LCC IC Package Drawing

LCC Package, Surface Mount Device [SMD]

Leadless Chip Carrier IC

Leadless Chip Carrier [LCC], A surface mount device [SMD] that uses surfaces on the side of its body for board attachment and has no leads or legs. A chip carrier has terminals on all four sides of the package. Also called an LLCC, as in Lead Less Chip Carrier. The manufacturer may have an issue working with a Leadless Chip Carrier on the PWB, sometimes the solder fillet will tend to break. So check with the production department first before specifying a Leadless Chip Carrier package, to insure it is an approved package style; however, in general a surface mount package is always better than a leaded package.

Of course there are a number of different styles than those shown, but only differing in the number of pins and perhaps more rectangular than the example provided.
An LCC is related to a DLCC package, or Dual LCC package [two-sided].

The graphic to the left shows how to count the pins on an LCC package, or locate pin 1. In some cases the terminal of pin 1 is elongated to distinguish it from the other pins, as shown in the other graphics.

Note that the term Chip Carrier is a generic term that refers to a package that has terminals on all four side of its package. So there are a number of other completely different package styles that are also called Chip Carrier, or at least use the term as part of the description.
