What is the probe? What is the probe used for
The probe card is a kind of test interface, which mainly tests the bare core, connects the tester and the chip, and tests the chip parameters by transmitting signals. The probe on the probe card is directly contacted with the solder pad or bump on the chip to lead out the chip signal, and then the peripheral test instruments and software control are used to achieve the purpose of automatic measurement. The probe card is used before the IC is packaged. The probe is used for functional testing of the bare crystal system to screen out the defective products before the subsequent packaging project. Therefore, the probe card is one of the important processes in IC manufacturing, which has a considerable impact on manufacturing cost.
According to the in-depth analysis and investment strategy report of China's probe market from 2021-2026 reported by China Research Institute of Industry
Analysis of China's Probe Market
1. Statistical analysis of probe market size
Chart: Probe Industry Market Size in 2019
Data source: compiled by China Research Institute of Puhua Industry
It can be seen from the chart data that the total sales of the domestic probe market in 2019 will be about 72 million dollars, totaling about 500 million yuan. With the rapid development of the domestic semiconductor chip industry, it provides a broad market for chip packaging and testing. It is estimated that the domestic probe market will reach 550 million yuan by the end of 2020.

2. Statistical analysis of probe market demand
Chart: Market demand of chip test probes in 2019
Data source: compiled by China Research Institute of Puhua Industry
Statistics show that, from the international market as a whole, the demand for semiconductor chip test probes is only 243 millions per year (excluding aging test probes), of which the domestic market demand is about 31 millions (accounting for about 13%); The number of foreign market demands is 182 millions (accounting for about 87%). With the rapid growth and capacity expansion of domestic chip design and manufacturing in the next few years, local demand will also grow. It is estimated that the domestic probe market demand will reach 32.6 million by the end of 2020.
