Order information

LST Technology specializes in the production and processing of medical PCBs. MRI motherboards are used on MRI instruments, which are the core components of the equipment and control the operation of the entire instrument.

A nuclear magnetic resonance (NMI) instrument is an instrument used to measure and analyze nuclear magnetic resonance phenomena. It is mainly composed of a magnet, radio frequency field generator, receiver and signal processing computer, etc. The NMI instrument uses the spin motion properties of atomic nuclei. Different atomic nuclei have different stable energy states, and when placed in a magnetic field, they will resonate at different frequencies. This resonant frequency is known as the Larmor frequency.

NMI technology has a wide range of applications in physics, chemistry, biology and medicine. In chemical analysis, NMI can be used to determine the structure of molecules. In biology, NMI can be used to study the structure and dynamics of biological macromolecules. In the medical field, NMI is also widely used for imaging the internal tissues of the human body and diagnosing diseases.

NMI imaging technology is a medical imaging technology using the NMI principle, which generates a radiofrequency magnetic field around the human body to resonate with the hydrogen nuclei inside the human body, thus obtaining an image of the inside of the human body.NMI imaging technology has the advantages of high resolution, no radiation damage, etc., and can be used to detect a variety of diseases, such as tumors, brain diseases, and joint diseases.

Manufactured using the crimping process

The main board of the MRI machine is manufactured using the crimping process, which is technically safer and more reliable. Crimping is a technique in which a tool or device is used to connect wires to terminals by compressing and displacing the metal within specified limits through compressive force. Benefits of this process include reliable connections, high productivity and the ability to adapt to automated production. Crimping is used in a wide range of electrical, medical, electronic and automotive applications.

Technical advantages of the crimping process

1.High reliability: crimp connector technology is reliable, even in high vibration and thermal cycling environments.

2. High repeatability: crimp connector technology ensures a perfect fit every time, the failure rate is 100 times lower than hand-soldered components, the technology eliminates any risk of imperfect surface-to-surface bonding and improves the reliability of electronic components.

3.High flexibility: crimp connector technology for a variety of PCB thickness leaves room for one or both sides of the receiving PCB, and these components are also suitable for mass production.
