Leadless Chip Carrier

The Ceramic Leadless Chip Carrier, or CLCC or LCC, is a square or rectangular surface-mount ceramic package that has no leads.  For electrical connection the LCC instead uses flat metal contacts (or metallized castellations) known as pads around the four sides of the package bottom. LCC’s have pad counts that range from 8 to 100 with the pad pitch (distance between pads) typically either 50 mils or 40 mils. Leadless Chip Carriers are a good option for surface mount applications. The LCC can either be directly soldered onto the PCB or operated using a socket.

Advantages of LCC’s (Leadless Chip Carriers)

• Low Profile, Multilayer Ceramic Package
• Footprint Compatible with CQJB and PLCC
• Variety of Body Sizes
• Solder, Glass, or Epoxy Seal
• Castellations Instead External Leads
• Socket or Surface Mount Package
• Lead Plating: Gold or Solder Dip
