What is the workflow of SMT?

2024-11-18

The process flow of SMT is printing --> inspection (optional AOI automatic or visual inspection) --> placement (first paste small devices and then paste large devices: high-speed placement and integrated circuit placement) --> inspection (Optional AOI optical/visual inspection) --> Welding -> Inspection (Available for AOI optical inspection appearance and functional test inspection) --> Maintenance --> Sub-board.

The process flow is simplified as: printing-------patch-------welding-------overhaul (testing links can be added to each process to control quality)
