Problems solved by technology

[0005] However, the joint strength between the lead and the chip bump is likely to be insufficient, so that the phenomenon of peeling between the lead and the chip bump occurs, which leads to a tape carrier package (TCP) structure or a film-on-chip package ( COF) structure manufacturing yield decline

Embodiment Construction

[0028] The first embodiment of the present invention is a chip packaging structure 1, and its cross-sectional view is as follows figure 1 shown. The chip packaging structure 1 includes a chip packaging substrate assembly 10 and a chip 11 . The chip package substrate assembly 10 includes a flexible dielectric layer 100 and a plurality of pins 102 . In practical applications, the chip package structure 1 can be a tape carrier package (TapeCarrier Package, TCP) or a chip-on-film package (Chip-On-Film, COF).

[0029] A chip bonding area 101 is defined on the flexible dielectric layer 100 . The flexible dielectric layer 100 can be an organic dielectric film layer made of materials such as polyimide (PI) or polyethylene terephthalate (PET). With the organic dielectric film layer, the pins 102 can be fixed on the chip packaging substrate assembly 10 , and the pins 102 can be electrically isolated.

[0030] In this embodiment, the pin 102 is made of a material with high conductivi...
