A semiconductor test probe is a tool used to test semiconductor chips. （pogo pin malaysia）They are usually made of metal and have long, thin tips that make contact with pins on the chip. Semiconductor test probes are designed and manufactured with great precision to ensure accurate and reliable testing of chip performance and functionality.

There are many types of semiconductor test probes, each with its specific purpose and benefits. Here are some common semiconductor test probe types:

Needle Probe: This is the most common type of semiconductor test probe. They're usually made of tungsten or steel and have slender tips that make contact with pins on the chip. Needle probes are suitable for testing chips with large pin spacing, such as integrated circuits.

Spring Probes: These probes use springs to provide contact force with the chip pins. Spring probes are suitable for testing chips with small pin spacing, such as microprocessors. They provide a more stable contact force and reduce the risk of damage to the chip.

Magnetic probes: These probes are made of magnetic materials that can make contact with the pins on the chip through magnetic force. Magnetic probes are suitable for testing high-density chips, such as memory chips. They can provide higher testing speed and better accuracy.

Vacuum Probe: This probe uses vacuum technology and can be tested in a vacuum environment. Vacuum probes are suitable for testing chips that are very sensitive to environmental conditions, such as optoelectronic devices. They provide more stable test results and reduce external disturbances.

In addition to different types of probes, semiconductor test probes come in different sizes and shapes.

Generally speaking, the smaller the size of the probe, the smaller the chip that can be tested, but it will also increase the difficulty of manufacturing and operation.

The manufacturing process of semiconductor test probes is very complex and requires high-precision machining and assembly techniques. Manufacturers typically use micro-nanofabrication techniques to fabricate the tip of the probe and use precision instruments to test and calibrate the probe's performance. These probes are often fabricated in arrays to test multiple chips simultaneously.

In summary, semiconductor test probes are a key tool for testing the performance and functionality of semiconductor chips. They come in many types and sizes, and each type has its specific uses and advantages. Manufacturing semiconductor test probes requires high-precision machining and assembly techniques. With the continuous development of semiconductor technology, semiconductor test probes are constantly innovating and improving to meet the ever-increasing testing requirements.
