Leadless Chip Carriers (LCC) are low profile multilayer packages used in surface mount applications or socketing. Due to their light weigh, low cost, and lead counts from 3 -84, they are suitable to a variety of applications. LCC’s have no metallic external leads and instead offer short internal electrical traces from the die to the metalized castellations around all 4 sides and bottom of the package. These contacts are normally .040” - .050” on center. JEDEC outlines come in different configurations with Type C the most popular.
