Abstract
A printed circuit board (PCB) prevents damage to tabs of the PCB and pins of a slot by reducing insertion force when the PCB is inserted in the slot. The PCB includes a body portion including a first surface and a second surface and a metal interconnection layer formed on at least one of the first and second surfaces. The metal interconnecting layer includes tabs formed along a first edge of the body portion. An insertion force alleviation portion in which at least a portion of the body portion is removed is formed in the first edge to reduce the insertion force required to seat the PCB within the slot.
Claims14
A printed circuit board (PCB) comprising:
- a body portion comprising a first surface and a second surface opposite to the first surface;
- and a metal interconnection layer formed on at least one of the first and second surfaces, the metal interconnection layer comprising a plurality of tabs formed along a first edge of the body portion, wherein an insertion force alleviation portion is formed in the first edge of the body portion, below the metal interconnection layer, to reduce an insertion force required to seat the PCB, wherein the insertion force alleviation portion comprises at least one partial-thickness or full-thickness cutout, wherein each of the plurality of tabs includes a tie-bar extending therefrom to a bottom end of the body portion, and wherein each of the at least one partial-thickness or full-thickness cutout is disposed only within a portion of the body portion that is defined by one of the plurality of tabs and its corresponding tie-bar extending therefrom.
a system comprising:
- a main board;
- at least one slot installed on the main board;
- and a printed circuit board (PCB) on which at least one memory chip is mounted, the PCB comprising an insertion portion that is configured to be received into the at least one slot, the insertion portion comprising grooves or holes that are formed in a first edge portion of the insertion portion, wherein the grooves or the holes are configured to provide a reduced physical resistance to pins of the at least one slot when the PCB is inserted into the at least one slot, wherein the PCB further comprises a plurality of tabs for electrically connecting the PCB to the main board, wherein each of the plurality of tabs includes a tie-bar extending therefrom to a bottom end of the PCB, and wherein each of the grooves or the holes is disposed only within a portion of the PCB that is defined by one of the plurality of tabs and its corresponding tie-bar extending therefrom.
a printed circuit board (PCB) having a structure that is configured to be received by a slot, wherein a plurality of tabs are formed on a first edge portion of the PCB, which is inserted into the slot, and grooves or holes for reducing physical resistance to pins of the slot when the PCB is inserted into the slot are formed in the first edge portion according to a predetermined disposition rule with respect to the plurality of tabs, wherein each of the plurality of tabs includes a tie-bar extending therefrom to a bottom end of the PCB, and wherein each of the grooves or the holes is disposed only within a portion of the PCB that is defined by one of the plurality of tabs and its corresponding tie-bar extending therefrom.
a printed circuit board (PCB) comprising:
- a body portion comprising a top surface, a bottom surface opposite to the top surface, a front surface, and a back surface opposite to the front surface;
- one or more packaged microchips arranged on the front surface of the PCB, the back surface of the PCB, or on both the front and back surfaces of the PCB;
- a plurality of metal leads formed on a lower portion of the front and back surfaces of the PCB, proximate to the bottom surface of the PCB;
- and one or more partial-thickness or full-thickness cutout formed in the bottom surface of the body portion, below the metal leads, wherein each of the plurality of metal leads includes a tie-bar extending therefrom to the bottom surface of the PCB, and wherein each of the one or more partial-thickness or full-thickness cutout is disposed only within a portion of the PCB that is defined by one of the plurality of metal leads and its corresponding tie-bar extending therefrom.
