1, silk screen (or dispensing) -> mount -> (curing) -> reflow soldering -> cleaning -> testing -> rework

2, screen printing: Its role is to solder paste or patch glue printed on the PCB circuit board pads for the preparation of electronic components welding. Equipment used for screen printing machine (screen printing machine), located in the SMT chip production line in the front.

3, Dispensing: It is the glue dripping PCB fixed position, its main role is to fix the components to the PCB circuit board. The equipment used is dispenser, located at the front of the SMT chip line or behind the inspection equipment.

4, placement: its role is to accurately mount the surface assembly components to the PCB circuit board fixed position. Equipment used for SMT placement machine, located in the SMT chip production line in the back of the screen printing machine.

5, curing: its role is to melt the chip glue, so that the surface assembly of components and PCB circuit boards firmly bonded together. The equipment used is a curing oven, located behind the placement machine in the SMT placement line.

6, reflow soldering: its role is to melt the solder paste, so that the surface assembly of components and PCB circuit boards firmly bonded together. The equipment used is a reflow oven, located behind the placement machine in the SMT line.

7, cleaning: its role is to be assembled on the PCB circuit board harmful to the human body, such as welding residues removed flux. Equipment used for washing machines, the location can not be fixed, can be online or offline.

8, testing: its role is to assemble the PCB circuit board welding quality and assembly quality testing. Equipment used are magnifying glass, microscope, on-line tester (ICT), flying probe tester, automatic optical test (AOI), X-RAY test system, function tester. Location According to the testing needs, can be configured in the production line where appropriate.

9, rework: its role is to detect PCB failure to rework. Tools used for the iron, rework station and so on. SMT chip processing factory configuration in the production line in any location.
