Description

Technical Field

[0001] This utility model relates to integrated circuit die bonding fixtures, specifically to a split integrated circuit die bonding fixture. Background Technology

[0002] Die bonding is a crucial step in integrated circuit packaging, involving attaching the chip to the package using conductive adhesive. Die bonding ensures the electrical and mechanical connection between the chip and the package, and guarantees chip stability. During manufacturing, die bonding directly impacts the yield and quality of integrated circuits.

[0003] Currently, there are three main methods for die bonding: fully automatic, semi-automatic, and manual. Fully automatic die bonding offers higher efficiency and stability compared to the other two methods, making it suitable for mass production of integrated circuits in factories and enjoying widespread market appeal. However, the die bonding fixtures currently used are relatively large, and if the housing slots of the fixture are damaged, the entire fixture needs to be disassembled and maintained, resulting in high costs. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem that existing die-attachment fixtures are large in size and require overall disassembly and maintenance when the housing slot is damaged, and to provide a split integrated circuit die-attachment fixture.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A split-type integrated circuit die bonding fixture includes a fixture base, and an integrated circuit fixing plate is detachably mounted in the middle of the fixture base;

[0007] The top of the integrated circuit mounting plate has multiple housing slots arranged in a matrix, and the bottom of the housing slots has rectangular placement blocks.

[0008] A magnetic block is embedded between two adjacent housing slots distributed along the length of the integrated circuit fixing board. The housing of the integrated circuit is placed in the housing slot and is attracted to the side wall of the magnetic block.

[0009] Furthermore, a mounting hole is provided in the middle of the fixture base;

[0010] The bottom of the integrated circuit fixing plate is provided with a fixing block that matches the mounting hole. The integrated circuit fixing plate is placed on the top of the fixture base through the fixing block and the mounting hole, and the integrated circuit fixing plate and the fixture base are fixed by multiple bolts.

[0011] Furthermore, the fixture base has a first slot and a second slot on each side for connecting to the machine tool worktable.

[0012] Furthermore, two dispensing platform lifting column slots are provided on one of the side walls adjacent to the first and second slots of the fixture base.

[0013] Furthermore, the top of the integrated circuit fixing plate is provided with tube slots distributed in a 4*5 matrix.

[0014] Furthermore, the integrated circuit mounting plate is made of brass.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The modular integrated circuit die bonding fixture provided by this utility model has a detachable connection between the fixture base and the integrated circuit fixing plate. When the integrated circuit fixing plate is worn or damaged due to use, it can be maintained or replaced by disassembling the integrated circuit fixing plate separately, which can minimize the cost waste caused by replacing the entire fixture.

[0017] 2. The split integrated circuit die bonding fixture provided by this utility model has an integrated circuit fixing plate made of brass. Because brass is soft and resistant to high temperature, it can avoid damage to the appearance of the die shell caused by the die shell groove when installing the die shell. In addition, the brass material can also withstand the high temperature during die bonding and curing. Attached Figure Description
