Now is the era of intelligent mechanization. Much of production relies on machinery and equipment, such as manipulators that use various chips! In the process of PCBA circuit board production, extensive machinery and equipment are required to assemble each board. Often, the quality of a factory’s machinery and equipment directly impacts its manufacturing capacity. PCBA processing includes the following information:
The basic equipment required for PCBA production includes solder paste printers, placement machines, reflow soldering ovens, AOI detectors, component angle cutters, wave soldering machines, tin furnaces, plate washers, ICT test fixtures, FCT test fixtures, and aging test racks. The equipment provided will vary depending on the size of the PCBA processing plant.
Analyzing the electronic accessories and consumables needed for PCBA circuit boards:
1. **Solder Paste Printer**
Modern solder paste printers typically consist of plate loading, solder paste application, imprinting, and circuit board transfer. The working principle is as follows: First, the circuit board is fixed on the printing positioning table. Then, solder paste or red glue is applied to the corresponding pads through the stencil using the printer’s left and right scrapers. The printed board is then transferred to the placement machine for automatic placement.
The cleaning processes involved in the solder paste printer include: bottom wiping of the solder paste printer (using water-based cleaning agent W2000) and offline cleaning of the solder paste stencil (using W1000/EC-200).

2. Mounter
Mounting machine, also known as “placement machine” or “Surface Mount System,” is configured after the solder paste printer on the production line. It uses a placement head to accurately position surface mount components onto the PCB pads. There are two types: manual and automatic.
3. Reflow Soldering
Reflow soldering features an internal heating circuit that heats air or nitrogen to a sufficiently high temperature, which is then blown onto the circuit board where components have been placed. This process melts the solder on both sides of the component, allowing it to bond to the motherboard. The benefits of reflow soldering include precise temperature control, prevention of oxidation during soldering, and easier management of manufacturing costs.
4. AOI Automatic Optical Inspection
AOI (Automatic Optical Inspection) is a technology based on optical principles used to detect common defects in soldering production. Although it is a relatively new technology, it is advancing rapidly, and many manufacturers now offer AOI equipment. During automatic inspection, the machine scans the PCB with a camera, captures images, and compares the solder joints to predefined parameters in a database. After image processing, the machine identifies defects and either displays them or marks them for repair by maintenance personnel.
