LCC or LLCC is the abbreviation of Lead-less chip carrier. A leadless chip carrier is usually square or rectangular in shape. Unlike other integrated circuit packaging, leadless chip carriers do not establish connection to devices by means of pins, but by means studs or metal pads provided around the periphery of the package.
