[0002] A chip, also known as an integrated circuit, is a miniaturized form of circuitry, primarily including semiconductor devices and passive components, often manufactured on the surface of a semiconductor wafer. Pins, also called leads, are the connections from the internal circuitry of an integrated circuit to the external circuitry. All the pins constitute the interface of the chip. The end of the lead is soldered to the pads on the printed circuit board to form a solder joint. Pins can be divided into heels, toes, sides, etc.
