Patent ID: 8766451

Claim:
A chip packaging structure for coupling with an external circuit having a plurality of signal conducting legs, comprising: a flexible plate; a chip disposed on the flexible plate, wherein a first boundary and a second boundary are defined on the flexible plate, the first boundary is located between the chip and the second boundary, a first area is formed between the first boundary and the chip, a second area is formed between the first boundary and the second boundary, the chip including: a plurality of non-signal conducting points; and a plurality of signal conducting points; and a plurality of leads disposed on the flexible plate, including: a plurality of non-signal leads respectively extending out to the first boundary from the plurality of non-signal conducting points and selectively extending to the second area; and a plurality of signal leads respectively extending out of the second boundary from the plurality of signal conducting points and connecting with the plurality of signal conducting legs; wherein the width of the non-signal lead is smaller than or equal to the width of the signal lead in the second area, the width of the signal lead in the first area is smaller than or equal to the width of the signal lead in the second area, the width of the signal lead in the second area is smaller than the width of the signal lead extending out of the second boundary.
