Description

Technical Field

[0001] The utility model relates to the technical field of laser micro-blind holes, and specifically relates to an interlayer interconnection device for HDI boards based on laser micro-blind hole technology. Background Technique

[0002] Laser micro-blind hole technology utilizes the characteristics of high energy and small focus area of the laser, focuses the laser beam below the surface of the workpiece, forms a molten pool at the bottom of the drilled hole, and gradually processes the blind hole by adjusting the laser processing parameters and the moving trajectory of the light beam. A blind hole refers to a hole drilled inside the workpiece, and the hole opening is not drilled through and is not connected to the surface of the workpiece.

[0003] In the actual application of the interlayer interconnection device for HDI boards, if the HDI board fails to be firmly fixed in the predetermined position, then even the slightest external force may cause the HDI board to shift or shake. This unstable condition will not only make it difficult to accurately align the connection interfaces and increase the connection difficulty, but may also cause poor contact, signal attenuation, or even connection failure due to misalignment or excessive gaps during the connection process, seriously affecting the subsequent connection quality and the overall performance of the product. At the same time, since the length of the copper wire is fixed and the interconnection device cannot be adjusted in real time according to the specific position of the HDI board, it makes the precise connection between the copper wire and the HDI board extremely difficult. This inflexibility not only limits the flexibility and efficiency in the production process, but may also have an adverse impact on the connection quality of the circuit, thereby affecting the performance and reliability of the entire product.

Both ends of the bidirectional threaded rod 43 are rotatably connected to the fixed blocks 42. One end of the bidirectional threaded rod 43 penetrates to one side of the fixed block 42 and is fixedly connected with a motor 44. Two second threaded blocks 45 are threadedly connected to the surface of the bidirectional threaded rod 43. The top of the second threaded block 45 is fixedly connected with a second square plate 46. Two connecting blocks 47 are fixedly connected to the top of the second square plate 46. The top of the connecting block 47 penetrates to the outside of the box body 1 and is fixedly connected with the placing plate 32.

[0024] Specifically, two guide rods 5 are fixedly connected to both sides of the support seat 41. A guide block 6 is slidably connected to the surface of the guide rod 5.

[0026] Specifically, an installation seat 7 is sleeved on the surface of the motor 44. Bolts are threadedly connected to both sides of the top of the installation seat 7. The installation seat 7 and the box body 1 are detachably connected by bolts.

The first threaded block 36 drives the pressing plate 33 to move, and the pressing plate 33 drives the slider 9 to move in the inner cavity of the chute 8. As the pressing plate 33 continuously descends, it drives the protective pad 10 to contact the HDI board, thereby fixing the HDI board. Then, by starting the motor 44, the output shaft of the motor 44 drives the bidirectional threaded rod 43 to rotate. When the bidirectional threaded rod 43 rotates, it drives the two second threaded blocks 45 to move relatively. The second threaded block 45 drives the second square plate 46 to move, and the second square plate 46 drives the guide block 6 to slide on the surface of the guide rod 5, thereby supporting the second square plate 46. When the second square plate 46 moves, it drives the connecting block 47 to move, and the connecting block 47 drives the placement plate 32 to move. The placement plate 32 drives the HDI board to move, thereby adjusting the distance between the two HDI boards, facilitating the user to connect the HDI board and the copper wire.
