Problems solved by technology

However, in the existing BGA packaging process, since the through-hole layout of the solder ball placement tool is consistent with the pad layout of the package that needs to be solder ball mounted, it is difficult to perform solder ball bonding on packages with different pad layouts. When installing, it is necessary to make and replace different placement tools, which increases the cost of the BGA packaging process

Abstract

The invention discloses a tool for mounting a solder ball. The tool for mounting the solder ball comprises an upper solder ball mounting mould, a lower solder ball mounting mould, thimbles and a mask layer, wherein the upper solder ball mounting mould is internally provided with a plurality of through holes provided with predetermined patterns; the upper solder ball mounting mould is internally provided with a plurality of openings with predetermined patterns, and the openings formed in the lower solder ball mounting mould correspond to the through holes formed in the upper solder ball mounting mould one to one; the thimbles are arranged at the bottoms of the openings formed in the lower solder ball mounting mould; the mask layer is arranged between the upper solder ball mounting mould and the lower solder ball mounting mould and through holes with the predetermined patterns are formed in the mask layer.

Description

technical field [0001] The present invention relates to a solder ball placement tool, more specifically, the present invention relates to a solder ball that can be applied to a package structure with different solder ball numbers and solder ball layouts with the same package size and solder ball pitch Placement tools. Background technique [0002] With the development of integrated circuit technology, the packaging requirements for integrated circuits are more stringent. This is because the packaging technology is related to the functionality of the product. When the frequency of the IC exceeds 100MHz, the traditional packaging method may produce the so-called "CrossTalk (crosstalk)" phenomenon, and when the number of pins of the IC is greater than 208Pin, the traditional packaging method The method has its difficulties. Therefore, in addition to using the QFP packaging method, most of today's high-pin-count chips (such as graphics chips and chipsets, etc.) have turned to ...
