Hardware shrapnel stamping belongs to metal stamping parts and electronic hardware materials. English name: Metal shrapnel. The use of stainless steel or manganese materials after heat treatment is an important part of the switch. With the continuity of the metal shrapnel, it acts as a good switch between the operator and the product. At the same time, using the stable resilience (automatically returning after pressing down) and long life, the utility model provides high-quality tactile feedback for operators.
The leakage of the stamped electromagnetic wave from the metal shrapnel is actually the diffraction process of the electromagnetic wave. For the diffraction of the wave, the most critical is the relationship between the wavelength of the wave and the size of the obstacle. If the radius of the metal mesh hole is too large, the metal shrapnel can easily generate diffraction phenomena by stamping electromagnetic waves, thereby causing leakage. Hardware shrapnel stamping as the basis for electromagnetic radiation, the chassis to maintain a complete metal body, which requires the chassis to maintain good contact between any two adjacent metal sheet, we have some good quality chassis frame A lot of EMI contacts can be seen on the hardware. The metal dome stamping is used to strengthen the contact with the side plate. The closer the contact is, the better. In addition to using EMI contacts, metal shrapnel stamping quality chassis also adds EMI metal shrapnel, so it has better elasticity and contact ability, and can fully integrate the chassis frame and side panels into one, so as to effectively reduce the radiation interference. . In addition to adding EMI contacts at the side plate connections, the contacts between the metal dome stamping the ATX power supply and the chassis, the front panel drive expansion bay, and the rear panel mounting bracket must also have such contacts, so as to ensure the hardware shrapnel stamping. The tightness of the connection between the various components and effectively reduce the intensity of radiation. In addition, the hardware shrapnel stamping some chassis also try to use an integrated structure, the right side plate and the upper and lower side plates stamped with a steel plate, reducing the gap between the contact between the plates.
