SMT is surface mount technology (short for Surface Mount Technology) and is currently
the most popular technology and process in the electronics assembly industry.
SMT includes surface mount technology, surface mount equipment, surface mount components,
and SMT management. Features: high assembly density, small size and light weight of electronic
products. The size and weight of patch components are only about 1/10 of that of traditional
plug-in components. After SMT is generally used, the volume of electronic products is reduced
by 40%~60%, and the weight is reduced by 60%. %~80%. High reliability and strong anti-vibration
ability. The solder joint defect rate is low. High frequency characteristics are good. Reduced
electromagnetic and radio frequency interference. Easy to automate and increase productivity.
Reduce costs by 30% to 50%. Save materials, energy, equipment, manpower, time, etc.
A whole semi-automatic SMT line include semi-automatic printer, conveyor, pick and place
machine and reflow oven
So what is the Semi-automatic printer?
Modern solder paste printing machines are generally composed of plates, tin paste, embossing,
and transmission boards. Its working principle is: firstly, the circuit board to be printed is fixed
on the printing positioning table, and then the solder paste or the red glue is printed on the
corresponding pad through the steel mesh by the left and right scrapers of the printing machine,
and the PCB which is uniformly printed is passed through. The transfer station is input to the
placement machine for automatic placement.
