Housing for electro-optical devices with emi shielding
The patent US12055633B2 describes a housing designed for electro-optical devices, featuring a molded dielectric structural component that includes a top portion and two orthogonal side portions. The first side portion connects to one end of a substrate, while the second side portion connects to the opposite end. The housing incorporates an electromagnetic interference (EMI) shield and multiple conductive traces, which are strategically separated by the dielectric component. The EMI shield is positioned on the exterior surface, while at least one conductive trace is located either on the interior surface or within the dielectric component, ensuring electrical connectivity to the substrate and the optical elements of the device.
Additionally, the patent outlines a package specifically for time-of-flight (ToF) devices, which includes a substrate with a vertical cavity surface emitting laser (VCSEL) array. The housing in this configuration also features an optics assembly that secures the optical elements above the VCSEL array. The dielectric component can be made from molded dielectric polymer or dielectric film, with the EMI shield being a molded conductive polymer. The conductive traces are designed to connect electrically to both the substrate and the optics assembly, facilitating the necessary connections for the operation of the electro-optical device. The claims emphasize the innovative design that enhances the functionality and performance of electro-optical devices while addressing electromagnetic interference.
