FAQ:
Q1: What is Surface Mount PCB Assembly?
A1: Surface mount in a PCB assembly means that each component
on the PCB is mounted on the surface of the board. In the PCB
Assembly process for surface mount components, solder paste is
placed on the PCB board at areas where surface mount components
will be placed on the board. PCB Stencils are usually used to apply
solder paste on the PCB board and a pick and place machine is used
to place SMT components on the board.
Surface Mount Assembly is very cost effective, takes up less board space and requires
short production times as compared to thru-hole assembly, as it
does not require the drilling of holes through the board. However,
the component grip is not as good as thru-hole and also the
connection can be faulty if not soldered properly.
