SMT production line equipment

1. Universal SMT machine: Using the program edited by the device to mount components onto designated parts positions, it can mount SOP 28 pin or more (including components that can be mounted by high-speed machines) roll, disc, or tubular packaging components. Its characteristics are high precision and diversity, but its installation speed is inferior to high-speed machines.
2. Reflow soldering: Use SMT solder paste or red glue to set an appropriate temperature curve to complete the soldering action between the solder paste and the part.
3. Unloader: The board is loaded into the magazine through a transfer track.
4. Optical inspection instrument: Automatic optical inspection is a device based on optical principles to detect common defects encountered in welding production. AOI is a new testing technology that has only emerged in recent years, but has developed rapidly. Currently, many manufacturers have launched AOI testing equipment. When performing automatic detection, the machine automatically scans the PCB through a camera, collects images, compares the tested solder joints with qualified parameters in the database, processes the images, checks for defects on the PCB, and displays/marks the defects through a display or automatic marker for maintenance personnel to repair.
