Staggered-pins structure for substrate

Abstract

The invention discloses a staggered-pins structure for a substrate; in the staggered-pins structure for the substrate, a solder pad arranged on a chip of the substrate is electrically connected with a pin by a bonding lead; the pin is connected to an external circuit through a circuit line, wherein each pin is in regular hexagon shape; a plurality of pins are staggered along an arrangement direction of the solder pad on the chip; according to the staggered-pins structure for the substrate, the space of the pin part can be utilized in maximum so as to realize high-density encapsulation; in addition, the size of an encapsulation piece can be reduced.

Description

technical field

[0001] The invention belongs to the technical field of semiconductor packaging, in particular, the invention relates to a staggered pin structure for a substrate of a semiconductor package capable of realizing high-density integration. Background technique

[0002] As electronics become smaller, denser and perform better, semiconductors become proportionally smaller as their components and connections become denser. Generally, in order to realize circuit connection, bonding wires are used to connect substrate pins and chip ports through a wire bonding process. The wire bonding process is the use of bonding wires to connect the terminals of an integrated circuit (IC) chip (hereinafter referred to as "pads") to corresponding pins (sometimes referred to as "pads") such as a substrate or printed circuit board (PCB). wire bond pads” or “bond pads”) interconnections are known methods.

[0003] Conventional pads for wire bonding are regularly arranged, and the lea...
