SMT Surface packaging technology

Full spelling: Surface Mount Technology
Alias:

Field:
Semiconductor > basis technology > SMT

The technology which solders the electronic part of the LSI tip/chip and the like directly on the surface of the printed circuit board. Also surface mount technology technology is called.

With surface packaging technology system, surface mounted part such as tip/chip (SMD: Surface Mount Device) the solder of paste condition in order to install (it is called the pad or connected terminal) to prepare the printed circuit board which was applied beforehand, the tip/chip and the like is installed with the private catapult, [chitsupumaunta]. After that, the solder is made to melt by the fact that it heats to 250 degrees inside the hot furnace, the tip/chip and the like makes glue on the printed circuit board.

Until recently, after making the baseplate penetrate the through hole (the part hole) due to, solders the lead wire and the foot etc of the tip/chip “pin insertion system” (Through Hole Mounting Device) was used on back.
