Abstract
A paddle card includes a printed circuit board (PCB), a shielded cable, and an electromagnetic interference (EM) shield. The PCB includes a first metal layer on a top surface of the PCB, a second metal layer within the PCB, and a cavity in the top surface of the PC. The cavity exposes the second metal layer. The first metal layer includes a first ground pad. The second metal layer includes a signal pad located within the cavity. The shielded cable includes a signal conductor coupled to the first signal pad. The EMI shield is coupled to the ground pad and covers the cavity.
Claims20
A paddle card, comprising:
- a printed circuit board (PCB) including a first metal layer on a top surface of the PCB, a second metal layer within the PCB, and a first cavity in the top surface of the PCB, wherein the first cavity exposes the second metal layer at a first location, wherein the first metal layer includes a first ground pad and the second metal layer includes a first signal pad located within the first cavity;
- a first shielded cable including a first signal conductor coupled to the first signal pad;
- and
- a first electromagnetic interference (EMI) shield coupled to the first ground pad and covering the first cavity.
A method for assembling a paddle card, the method, comprising:
- providing, on the paddle card, a printed circuit board (PCB);
