Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of integrated circuit composition, and more particularly to an integrated circuit assembly test fixture. Background Art
[0002] An integrated circuit (IC) is a miniature electronic device or component. Using a specific process, the transistors, resistors, capacitors, inductors, and other components required for a circuit, along with their wiring, are interconnected and fabricated on one or several small semiconductor wafers or dielectric substrates. This is then packaged within a housing, resulting in a miniature structure that performs the required circuit functions. The structural integration of all components makes this a significant step forward in the development of miniaturization, low power consumption, intelligence, and high reliability for electronic components. The IC is represented by the letters "IC" in circuit diagrams.
[0003] When assembling irregular, polygonal, or non-rectangular parts, displacement may occur during installation due to the parts' inherent slipperiness and light weight, leading to deviation in the installation of the parts. Most parts are hard plastic substrates, and secondary tapping is very likely to result in defective products such as chipped or damaged plastic parts. In order to stabilize the parts to be processed, additional hands or labor are needed to help stabilize the parts themselves. Utility Model Content
