Semiconductor testing probes are mainly used in the chip design verification, wafer testing, and finished product testing stages of semiconductors. They are the core components connecting chips/wafers and testing equipment for signal transmission, and play an important role in the quality control of semiconductor products.

The structure of the probe

The probe is generally formed by three basic components: a needle, a needle tube, and a spring, which are riveted and pre pressed by precision instruments.

Due to the small volume of semiconductor products, especially the very fine size of chip products, the probe size is required to reach the micrometer level, making it a high-end precision electronic component with high manufacturing technology content.

During wafer or chip testing, probes are generally used for precise connections between wafer/chip pins or solder balls and the testing machine to achieve signal transmission and detect performance indicators such as product conductivity, current, functionality, and aging.

The appearance of probes for different purposes may vary, but the probes have a precision spring structure inside. The surface of the product is generally gold-plated, which has strong corrosion resistance, electrical performance, stability, and durability.

As a key component in semiconductor testing equipment, the structural design (such as needle shape), needle material (such as beryllium copper, phosphorous copper, etc.), and elasticity of the probe all have an impact on its stability, refinement, signal transmission accuracy, and thus affect the testing accuracy of the probe.

The position of probes in the semiconductor industry chain

Due to the complex production process of semiconductor products, any process error may lead to a large number of product quality defects and have a significant impact on the performance of terminal application products. Therefore, testing is crucial for the production of semiconductor products, running through the entire process of semiconductor product design, manufacturing, packaging, and application.

Probes are important consumables required in semiconductor testing. They are used in conjunction with testing machines, sorting machines, and probe stations for design verification, wafer testing, and finished product testing to screen out product design and manufacturing defects. They play an important role in ensuring product yield, controlling costs, guiding chip design, and process improvement.

Probe manufacturer

Due to the complex production process of semiconductor products, any errors in the process may lead to a large number of substandard product quality and have a significant impact on the performance of terminal application products. Therefore, choosing a good probe manufacturer is particularly important in semiconductor manufacturing.
