The sponge cooling layer 5 is provided with a protective cardboard 7 at both ends, and the two sides of the sponge cooling layer 5 are embedded with liquid guide tubes 8 which are parallel to each other. When the substrate 1 of this structure is cushioned on the bottom of the printed circuit board for drilling processing, the sponge cooling layer 5 can be soaked by pre-inputting cooling water through the liquid guide tubes 8 on both sides. After being soaked, the sponge cooling layer 5 will maintain a certain humidity. When the drill bit drills into the lubricating layer 6 to obtain preliminary heat absorption and cooling and then drills into the sponge cooling layer 5, the sponge cooling layer 5 can use its own humidity to absorb heat and cool the drill bit again, so that the sponge cooling layer 5 can achieve a good heat dissipation effect on the drill bit, so as to improve the processing quality, and solve the problem that the existing lubricating pads absorb heat and cool the drill bit through the lubricating layer coated on the surface. There is a problem that the heat dissipation effect is generally poor. A plurality of liquid outlets are provided on the corresponding side of the liquid guide tube 8, and a connecting hose 9 is provided at the front end of the liquid guide tube 8. The liquid guide tube 8 of this structure can evenly immerse the coolant into the interior of the sponge cooling layer 5 through the plurality of liquid outlets, and the connecting hose 9 can conveniently input the coolant into the liquid guide tube 8. A plurality of rubber columns 10 are evenly provided on both sides of the sponge cooling layer 5, and the rubber columns 10 are located at the outer side of the liquid guide tube 8. The upper and lower ends of the rubber columns 10 are respectively bonded and fixed to the corresponding positions of the protective cardboard 7. The rubber columns 10 of this structure can support the liquid guide tube 8 between the two protective cardboards 7 to prevent the liquid guide tube 8 from being squeezed too much during the compression of the sponge cooling layer 5. One side of the substrate 1 is provided with A concave hole 11 is provided with a post 12 extending outward inside the concave hole 11, and a post 15 matching the post 12 is provided on the other side of the substrate 1, an inner post 16 is provided inside the post 15, and a sleeve hole matching the structure of the inner post 16 is provided inside the outer end of the post 12. The substrates 1 of this structure can be connected to each other by extending the post 12 into the inside of the post 15, and the post 12 will simultaneously sleeve the sleeve hole at the outer end on the outside of the inner post 16 when connecting, so that the substrates 1 can be quickly positioned and connected to each other, which is convenient for use. A connector 14 is provided on the inner wall of the inner end of the concave hole 11, and the inner end of the connector 14 can be bonded and fixed on the inner wall of the inner end of the concave hole 11, and a connecting column 13 that movably extends into the connector 14 is provided at the inner end of the post 12.The connection between the connecting column 13 and the clamping column 12 is welded and fixed, and a spring member is sleeved outside the connecting column 13. The clamping column 12 of this structure can drive the connecting column 13 to extend into the inside of the connector 14 and make the spring member move. In this way, the clamping column 12 can be more firmly docked inside the clamping hole 15 under the action of the spring member outside the connecting column 13, thereby improving the stability of the substrates 1 when they are spliced ​​together.

[0018] Working principle: When using the lubricating pad drilling heat dissipation structure, first, when the substrate 1 is padded at a suitable position at the bottom of the printed circuit board to cooperate with the drilling process, the sponge cooling layer 5 can pre-input an appropriate amount of cooling water into the two liquid guide tubes 8 through the connecting hose 9, and the cooling water flowing into the liquid guide tube 8 will flow out from a number of liquid outlets to evenly soak the sponge cooling layer 5. After being soaked, the sponge cooling layer 5 will maintain a certain humidity. When the drill bit drills into the interior of the lubricating layer 6 to obtain preliminary heat absorption and cooling, and then passes through the protective cardboard 7 to drill into the sponge cooling layer 5, the sponge cooling layer 5 will effectively absorb heat and cool the drill bit again due to its own humidity, until the drill bit drills into the buffer layer 4 and the protective layer 3 in turn. When two substrates 1 need to be spliced ​​together for use, one of the substrates 1 only needs to align the clamping column 12 with the clamping hole 15 of the other substrate 1 and extend it into the inside. When the clamping column 12 is extended, the sleeve hole at the outer end will be synchronously sleeved on the outside of the inner column 16, and after the clamping column 12 is subjected to the resistance pressure, it will drive the connecting column 13 to extend into the inside of the connecting head 14 to make the spring part move, so that the clamping column 12 will be more firmly docked in the clamping hole 15 under the action of the spring part outside the connecting column 13, and the two substrates 1 will be more firmly spliced ​​together, thereby completing a series of tasks.
