What Does Leadless Chip Carrier (LCC) Mean?
A leadless chip carrier (LCC or LLCC) is an integrated circuit package that has no pins/leads for contact. This surface-mount device makes use of metal pads at the outer edges to establish connection with the circuit board. Leadless chip carriers are popular, as they are light in weight, adaptable to a wide range of applications and are considered ideal for surface-mount applications.
Techopedia Explains Leadless Chip Carrier (LCC)
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. Due to reduction in weight, area and volume, leadless chip carriers are more durable and could withstand more vibration and shock compared to dual-in-line packages.
