New description: [New technical field] The present invention relates to an electrical connector assembly, and more particularly to an electrical connector combination having a signal adapter plate. ^ [Prior Art] In order to improve the signal transmission speed, the current computer system's integrated circuit unit (central processing unit, CPU) conduction pin uses the flat pad-type planar contact point instead of the traditional one. Pin-type plug. Moreover, due to the miniaturization of the CPU toward the size, as the CPU size shrinks, the spacing between the conductive points on the surface becomes narrower and narrower. The conventional ball grid array (BGA) packaging technology Because of the limitation of the volume of the solder ball, it has not been applied to the packaging process of the socket connector and the circuit board with narrow spacing of the conductive terminals. Accordingly, a planar grid array (LGA) socket connector is developed correspondingly for the CPU to be electrically connected to the circuit board. • The conductive terminal of the LGA socket connector has a first crimping portion for electrical connection of the CPU and a second crimping portion electrically connected to the circuit board. The circuit board is plated with thick gold (Au) corresponding to the second crimping portions as a guiding point, and utilizes the superior conductive properties of gold to improve the electrical conductivity between the conductive terminals and the circuit board. Since the socket connector is electrically connected to the board in a crimped manner, there is a resettable advantage in the process, that is, it can be easily replaced on a different board. However, the grid-shaped junction point (thick gold) on the board is only a small area of the board, and the 5 M294118 between the junctions must be controlled at a predetermined distance. In order to insulate the respective conductive points from each other. Therefore, it is necessary to plate the conductive points on only a small area on a large-area circuit board. In addition to avoiding the other areas of the circuit board being keyed, it is necessary to accurately control the distance between the conductive joints, making the process more difficult to control. The product yield is low, which leads to an increase in process time and cost. In addition, because of the large board area, large-scale plating equipment is required for processing, which also increases the cost of using the equipment. - [New content] Therefore, the purpose of the present invention is to provide a signal adapter board that is easier to control, _, can reduce process time and cost, and utilize the signal adapter board to connect the socket connector and the circuit board. Electrically connected electrical connector combination. The present invention is suitable for electrically connecting an integrated circuit package to a circuit board, the electrical connector combination comprising: a socket connector and a signal adapter plate.

The insulating base has a bottom wall and defines a mounting surface on which an integrated circuit package can be mounted. Each of the conductive terminals is fixed to the bottom wall and has a convex shape respectively. And a second crimping portion extending from the opposite sides of the bottom wall, wherein the first crimping portion is used for crimping the integrated circuit package. The signal transfer board includes a board body and a plurality of lead units. The board has a first contact surface for assembly of the socket connector and a second contact surface for assembly with the circuit board. Each of the guiding units has a guiding point on the first contact surface, and a soldering point on the second contact surface corresponding to and electrically connected to the guiding point. Each of the guiding points is made of a conductive metal for crimping the first crimping portions of the conductive terminals, and each of the soldering points is soldered to the circuit board.

One side of the chamber 214 is defined as a mounting surface). The bottom wall 211 forms a terminal receiving groove 213 of the conductive terminal 22 such as a plurality of valleys, and each of the conductive terminals 22 is fixed to the terminal receiving groove 213 of the bottom wall 211 and has one of opposite sides of the bottom wall 211 respectively. The first crimping portion 221 and the second crimping portion 222 are used for crimping the guiding points 91 of the integrated circuit package 9 , and the second crimping portion 222 is used for the signal adapter board 3 crimping.

Each of the guiding units 32 has a guiding point 321 of the first contact surface 311, and a soldering point 322 located at the second contact surface 312 and corresponding to the guiding point 321 and electrically connected. Each of the guiding points 321 is made of a conductive metal for crimping the second crimping portion 222 of each of the conductive terminals 22. The conductive contacts 321 are made of gold (Au) material and are preferably 7 M294118. . Each solder joint 322 can be soldered to the circuit board 8 by a solder ball 7. In this embodiment, each of the solder joints 322 is located directly below the corresponding lead-points 321 and is electrically connected by respective conductive wires (not shown) that extend through the board body 3''.

The board 8 is connected, and is not affected by the size reduction of the integrated circuit package 9. Moreover, since a heat sink such as a fan is mounted on the integrated circuit package 9, the area of the circuit board 8 is larger than that of the integrated circuit package. 9. The k-plate adapter plate 3 can utilize the smear; # use the area of the eve to enlarge the distance between the solder joints 322 #, and does not increase the area estimated on the circuit board 8. The guiding point 321 can be easily formed by a small area of the signal adapter board, and the wiring layer 313 can be enlarged by using a multi-J layer of the jade layer, and the spacing of the soldering points 322 can be applied. The BGA process can reduce the daily schedule and cost of the process, so it can achieve the purpose of this new type.
