Stencil Metals Yesterday and Today
THE SHORT HISTORY OF THE
“STENCIL”
The Surface Mount Stencil industry is still
relatively new.
Since the components have no leads; there is no
need to have drilled and plated thru holes in
printed circuit boards. This is an obvious large
cost savings.
Solder joints that were formerly accomplished
by spray fluxing and wave solder machines are
now done using screen printable solder creams
and set in ovens. The new process allows very
densely populated printed circuit boards to be
assembled much faster than the old through-hole
designs, and with much higher reliability
