Embodiment Construction

[0022] An adjustable QFP packaging integrated circuit pin protection device dismounting tool, such as figure 1 , figure 2 As shown, it includes a support frame, a fixed end pry point, an adjustable end pry point, a displacement adjustment end, and a sliding guide rail. It is a tool for disassembling and unlocking the pin protection device through its own device design. Among them, the pin protection device is as follows: image 3 As shown, it includes the shell groove, the pin groove, and the pin fixing bayonet. The shell groove and the pin groove are respectively installed on the four sides of the device substrate, and the pin groove is fixed by the pin fixing bayonets arranged on both sides of the pin groove. One end of the pin fixing bayonet is connected to the side of the device substrate, and the other end is an acute angle edge. When the pin protection device is working, the fixing bayonet catches the pin groove to protect the pins.

[0023] In the disassembly tool, th...

Abstract

The invention discloses an adjustable assembling and disassembling tool for a pin protection device of a QFP encapsulated integrated circuit. The adjustable end pry point is driven through a displacement adjusting platform, the adjustable assembling and disassembling tool can adapt to the specifications of various types of pin protection devices, and the working space for assembling and disassembling can be freely adjusted; an acute angle edge of a fixing bayonet of the protection device is ejected through the adjustable end pry point so as to realized the automatic assembling and disassembling of the protection device; and the structure is simple, the dismounting and mounting effect is good, and the problem that the existing manual assembling and disassembling easily damages a pin is avoided.

Description

technical field [0001] The invention relates to an adjustable QFP packaging integrated circuit pin protection device disassembly tool, which belongs to the field of circuit tooling. Background technique [0002] Quad flat pack (hereinafter referred to as QFP) refers to a plastic thin packaging form with a square or rectangular shape and wing-shaped short leads on four sides. QFP packaging is a common packaging form for military and aerospace integrated circuits. It is small in size, small in parasitic parameters, suitable for high-frequency use, and high in reliability. Common forms include QFP24, QFP32, QFP48, QFP68, etc. The difference between different specific packaging forms mainly lies in the shell volume and the number of pins. [0003] The pins of QFP packaged integrated circuits are generally long and soft, and are easily deformed by external forces. In order to protect the pins, QFP packaged devices generally have a dedicated pin protection device. Put all the int...
