Beryllium copper reed design and selection - maximum shielding effectiveness

Beryllium copper reed compression force F Compression amount D Reasonable design selection of resistance R compression, the purpose of shielding is to occupy and shade the existing gap between the two connecting surfaces, in order to be effective shielding shrapnel Beryllium copper reed must occupy the largest and smallest gap, the gap exists mainly because of manufacturing tolerances, surface arrangement or irregular surface formation, appropriate compression control can ensure the effect of electromagnetic interference shielding.
In the case of maximum clearance, the compression ratio of the shrapnel must be about 25%; Shrapnel can be compressed to a height of 50% (or more).
Metal reeds are compressed in the range of 15%-60%, the compression resistance is small, and there is almost no fluctuation; At the same time, the compression force is relatively small in this range and does not increase suddenly, which is why we often recommend that customers design a clearance value of 30% compression of the material. Please consult our engineers for one-to-one design and product selection.
