Choosing the appropriate wireless antenna and using appropriate operating methods can ensure good wireless characteristics.
The quality management of twisted spring wireless antennas is crucial because twisted spring wireless antennas are manufactured using coil inductors of spring pressing machines, which means that the wireless characteristics of each batch may not be completely consistent. At this point, quality management seems particularly important. Technical professional wireless antenna companies will conduct purposeful quality management inspections to ensure the consistency of wireless antenna characteristics, while non-technical companies usually do not have this aspect of control.
The welding of twisted spring wireless antennas is also a very important step, because the characteristics of wireless antennas determine that even if the wireless antenna is welded to the same part, if the welding direction and method are not consistent, it will still cause differences in the characteristics of the wireless antenna. How big is the actual difference of this kind? Everyone can come and conduct an experiment. Weld the same wireless antenna to the same part of the test board, but the welding direction of the wireless antenna is intentionally different.
The same wireless antenna is welded to the same part of the same detection circuit board by electric welding, and there is only a certain difference in the welding direction. However, in this case, there is also a significant difference in the series resonance of the wireless antenna in the test. It can be seen that when using torsion spring wireless antennas, if the welding method is not consistent, it can also cause wireless antenna characteristic problems.
This requires us to ensure that the welding direction of the wireless antenna in mass production is consistent with the welding direction of the antenna manufacturer when selecting the wireless antenna, especially when assisting with repair welding by contract manufacturing companies. Only then can we ensure the consistency of the wireless antenna characteristics.
In fact, the selection of twisted spring wireless antennas mentioned earlier requires professional adjustment and selection, and the issue of maintaining consistency in installation orientation during the application of twisted spring wireless antennas is not a unique issue for twisted spring wireless antennas. All embedded wireless antennas have the above problems, which are also caused by the physical and chemical factors of wireless antennas. For example, FPC wireless antenna is also a commonly used embedded wireless antenna design scheme. If an FPC wireless antenna is not designed and adjusted, it is likely that the characteristics of the wireless antenna will not be high due to mismatched characteristic impedances. FPC wireless antenna will also have inconsistent characteristics between wireless antennas due to inconsistent adhesive positions and orientations. This situation is all determined by the characteristics of the wireless antenna itself, and everyone can only completely use methods and methods to get rid of it.
