine

The printing machine is located at the front end of the PCBA processing line. Mainly used for printing solder paste or adhesive on printed circuit boards. The workflow is that after aligning the template of the printing machine with the printed circuit board, the template or paste placed on the template is not printed on the printed circuit board or in the corresponding position, so that the subsequent processing components of the printing machine can be prepared for installation.

2. Glue dispensing machine

The main research purpose of glue dispensing machine is to apply solder paste or patch adhesive. The work management process involves applying different doses of glue or solder paste at the required locations for PCBA device development using the pressure of a vacuum pump. The advantage of a dispensing machine is that it does not require the replacement of self-made fixtures during the production and operation process, greatly shortening the economic cycle of enterprise production and suitable for safe production of small batches and multiple products.

3. SMT machine

Surface mount machine is the core mechanical equipment in printing processing, also known as surface mount machine. Its main purpose is to accurately remove known materials from designated locations and appropriately fix them in designated positions through pre-set conditions. The assembly and production capabilities of Pcba mainly depend on the speed and accuracy of the surface mount machine. The Pcba process is also the most technologically advanced, complex, and expensive equipment.

4. Reflow soldering machine

Its main purpose is to provide a stable and controllable heating environment, to fuse the solder pre distributed on the PCB circuit board by the printing machine together, so that SMT components and PCB pads can be reliably bonded together through solder paste.

5. Testing system equipment

The main function of the detection equipment is to detect the assembly quality and street quality of PCBA. The main equipment used includes magnifying glasses, microscopes, automatic optical detectors, online detectors, X-ray detection systems, functional detectors, etc. According to the testing requirements, its installation position is at the corresponding position behind the production line.

6. Repair equipment

The main function of rework equipment is to repair defective PCBA products. The tools used include soldering iron, BGA rework table, etc.

7. Cleaning equipment

The function of cleaning technology equipment is to remove substances that affect electrical performance or welding residues that are harmful to human health from the processed PCBA products, such as soldering flux.
