fits both SOIC Narrow AND SOIC Wide This listing is for style #18, shown below For case: SOIC narrow, SOIC wide Includes supply rail buses to allow bypass capacitor mounting on-carrier Supply rails can be used as thermal lands to accomodate IC's with exposed metal thermal pads. These lands are "stitched" to the opposite side of the PCB with thermal vias to conduct heat away from the chip. These surfaces can also be used as ground planes in chips that don't have an exposed thermal pad. Other SMD carriers in this pin count are typically larger, and have wider row spacing, not allowing direct socketing. They require a "reducer" soldered underneath, to bring the row spacing back to 0.300" for DIP socketing. THIS carrier has the reducer built-in on the bottom of the pcb and is thus socket-ready. Direct-to-DIP14/DIP-16 socketing in a very narrow adaptor Industrial PCB assemblers use machines, not humans to place parts on a PCB. The solder is applied by silkscreening (printng like an ink) and melted by reflow systems. These systems only require IC solder pads as small as a tiny dot, and they can get the IC soldered in position every time with pinpoint accuracy.
