Surface-mount technology was developed in the 1960s. By 1986 surface mounted components accounted … See more

Where components are to be placed, the printed circuit board normally has flat, usually tin-lead, silver, or gold plated copper pads without holes, called solder pads. Solder paste, a sticky mixture of flux and tiny solder parti… See more

The main advantages of SMT over the older through-hole technique are:
• Smaller components.
• Much higher component density (components per unit area) and many more connections per component.… See more

• SMT may be unsuitable as the sole attachment method for components that are subject to frequent mechanical stress, such as connectors that are used to interface with external devices that are frequently attached a… See more

Defective surface-mount components can be repaired by using soldering irons (for some connections), or using a non-contact rework system. In most cases a rework system is the better choice because SMD work with … See more

Surface-mount components are usually smaller than their counterparts with leads, and are designed to be handled by machines rather than by humans. The electronics industry has standardized package sh… See more
