The SMD metal leaf spring SMD-M-015701225 is suitable for controllers, serving the functions of shielding external signal interference and grounding.

The PBC board on the controller contains various electronic components after封装. These electronic devices should avoid long-term static accumulation during use to prevent breakdown effects on the components and reduce the reliability of the original components. In most cases, static electricity is inevitably generated on the PCB during operation, so it is necessary to promptly discharge the static electricity.

E密斯' SMD pad SMD-M-015701225 is made of high-strength, high-conductive copper beryllium alloy, which has a lower density than traditional alloys, is lightweight, and features a coefficient of thermal expansion of 9.7x10-6m/m/℃ (20℃～200℃), ensuring minimal concern for thermal expansion and contraction due to environmental changes. The parameters of yield strength (141-152Kgf) and hardness (410-435HV) are within the excellent performance range.

The assembly method for the M-shaped grounding shrapnel during application is referenced in the diagram below. Prior to the application, ensure the PCB surface is cleaned (refer to Yili Gao cleaner). After cleaning, use solder paste to焊接 the adhesive area, then secure the shrapnel at the points where charge export is required. The specific quantity is determined based on actual testing conditions; in this case, 6 pieces were used for shielding. Once the shrapnel is applied, simply cover it with the top cover. Refer to the right-hand diagram for the illustration; the static electricity on the PCB is discharged through the metal shrapnel, forming a continuous charge between the housing and PCB, which serves to shield external signal interference and also performs grounding functions.

These metal shot particles can also be packaged using SMT reels, offering faster production, reduced labor, and better contact reliability compared to FOF, as well as superior resistance to salt spray and thermal shock, and support handheld device applications.

SMD chips, also known as PCB ground clips, are a conductive chip structure designed to prevent electromagnetic interference (EMI) from central processing units (CPUs). Leveraging the conductive properties of EMI Clips, they effectively interfere with the overflow of electromagnetic waves, meeting safety compliance standards.
