1. SMT placement machines are primarily used in industry and are most prevalent in the electronics sector. What processes do SMT placement machines involve, and what effects do they have? Let’s delve into the answers from an SMT processing factory for clarity.
2. SMT chip placement machine processing is a series of technological processes applied to PCBs. It boasts high placement accuracy and speed, making it popular among electronic manufacturers. The SMT placement machine process includes screen printing or dispensing, placement or curing, reflow soldering, cleaning, inspection, and rework, with each step carried out sequentially to complete the placement task. Dipeng technicians will now organize and introduce the technological processes and functions involved.
3. SMT placement machine processing production line
1. Screen printing: The initial equipment in the SMT production line is the screen printing machine. Its primary role is to apply solder paste or adhesive to PCB pads, preparing them for component soldering.
2. Dispensing: Positioned either at the beginning of the SMT production line or following the inspection machine, the dispensing machine’s main function is to apply glue to specific locations on the PCB, securing the components in place.
3. Placement: The equipment following the screen printer in the SMT production line is the placement machine. Its primary function is to accurately position surface mount components on designated spots on the PCB.
4. Curing: The equipment situated after the placement machine in the SMT production line is the curing oven. Its main role is to heat and melt the patch adhesive, ensuring a strong bond between the surface mount components and the PCB.
5. Reflow Soldering: Positioned after the placement machine in the SMT production line is the reflow soldering furnace. Its primary function is to melt the solder paste, ensuring a solid connection between the surface mount components and the PCB.
6. Inspection: To ensure the quality of soldering and assembly of the PCB, various inspection equipment is used. This includes magnifying glasses, microscopes, in-circuit testers (ICT), flying probe testers, automatic optical inspection (AOI) systems, and X-ray inspection systems. These tools help detect defects such as soldering errors, missing solder, and cracks. These inspection devices can be strategically placed on the production line based on testing requirements.
7. Repair: Faulty PCBs requiring repair are generally handled with a soldering iron or a rework station. These can be situated at any point along the production line as needed.
8. Cleaning: Assembled PCBs may have residues such as flux that can be harmful. These residues need to be cleaned using a cleaning machine. The placement of the cleaning machine can be either online or offline, depending on the production setup.
The above content describes the technological process and functions involved in SMT placement machine processing. While the equipment used by different manufacturers may vary, the production process generally adheres to these eight key steps.
