The advantages of femtosecond laser in micro and nano processing of probe fixtures are analyzed

A probe fixture is a tool used to test and detect electronic circuits or devices.

It is mainly composed of a probe and a bearing structure. Probes are usually made of conductive materials such as metals and have good electrical conductivity and elasticity. These probes are precisely positioned and arranged on the fixture in contact with the specific test point of the electronic component under test.

When testing, by connecting the probe fixture to the tested object, the current or signal can be transmitted through the probe, so as to detect and evaluate the performance and electrical characteristics of electronic components. Probe fixtures are widely used in the electronic manufacturing industry, especially in circuit board manufacturing, integrated circuit testing and other links, which help to ensure the quality and reliability of electronic products. It can quickly and accurately locate and test circuit problems, improve production efficiency and product pass rate.

Femtosecond laser can perform the following processing on the probe fixture:

1. Microhole machining: Tiny holes can be precisely drilled on the fixture for positioning or other functional requirements.

2. Fine cutting: Achieve precise cutting of specific parts of the fixture to meet specific shape and size requirements.

3. Surface microstructure processing: Make a variety of microstructures on the surface of the fixture to improve its performance or better match with the components under test.

Femtosecond lasers have the following advantages in the processing of probe fixtures:

1. Ultra-fine machining: It can achieve extremely high machining accuracy and meet the harsh requirements of the probe fixture for tiny structure and details.

2. Minimal heat affected zone: due to the extremely short action time, the heat generated is too late to diffuse, and the thermal impact on the surrounding materials is minimal, effectively avoiding problems such as thermal deformation, and ensuring the high precision and stability of the fixture.

3. High processing quality: can ensure the processing surface is smooth, flat, sharp edge, help to improve the performance and reliability of the fixture.

4. Non-contact processing: no mechanical stress on the fixture, reducing the potential damage to the fixture.

5. High flexibility: It can flexibly process a variety of complex shapes and patterns to adapt to the design needs of different types of probe fixtures.

6. Fast processing speed: Although it is high-precision processing, femtosecond laser can still ensure high processing efficiency to a certain extent.
