[0002] An integrated circuit is a miniature electronic device or component. It uses a specific process to interconnect the transistors, resistors, capacitors, inductors, and other components required for a circuit, along with wiring. This process is then fabricated on one or several small semiconductor wafers or dielectric substrates, and then packaged in a tube shell to create a miniature structure with the required circuit functions. When using specialized soldering equipment to install pins on an integrated circuit chip, due to the small size of the pins and the relatively thin nature of the integrated circuit chip, operators often misalign the pins during soldering, causing unnecessary damage to the chip board and resulting in the integrated circuit chip not functioning properly.

[0027] By rotating the handle 58, the threaded rod 57 rotates, adjusting the position of the T-shaped block 55 in the slide rail 59, thereby adjusting the position of the fixing plate 52.
