SMT assembly procedure primarily consists of the following steps: solder paste printing, chip mounting, reflow soldering, cleaning, inspection and rework, all of which will be introduced in detail below.

• Solder Paste Printing

Solder paste printing refers to the process in which solder paste is placed onto PCB (Printed Circuit Board) pad through the openings on stencil. Solder paste printing is implemented by solder paste printer that is placed at the first beginning of SMT assembly manufacturing line.

• Chip Mounting

Chip mounting aims to place components onto corresponding positions on PCB compatible with design files and it is done on chip mounter that is placed after solder paste printer in SMT assembly manufacturing line.

• Reflow Soldering

In the process of reflow soldering, solder paste is first melted, making SMCs (Surface Mount Components) or SMDs (Surface Mount Devices) stuck to PCB board with solder paste cooled down. Reflow soldering is carried out in reflow soldering oven that is placed after chip mounter in SMT assembly manufacturing line
