Csp bonding
WebDec 29, 1999 · The wire bonded chip scale package (WB-CSP) is a chip scale package using a tape wiring board, but has a fine pitch, two-row structure, and high reliability of electrode pads due to the reduction of semiconductor chip size. In order to apply the wire bonding technology. 1 shows a typical wire bonded chip scale package (WB-CSP) 100 … WebBenefits of Flip Chip. Shorter assembly cycle time. All the bonding for flip chip packages is completed in one process. Higher signal density & smaller die size. Area array pad layout increases I/O density. Also, based on the same number of I/Os, the size of the die can be significantly shrunk. Good electrical performance.
