[0042] The following will be combined with the embodiments to clearly and completely describe the concept of the present invention and the technical effects produced, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0043] In the description of the present invention, if it involves a description of orientation, for example, the orientation or position relationship indicated by "upper", "lower", "front", "back", "left", "right", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. If a feature is referred to as being "set", "fixed", "connected", or "installed" on another feature, it can be directly set, fixed, or connected to the other feature, or it can be indirectly set, fixed, connected, or installed on the other feature.

If "first" or "second" is involved, it should be understood as being used to distinguish technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0045] During the production of circuit boards, the copper layer on the circuit boards needs to be drilled with a drill bit. However, the service life of the drill bit is a unified value given after the test board processing evaluation in the verification phase. In actual use, the degree of wear on the drill bit varies with the processing of different circuit boards, so it is impossible to accurately judge the remaining service life of the drill bit during use. Therefore, the current calculation method for the drill bit life is not accurate, and it is impossible to accurately process the circuit board based on the drill bit service life.

[0046] Based on this, the present application discloses a drill bit life calculation method, which can accurately calculate the drill bit's life for drilling holes in different circuit boards, improve the accuracy of the drill bit life calculation, and facilitate stable processing of circuit boards based on the drill bit life.

[0047] Reference Figure 1 The embodiment of the present invention discloses a method for calculating the life of a drill bit, comprising:

[0048] S100, obtaining characteristic parameters of a target circuit board that a drill needs to drill;

[0049] S200, receiving a preset life influence parameter and a preset maximum influence value of the characteristic parameter on the life of the drill bit;

[0050] S300, determining the service life of the drill bit according to the characteristic parameters, the life influencing parameters, the preset calculation formula and the maximum value of the influencing value.

[0051] In step S100, since the characteristics of the circuit board will affect the life of the drill bit, it is necessary to calculate the service life of the drill bit according to the characteristic parameters of the target circuit board. The target circuit board is designed to be multi-layered during product design, and different layers require drill bits of different diameters for drilling, so it is necessary to obtain the thickness of the number of copper layers and the material thickness of the material type that drill bits of different diameters need to pass through to obtain characteristic parameters.

[0052] In step S200, the preset life impact parameter and the preset maximum impact value input by the user in the interface are received, wherein the preset maximum impact value is determined according to the product requirements of the target circuit board, that is, according to the product's acceptance of the impact program of each impact factor.

[0053] In step S300, the preset calculation formula calculates the impact value of the target circuit board according to the characteristic parameters, the preset life impact parameters, and the service life, and the impact value is also the specific value of the impact factor. Therefore, the service life of the drill bit can be inferred based on the preset maximum impact value.

[0054] By executing steps S100 to S300, the obtained characteristic parameters of the target circuit board, the preset life influencing parameters, and the preset maximum value of influence are substituted into the preset calculation formula to obtain the service life of the drill bit. Therefore, the service life calculation of the drill bit is more accurate.

[0055] In some embodiments, the characteristic parameters include: the thickness of the copper layer through which the drill bit passes through the plurality of copper layers, and the material thickness of the dielectric material of the target circuit board.

[0056] Since drill bits of different diameters are needed to drill holes in the target circuit board, and the target circuit board is designed with multiple copper layers, the thickness of the copper layer through which the drill passes needs to be calculated. Since the dielectric material of the target circuit board also has a certain influence on the life of the drill bit, obtaining the copper layer thickness and material thickness can accurately calculate the service life of the drill bit.

[0057] For example, when designing a product, the target circuit board has a total of N copper layers, and the thickness of each copper layer is Aum, and the thickness of the dielectric material is B. Among them, the target circuit board requires the first drill to pass through the copper layer of layer n, and the copper layer thickness of the first drill passing through the copper layer of layer n is (A*n)um. The second drill passes through the copper layer of layer m, and the copper layer thickness of the second drill passing through the copper layer of layer m is (A*m)um.

[0058] In some embodiments, the preset life-influencing parameters include: influence rate, life-influencing thickness and drilling times. The influence rate includes blade wear rate, diameter change rate, etc., the life-influencing thickness is the influence of copper or dielectric material on the copper layer thickness of the drill bit drilling, and the drilling times is the influence of copper or dielectric material on the drilling times of the drill bit.

[0059] Among them, the preset life influencing parameters include: the influencing parameters of copper on the drill bit life and the influencing parameters of dielectric materials on the drill bit life. Therefore, the influencing rate includes: the first influencing rate of copper on the drill bit life and the second influencing rate of dielectric materials on the drill bit life; the life influencing thickness includes: the first influencing thickness of copper on the drill bit life and the second influencing thickness of dielectric materials on the drill bit life; the drilling times include: the first drilling times of copper on the drill bit life and the second drilling times of copper on the drill bit life.

[0060] For example, the first influence rate, the first influence thickness and the first drilling number are obtained as X1 / Y1 / Z1, and the second influence rate, the second influence thickness and the second drilling number are obtained as X2 / Y2 / Z2.

[0061] Since the influencing parameters of copper on the drill bit life are different from those of the dielectric material, the first influencing rate, the first influencing thickness and the first drilling number of copper on the drill bit life are obtained, and then the second influencing rate, the second influencing thickness and the second drilling number of the dielectric material on the drill bit life are obtained.

[0062] In some embodiments, reference Figure 2 , step S300 includes but is not limited to step S310 and step S320.

[0063] S310, according to the life impact rate, copper layer thickness, life impact thickness, material thickness into the preset calculation formula to obtain the drill bit impact relationship;

[0064] S320, determining the service life of the drill bit according to the drill bit influence relationship, the number of drilling times and the maximum influence value.

[0065] The preset calculation formula is to calculate the product failure rate based on the copper layer thickness, dielectric material thickness and service life, and the preset maximum impact value is also the maximum failure rate. Therefore, the service life of the drill bit can be determined by the relationship between the maximum impact value, the number of drillings and the drill bit impact, so as to accurately calculate the service life of the drill bit.

[0066] In some embodiments, reference Figure 3 , step S320 includes but is not limited to step S321 and step S322.

[0067] S321, determining an initial drilling rate according to a drill bit influence relationship and an influence maximum value;

[0068] S322, taking an integer of the initial drilling rate to obtain a target drilling rate;

[0069] S323, obtaining the service life of the drill bit according to the target drilling rate and the number of drilling times.

[0070] Among them, the life impact rate, copper layer thickness, life impact thickness, and material thickness are substituted into the preset calculation formula to obtain the drill bit impact relationship, and the drill bit impact relationship is a relationship with unknowns, and the unknown is the initial drilling rate. Since the drill bit impact relationship is also used to calculate the unqualified rate of the target circuit board, and since there are certain product requirements for the unqualified target circuit board, that is, the preset maximum impact value, the initial drilling rate is obtained according to the maximum impact value and the preset impact relationship, and the initial drilling rate is integerized to obtain the target drilling rate, and then the target drilling rate and the number of drillings are multiplied to obtain the service life of the drill bit, and the service life of the drill bit is also the number of drillings that can be completed.

[0071] Specifically, the preset calculation formula is P=X1*(A*n / Y1)*h+X2*(B / Y2)*h; where P is the failure rate, h is the initial drilling rate, A is the copper layer thickness, n is the number of copper layers that the drill needs to pass through, B is the thickness of the dielectric material, X1 is the first impact rate, X2 is the second impact rate, Y1 is the first impact thickness, and Y2 is the second impact thickness. If the preset maximum impact value is Q, then Q>X1*(A*n / Y1)*h+X2*(B / Y2)*h, then h is calculated, and then h is rounded and multiplied by the number of drilling times to obtain the service life of the drill bit, that is, the target number of drilling times of the drill bit.

[0072] For example, if X1 / Y1 / Z1=0.1% / 100um / 100hit, X2 / Y2 / Z2 is 0.06% / 100um / 100hit, if the diameter of the drill is 0.2mm, the thickness of the copper layer to be penetrated is 105um, the material thickness of the dielectric material is 1200um, and the maximum impact rate is 30%. Therefore, the initial drilling rate is: 0.3>0.1%*(105÷100)*h+0.06%*(1200÷100)*h, so h<36.36, rounded to h=36, 36*100=3600hit, then the service life of the drill is set to 3600. If the diameter of the drill is 0.3um, the thickness of the copper layer to be penetrated is 210um, the material thickness of the dielectric material is 1200um, and the maximum impact rate is 35%. The initial drilling rate of the drill bit is: 0.35>0.1%*(210÷100)*h+0.06%*(1200÷100)*h, h<42.42, rounded to h=42, 42*100=4200hit, then the service life of the drill bit is 4200.

[0073] In some embodiments, reference Figure 4 The drill bit life calculation method also includes step S400.

[0074] S400: Store the service life of the drill bit in a parameter file.

[0075] By storing the service life of the drill bit in a parameter file, when drill bits of different diameters are needed for product processing, the service life of the drill bit can be directly obtained from the parameter file, so that the target circuit board can be processed according to the drill bits of different diameters. When the drill bit is about to be damaged, it can be replaced in time, thereby improving the qualified rate of target circuit board production.

[0076] Reference Figure 5 In addition, the embodiment of the present invention further discloses a circuit board processing method, including:

[0077] S500, obtaining the service life of drill bits with different diameters by using the drill bit life calculation method as described above;

[0078] S600: Process the target circuit board accordingly according to the service life of drill bits with different diameters.

[0079] Since the target circuit board needs to drill holes of different sizes during processing, drill bits of different sizes are required. Therefore, the above drill bit life calculation method is used to obtain the service life of drill bits of different diameters, and then the target circuit board is processed according to the service life of drill bits of different diameters, so that corresponding processing can be performed or the drill bit can be replaced in time according to the service life of the drill bit, thereby ensuring the qualified rate of the target circuit board production.

[0080] Reference below Figures 1 to 5 The drill bit service life calculation method and circuit board processing method according to the embodiment of the present invention are described in detail with a specific embodiment. It is worth noting that the following description is only an exemplary description and is not a specific limitation of the invention.

[0081] Obtain the thickness of the copper layer through which the drill passes, and the material thickness of the dielectric material of the target circuit board; receive the first influence rate, first influence thickness and first drilling number of copper on the life of the drill as X1 / Y1 / Z1, and the second influence rate, second influence thickness and second drilling number of the dielectric material on the life of the drill as X2 / Y2 / Z2. The preset calculation formula is P = X1*(A*n / Y1)*h+X2*(B / Y2)*h; the preset maximum influence value is Q, then Q>X1*(A*n / Y1)*h+X2*(B / Y2)*h, then calculate the initial drilling rate h, then round the initial drilling rate h and multiply it by the drilling number to obtain the service life of the drill bit, that is, the target drilling number of the drill bit. Finally, store the service life of the drill bit in the reference file. When it is necessary to use drill bits of different diameters for product processing, the service life of the drill bit can be directly obtained from the parameter file to process the target circuit board according to drill bits of different diameters. Therefore, the drill bit is processed according to its service life, and can be replaced in time when the drill bit is about to be damaged, thereby improving the qualified rate of target circuit board production.

[0082] In addition, refer to Figure 6 The embodiment of the present invention further discloses a drill bit life calculation device, comprising:

[0085] The calculation module 300 is used to determine the service life of the drill bit according to the characteristic parameters, the life influencing parameters, the preset calculation formula and the maximum value of the influence.

[0086] Substituting the acquired characteristic parameters of the target circuit board, the preset life influencing parameters, and the preset maximum value of the influencing factor into the preset calculation formula, the service life of the drill bit is obtained. Therefore, the service life of the drill bit obtained by the preset calculation method is more accurate.
