Description

circuit board components

The present invention relates to a circuit board assembly, particularly a circuit board assembly including a memory slot.

With the advancement of semiconductor process technology, central processing units can support more and more memory slots. However, due to factors such as case size specifications, the space on the motherboard is often limited. In addition, when placing memory slots, you also need to consider the processor specifications and cooling requirements. Therefore, even if the CPU can support more memory slots, it is still difficult for these memory slots to be placed in the limited space of the motherboard while meeting specifications and cooling requirements.

Specifically, memory slots are usually placed horizontally along the short side of the circuit board or vertically along the long side. If the memory slots are placed horizontally along the short side of the circuit board, the number of memory slots that can be placed on the circuit board will be reduced. If the memory slots are placed vertically along the long edge of the circuit board, the wiring electrically connecting the memory slots to the processor socket may be too long and fail to comply with the processor specifications. In addition, the memory plugged into the memory slot may block the heat dissipation airflow to the processor, thereby reducing the heat dissipation efficiency of the processor.

The invention provides a circuit board assembly so that more memory slots can be placed on the motherboard while complying with specifications and not blocking the heat dissipation airflow. in limited space.

A circuit board assembly disclosed in an embodiment of the present invention includes a circuit board, a processor socket and a plurality of memory slots. The processor socket is arranged obliquely on the circuit board. The memory slot is arranged obliquely on the circuit board and is electrically connected to the processor socket.

According to the circuit board assembly disclosed in the above embodiment, the processor socket and the memory slot are arranged on the circuit board obliquely. Therefore, more memory slots can be provided on the circuit board. Furthermore, shorter wiring can be used to electrically connect the memory slots and processor sockets. In addition, the memory plugged into the memory slot will not block the cooling airflow to the processor socket. In this way, more memory slots can be placed in the limited space of the circuit board without blocking the cooling airflow.

Furthermore, the angles θ1 and θ2 between the edge 201 of the processor socket 200 and the two adjacent edges 104 and 105 of the mounting surface 101 of the circuit board 100 are, for example, substantially 45 degrees. In other words, the angles θ1 and θ2 are 45 degrees Or it may be approximately 45 degrees due to manufacturing or assembly differences.

Each memory slot 300 includes a base 310 and a latch 320 . In each memory slot 300, the latch 320 is movably disposed on the base 310. The base 310 of the memory slot 300 is disposed obliquely on the mounting surface 101 of the circuit board 100, and is used for plugging in multiple memories 20 respectively. The bases 310 of the memory sockets 300 are electrically connected to the processor socket 200 through the wirings 400 .

In this embodiment, the bases 310 of the memory slots 300 are respectively located on opposite sides of the processor socket 200 . Furthermore, one long side 301 of the base 310 of each memory slot 300 is not parallel to two adjacent edges 104 and 105 of the mounting surface 101 of the circuit board 100 . Furthermore, the angles θ3 and θ4 between the long side 301 of the base 310 of each memory slot 300 and the two adjacent edges 104 and 105 of the circuit board 100 are, for example, substantially 45 degrees.

Direction A2 is arranged on the mounting surface 101 . The first arrangement direction A1 and the second arrangement direction A2 are not parallel. That is, the short sides 302 in the bases 310 of some of the memory sockets 300 are aligned with each other, and the short sides 302 in the bases 310 of the remaining memory sockets 300 are not aligned with each other. It should be noted that in the base 310 of each memory slot 300, the short side 302 is adjacent and perpendicular to the long side 301. It should be noted that in other embodiments, all memory card slots can also be arranged in the same arrangement direction.

In this embodiment, the total length of each wiring 400 (length L1 and The sum of the lengths L2) is, for example, less than or equal to 6000 mils (mil). Therefore, the clock signal transmitted between the memory socket 300 and the processor socket 200 through the wiring 400 will comply with the specification.

The connectors 500 and 550 are respectively disposed on opposite sides of the circuit board 100 . Specifically, the connector 500 is, for example, disposed on the edge 106 of the mounting surface 101 of the circuit board 100 , and the connector 550 is, for example, disposed on the edge 104 of the mounting surface 101 of the circuit board 100 . In addition, the connectors 500 and 550 are electrically connected to the processor socket 200 . The first voltage regulator 610 and the second voltage regulator 620 are disposed on the mounting surface 101 of the circuit board 100 and between the processor socket 200 and the connector 500 . The first voltage regulator 610 and the second voltage regulator 620 are arranged in different directions and separated from each other. In addition, the second voltage regulator 620 is disposed obliquely on the mounting surface 101 . The first voltage regulator 610 and the second voltage regulator 620 are electrically connected to the memory slot 300 .

If the second voltage regulator 620 is disposed next to the first voltage regulator 610, the second voltage regulator 620 will occupy the wiring space between the processor socket 200 and the connector 500, so that the processor socket 200 and the connector 500 are It is difficult to implement the shortest wiring between 500 and 500. This embodiment enables the shortest wiring between the processor socket 200 and the connector 500 by arranging the second voltage regulator 620 adjacent to the memory socket 300 and separated from the first voltage regulator 610 .

In addition, the tilted design of the second voltage regulator 620 is to cooperate with the tilted memory slot 300 and utilize the space on the mounting surface 101 more effectively.

The third voltage regulator 630 is disposed on the mounting surface 101 of the circuit board 100 . The third voltage regulator 630 is located on a side of the processor socket 200 away from the first voltage regulator 610 and the second voltage regulator 620 . Since the wiring space between the processor socket 200 and the connector 550 is sufficient, the third voltage regulator 630 does not need to be disposed at an angle on the mounting surface 101 .

Please refer to FIGS. 2 and 3 . FIG. 3 is a partial enlarged view of the circuit board assembly in FIG. 1 from another perspective.

The second hard disk connector 800 has a second height H2 relative to the mounting surface 101 of the circuit board 100 . The first height H1 is different from the second height H2. The first hard disk connector 700 and the first mounting hole 102 define a first mounting range R1 on the mounting surface 101 of the circuit board 100 . The second hard disk connector 800 and the second mounting hole 103 define a second mounting range R2 on the mounting surface 101 of the circuit board 100 . The first installation range R1 at least partially overlaps the second installation range R2. In this way, the hard disk 30 installed on the first hard disk connector 700 and the fixing post 15 will be located between the mounting surface 101 and the hard disk 35 installed on the second hard disk connector 800 and the fixing post 16 .
