Geometry Driven EMI Shielding with Form-In-Place Gaskets
This white paper examines challenges in electromagnetic interference (EMI) shielding caused by gaps in electronic enclosures and the limitations of conventional conductive silicone gaskets, which often become rigid and require high assembly force. It introduces Trishield®, a magnetically shaped form-in-place gasket that aligns conductive particles using a magnetic field to create a high height‑to‑width triangular structure. This design enhances flexibility, compressibility, and shielding effectiveness while reducing material usage, weight, and assembly complexity. Trishield® enables reliable EMI protection across industries such as telecommunications, automotive, and aerospace, supporting lightweight, compact, and high‑performance electronic device design.
