Probe technology: a crucial link that cannot be ignored in chip manufacturing

Time:2025-07-25Reading:746Second


In today's rapidly developing technology, chips have become the "brain" of the digital age. From smart phones to supercomputers, from smart appliances to autonomous vehicle, chips are everywhere. However, few people know that the birth of every qualified chip relies on a seemingly small but crucial component - the test probe.

Probe Testing: Guardian of Chip Quality    



Chips must go through a strict testing process before mass production, and testing probes play a key role in it. Its working principle seems simple: using test probes to make precise contact with chip pads, transmitting test signals, and detecting various performance indicators of the chip. However, this process involves extremely high technical requirements:

Wafer Testing (CP):Before chip cutting and packaging, thousands of probes on the probe card simultaneously contact the chips on the wafer for preliminary screening, effectively avoiding defective products from entering the subsequent high cost packaging process.

Final Test (FT):After the packaging is completed, the probe conducts a comprehensive functional verification of the chip again to ensure that the product fully meets the design specifications.

A reliable and stable testing probe is a key factor in ensuring chip yield, and its performance directly affects the quality and cost of the product.
