Application of laser soldering machine in medical equipment

Regarding the application of laser soldering equipment in the field of medical equipment, medical treatment is a matter of great concern to countries all over the world. With the development of science and technology, medical equipment is becoming more and more high-end. Medical equipment is a precision instrument, and many internal parts are very precise. In response to this problem, laser soldering machines are widely used in medical equipment and other precision electronic products due to their welding characteristics.
Application of laser soldering machine in medical equipment
The structure of the medical device product is very small and the process is complicated. Therefore, the production and manufacturing processes of these equipment have strict requirements for high safety, high cleanliness and high sealing. Laser welding technology can fully meet its needs. Compared with other commonly used welding technologies, laser soldering technology hardly produces welding slag and debris, and does not need to add any adhesive during the welding process, so the entire welding work can be completed in a clean room.
 
The application of laser soldering machine in medical equipment:
1. Earwax protector
Today's typical ITE hearing aids are only the size of a little fingertip, but hearing aids all face a big problem: the earwax produced in the ear canal can contaminate the sound output area. In order to ensure that the hearing aid can perform its function, it is necessary to provide protective measures at the location of its sound output. At this time, laser technology is the most suitable choice.
2. Analytical Instruments
Analytical instruments are usually equipped with special plastic parts specially used for blood analysis. Usually the contour welding process is selected. In order to absorb the laser beam, when connecting two different parts, the transparent part must be placed on the upper side, while the lower part has the ability to absorb.
3. Balloon catheter
Balloon catheter laser soldering is soldering using infrared laser as the energy source. The laser beam can be irradiated directly on the plastic surface that absorbs the laser, so that the plastic can be melted and welded. The advanced laser soldering technology can realize the seamless connection between the balloon head and the tube body, so that the balloon catheter is not hindered when it travels in the curved, narrow and narrow diseased blood vessel, minimizing the damage to the blood vessel, and operating The process is reasonable. safer.
 4. Dispensing system
 A "drug delivery system" or drug delivery system can help patients continue to take medication. Its increasingly compact structure is more portable. Because it is directly used for patients, the requirements for hygiene are very high, and the integrated microchannel diameter is located in the area> 10μm, and the weld must be absolutely free of particles. These requirements can be met by laser technology.
5. Microfluidic components
With the help of mask welding principle, microfluidic components can be welded accurately and firmly. The geometry of the channel remains unchanged, avoiding the flow of melt into a narrow channel of only 200 µm.
