Probe technology: a key tool for multi-disciplinary applications

Probe is a polysemous term whose meaning and role is understood differently in different areas of the business.wafer testing In terms of major developments, the probe technology can be categorized through the following categories:

1. Information Inspection Tools: A probe card is a test interface that is mainly used to test bare cores. Prior to packaging the IC, the probes on the probe card make direct contact with pads or bumps on the chip to generate chip signals. Automated measurements can be realized by working with surrounding test instruments and software control. For example, WiFi Probe technology is based on WiFi probing to identify nearby smart devices with WiFi turned on. Even if the user is not connected to WiFi, the WiFi Probe can recognize the user and obtain the address of the device.

2.**Biological single-stranded DNA tool* *:In biology, a probe, often referred to as a DNA probe, is the most commonly used nucleic acid probe.wafer probe It can be single- or double-stranded DNA and can be labeled with radioisotopes, fluorescent dyes, or enzymes. Under the right conditions, DNA probes can bind to target DNA sequences to form double-stranded structures that can be used for genetic testing and other applications.

3.Test PCBA Tools: In electronic testing, probes are used to test PCBAs.Depending on the use of electronic testing, probes can be categorized into various types such as optoelectronic board test probes, in-circuit test probes and microelectronic test probes. These probes have different properties and uses.probe holder For example, ICT probes are mainly used for in-circuit testing and functional testing.

4. **Computer Programming Tools**: A probe can also be a Web scripting program that implements a script file for probing sensitive server information through a Web programming language. Such probes can be used to probe a wide range of information such as web site directories, server operating systems, CPU counts, Session time-outs, and so on.

On a larger level, probes are used in several research areas development and have different roles and performance in China. In some areas, probes can also be subdivided into two different categories, each with its own specific properties and uses. No matter what the industry, probes play an irreplaceable role.
