Surface-mount technology (SMT), originally called planar mounting, is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). An electrical component mounted in this manner is referred to as a surface-mount device (SMD). In industry, this approach has … See more Surface-mount technology was developed in the 1960s. By 1986 surface mounted components accounted for 10% of the market at most, but was rapidly gaining popularity. By the late 1990s, the great majority of high-tech … 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 Defective surface-mount components can be repaired by using soldering irons (for some connections), or using a non-contact rework system. In … See more Resistors For 5% precision SMD resistors usually are marked with their resistance values using three digits: two significant digits and a … 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, … 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 … See more Surface-mount components are usually smaller than their counterparts with leads, and are designed to be handled by machines rather … See more WebSurface Mount . 5 years Electrical Performance AQL 100% Pass Solderability Per Lot Size J-STD Parts with PdAg and ENIG termination finish . ...
