Board Level Shields
Precision Board Level Shields for EMI & RFI Interference Protection
Speak With An EngineerWhat Are Board Level Shields?
Board level shields are compact, precision-engineered metal enclosures designed to protect sensitive components on printed circuit boards (PCBs) from electromagnetic interference (EMI) and radio frequency (RF) disturbances. Commonly known as PCB shielding cans, these shields are essential for maintaining PCB EMI shielding effectiveness by containing and blocking unwanted electromagnetic signals that can cause performance degradation or data errors. Board level shields play a crucial role in maintaining the integrity of the PCB by minimizing crosstalk between components, mitigating EMI, and ensuring reliable operation in complex electronic assemblies.
Widely used across various industries, including telecommunications, medical devices, consumer electronics, and aerospace, board level shields help manufacturers meet stringent regulatory standards and enhance overall product performance. By providing targeted protection directly on the PCB, these shields enhance signal integrity and reduce the risk of interference affecting sensitive circuits. Their precise design and robust materials allow for efficient grounding and long-term durability, making board-level shields a trusted solution for safeguarding high-performance electronics in demanding applications.
