The 531X116SHAAAG2 is a thin yellow and copper-colored circuit board. The product numbers on this part are located on the top right and left-hand corners. It also has two drilled holes for mounting screws on the left-hand side of the card and a place for surface-mounting flexible pins, clips or soldering. These clips/pins require little space and give the area a little more flexibility while soldering the shield onto the clips/pins provides a more secure shielding. On the back, it is also labeled with the alphanumeric identification sequence, F31X116SHAAAGI FROO/O, the product number 531X116SHAAAG2, and SHIELD CARD 20C.
