Description

Technical Field

[0001] The utility model relates to the technical field of chip testing, in particular to a chip testing fixing seat. Background Art

[0002] The LIV test system combines multiple instruments, including instruments for testing the DC characteristics, optical power and strict temperature control of laser diode modules. Keithley's LIV (Light Intensity-Current-Voltage) test system is used to meet the production test requirements of laser diode module (LDM) manufacturers, enabling them to increase production and revenue.

[0003] Integrated circuits have two main advantages over discrete transistors: cost and performance. The low cost is due to the fact that the chip has all the components printed as a unit through photolithography, rather than making only one transistor at a time. The high performance is due to the components switching quickly, consuming less energy because the components are small and close to each other. In 2006, the chip area ranged from a few square millimeters to 350 mm², and each mm² could have up to one million transistors.

[0004] When the chip is tested, workers are required to manually press the connecting plate onto the adapter plate and the substrate. Due to the manual operation of the workers, the adapter plate and the substrate become unstable when connected, which in turn causes voltage instability, affecting subsequent tests and causing inconvenience in use.
