What is the best way to choose a domestic probe station?

An essential function of the domestic probe station is to provide a test platform to test semiconductor chips' electrical parameters, which can be connected to various measuring instruments. With the measuring instruments, integrated circuits can be measured for voltage, current, resistance, capacitance-voltage characteristic curves, and they can also be used to test probe chips, wafers, and devices nondestructively at room temperature.

With the continuous development of electronic technology, the semiconductor market is gradually opening up and growing. As a necessary instrument for semiconductor testing, the market for probe stations is also growing and expanding year by year, so in recent years, the scale of domestic probe stations in the semiconductor test instrument market is also expanding year by year.

What are the advantages and disadvantages of domestic electronic probe station?


1. A homemade probe station that is cheaper.

Sample holder can accommodate wafer samples up to 8 inches with a stable dual displacement adjustment system. The X-Y axis can be moved by 50mm by moving the slide under the sample holder, and the sample holder can be fine-tuned in three dimensions, making sample testing and replacement easier.

In order to prevent magnetic interference caused by magnetic adsorption, the probe arm's base is fixed with screws. As the vacuum adsorption cannot be fixed without turning on the vacuum pump, the probe can be adjusted in the three-dimensional space X-Y-Z,micromanipulator which can be turned 360 degrees.

Also, the probe can be adjusted in three-dimensional space in the X-Y-Z direction, can be rotated 360 degrees, and can be shifted to meet the requirements of rapid insertion into arbitrary positions of the sample.

Leakage is extremely small.

The disadvantages are:

As different types of enterprises have different advantages and disadvantages of the probe stage, the main development of the probe stage depends on the test's needs and the student's education level.
