Tape carrier package

from Wikipedia, the free encyclopedia

The Tape Carrier Package (TCP) is a method of packaging an integrated electronic circuit (IC) in a chip package.

Electrical conductors in the form of copper are applied to a film material (tape) (more precisely: laminated ). The naked circuit (including the called) placed in the center of the film in a punched-out hole and its electrical connection points ( bumps ) connected to the conductor tracks of copper. Establishing this electrical connection is called bonding . The film is perforated at the edges for further transport during automatic assembly.

The Tape Carrier Package was originally developed for LCD drivers. Good temperature properties and a very low overall height are the advantages of the TCP.
