Surface Mount Device Circuit Board

Surface mount technology smt is a method in which the electrical components are mounted directly onto the surface of a printed circuit board pcb.

Surface mount device circuit board.

Surface mount boards are also faster and easier to assemble and more cost effective than boards constructed with through hole technology. A bga has some advantages over other methods and as such it has become a favorite technique used in the manufacturing of integrated circuits and electronic devices. The following descriptions use that method and focus on a small section of a printed circuit board as shown below. 4 pack of schmartpatch for 0603 0805.

Hot air soldering is customarily used with surface mount devices being attached to printed circuit boards. However with surface mounting there is no solder plug surrounding a pin thru a hole in the circuit board to give the connection added strength. Mouser offers inventory pricing datasheets for surface mount pcbs breadboards. Ball grid array bga refers to a particular type of surface pcba which is used to permanently mount devices such as microprocessors to printed circuit boards.

Components like surface mount transistors and surface mount integrated circuits where there are leads from the device body onto the surface of the board have some means for accommodating movement but surface mount resistors and capacitors do not. Rubbing alcohol rosin core solder or 9. Solder recommend water soluble rosin core acceptable 5. Pcb printed circuit board with available pads 3.

Water for water soluble solder 10. Through hole pcb assembly is an older technology which involves attaching leads to holes drilled into the circuit board. Surface mount pcbs breadboards are available at mouser electronics. The components are soldered down tot he printed circuit board and quite rigidly held in place.

Flux w applicator 7. The same situation occurs on plated thru hole circuit boards. The top photo shows a board that has been populated and reflow soldered in an oven and the bottom photo shows the bare board.
