Micro-SD To Secure Digital Adaptor Card And Manufacturing Method

A microSD-to-SD adaptor card includes a base substrate having a lead frame structure, a protective cap forming a chamber that encloses eight microSD contact pins of the lead frame structure, and a thermoset plastic casing formed over the protective cap and exposed portions of the base substrate to provide the adaptor card with standard SD card dimensions. A rear opening facilitates insertion of a standard microSD card, whereby the eight contact pads on the microSD card are contacted by the eight microSD contact pins inside the chamber to allow electrical signals generated by the microSD card to be transmitted to a host system by way of a standard SD socket. A grip anchor pin is disposed inside the chamber to engage a grip notch disposed on the microSD card. A pre-molded switch slot is provided on the molded plastic casing, and an insert-in write protect switch is mounted after molding.
