Abstract

The application belongs to the technical field of circuit board production, and in particular relates to a method for embedding copper blocks in circuit boards and a tool for embedding copper blocks in circuit boards. The method for embedding copper blocks in circuit boards includes the following steps: Two core boards, circuit boards and copper blocks; the circuit board has gong grooves for accommodating copper blocks, the surface of the first core board is provided with protrusions, the surface of the second core board is provided with grooves, the height of the protrusions and The depth of the groove is equal to the height of the copper block protruding from the circuit board; then the copper block is placed in the gong groove to form a copper-embedded board; then the first core board, the copper-embedded board and the second core board are stacked in sequence , and the protrusions, copper blocks and grooves are set facing each other; then the stacked first core board, copper inlay board and second core board are placed on the press for pressing, so that the protrusions are inserted into the gong grooves After the copper block is pushed out of the surface of the copper block board, it is inserted into the groove; finally, the first core board, the copper block board and the second core board are separated, so that the height of the copper block protruding from the circuit board is controllable .

Description

Technical field[0001]The present application belongs to the technical field of circuit board production, and in particular, it relates to a circuit board of a copper block method and a circuit board of a circuit board.Background technique[0002]With the popularity of smartphone dual-camera and smart light lights, electronic components produce a lot of heat during continuous operation, if they cannot be emitted in time, it will cause the temperature of electronic components to rise sharply, affecting the use of stability and life. Circuit board failed or even damaged, a circuit board with good heat dissipation is a good solution.[0003]Copper blocks are currently typically embedded in the sink of the circuit board ("PCB") to solve the heat dissipation problem of the board. Due to the importance of the heat dissipation problem, there are also a variety of clad copper blocks in the prior art to increase the heat dissipation of the circuit board, but there are still some problems includin...
