Surface Mount Technology

August 7th Fact-of-the-Day

Nearly all electronic devices manufactured today use surface-mount technology. There are several reasons, but the primary reason is to obtain reduced physical size. Circuit board areas with surface-mount components are typically about half what they would be with through-hole components where components are mounted on only one side of a circuit board. An additional two-to-one circuit board area reduction usually can be achieved where components are mounted on both sides of a circuit board. The heights of most surface-mount components are less than the heights of comparable through-hole components. The combined effect of lower component heights and a four-to-one circuit-board area reduction with double-sided-boards results in large volume differences between equipment manufactured with surface-mount and through-hole components. ©2005 Martek International All rights reserved.
