Shielding Material For Finger Reed Protection Applications

In today's era, electronic products and electronic equipment technology are constantly developing rapidly, so the demand for various electromagnetic shielding technologies is increasing. Speaking of electromagnetic shielding, the first thing we generally think of is EMI (electromagnetic interference), but in fact, in the field of shielding, there are RFI (radio frequency interference), EMC (electromagnetic compatibility) and finger reed (electromagnetic pulse), which are several common electromagnetic shielding needs.
This article is going to talk about the product that focuses on the application of finger reed, first briefly talk about what is finger reed, and the characteristics of finger type reed products. Simply put, finger reeds are short-term, high-energy electromagnetic shock waves, which will cause overcapacity and overload destructive effects on parts in various precision electronic equipment, especially on semiconductor parts of MOS technology. This is also the main principle that modern armies will configure finger reed weapons and carry out electronic warfare. Moreover, not only finger reed weapons will produce finger reed interference, but also many environments will have similar situations, such as nuclear bomb explosions, high-altitude thunderstorms, sunspot bursts, etc., where there are related application needs, finger reed protection is required.
So, what kind of product or material is suitable for finger reed protection applications? Starting from the characteristics of finger reeds, it is obvious that what is needed is a product that can quickly derive a large amount of electromagnetic energy in a short time, and the shielding efficiency must be high enough to attenuate most of the electromagnetic energy. Moreover, in terms of structural design, the conductivity of the shielding layer should be continuous, and the shielding layer and the equipment compartment should be insulated. Therefore, this finger reed application is usually selected for metal materials, while ensuring high ampacity, high shielding efficiency and high electrical conductivity.
