[0032] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] Figure 1 This is a flow chart of a method for adding PCB solution provided in the first embodiment of the present invention. This embodiment is applicable to the case of adding solution during the PCB manufacturing process. The method can be performed by a PCB solution adding device. The PCB solution adding device can be implemented in the form of hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the PCB solution adding method includes:

[0035] S101, determining a consumption type of the medicine to be added to the reaction container, where the consumption type includes at least one of a reaction type, a carry-out type, a volatilization type, and a decomposition type.

[0036] This embodiment can be used to add chemicals during the PCB production process. The reaction container can be a container for injecting chemicals for chemical reactions in each production process in each production line. The production line can include tinning lines, gold immersion lines, sandblasting lines, etc. The production processes can include degreasing, micro-etching, pickling, pre-dip, activation, post-dip and other processes. The reaction container can be a reaction cylinder for each process.

[0037] The potion can be a chemical potion injected into the reaction vessel for the PCB production process. Different production lines and processes have different potions. The consumption type of the potion can refer to the type of potion consumed in the reaction vessel. The consumption type of a potion in the reaction vessel can be one or more. Among them, the reaction type consumption can refer to the potion consumption through chemical reaction, the carry-out type consumption can refer to the potion consumption caused by the PCB being taken out of the reaction vessel in the form of residue on the PCB, the volatilization type can refer to the natural volatilization consumption of the potion in the reaction vessel at different temperatures, and the decomposition type can refer to the potion consumption in the reaction vessel due to decomposition, such as NaPS (sodium persulfate), H2O2 (hydrogen peroxide), etc., which belong to the decomposition type consumption potion.

[0038] For each process of different lines, you can set the consumption type of the potion. When you need to add potion to the process, read the preset consumption type of the potion.

[0039] S102, obtaining PCB data of the PCB produced in the reaction container.

[0040] The PCB data may be the board area of ​​the produced PCB, the metal area of ​​the metal to be reacted, and the thickness of the metal to be reacted, wherein the board area may be the area of ​​the PCB, the metal to be reacted may be the metal on the PCB that needs to be removed or deposited on the PCB through a chemical reaction of a solution, for example, the metal to be reacted may be copper, gold, silver, etc., the metal area may be the surface area of ​​the metal to be reacted removed or deposited on the PCB, for example, it may be the copper area, and the metal thickness may be the thickness of the metal to be reacted removed or deposited on the PCB, for example, it may be the thickness of the etched copper.

[0041] The board area of ​​the PCB, the metal area of ​​the metal to be reacted, and the metal thickness to be reacted in the PCB data can be determined by the design data or process data of the PCB. For example, the board area of ​​the PCB, the metal area of ​​the metal to be reacted, and the metal thickness to be reacted in a certain process can be found from the process data of the PCB through the PCB code (such as a QR code) and the corresponding process.

[0042] S103. Calculate the metal unit area consumption and the board unit area consumption of the solution based on the consumption type and PCB data, wherein the metal unit area consumption is the unit area consumption of the reaction type, and the board unit area consumption is the unit area consumption of at least one of the carry-out type, the volatilization type, and the decomposition type.

[0043] For example, if a potion is used for chemical reactions and has a volatile property, the consumption types of the potion may include reaction-type consumption, volatilization-type consumption, and carry-out-type consumption. The metal unit area consumption may be the potion consumption caused by the reaction between the metal to be reacted (such as copper) and the potion in a unit area (such as 1 square meter) on the PCB. The board unit area consumption may be the potion consumption caused by at least one of the carry-out type, volatilization type, and decomposition type consumption when producing a unit area of ​​PCB.

[0044] For different consumption types, calculation rules can be set in advance, and the unit consumption area is calculated based on the calculation rules of various consumption types. For example, the calculation rule for the unit area consumption of the reaction type can be the chemical reaction equation of the potion, and the calculation rule for the unit area consumption of the carry-out type, the volatile type and the decomposition type can be a statistical analysis calculation based on historical consumption data. This embodiment can pre-configure the calculation rules for the reaction type, carry-out type, volatile type and decomposition type potions when producing different PCBs in each process, and calculate the metal unit area consumption of the potion and the unit area consumption of the board through the configured calculation rules.

[0045] S104. During the PCB production process, the cumulative production quantity of the PCB in the reaction container is counted, and the cumulative metal area and the cumulative board area are calculated based on the production quantity and the PCB data.

[0046] PCB data includes the metal area of ​​the metal to be reacted in a PCB and the board area of ​​the PCB. Each time a PCB is produced, the metal area and the board area are accumulated to obtain the current production accumulated metal area and accumulated board area.

[0047] S105. Calculate the total consumption of the liquid medicine according to the metal consumption per unit area, the plate consumption per unit area, the cumulative metal area and the cumulative plate area.

[0048] Specifically, the total metal consumption is obtained by multiplying the metal consumption per unit area by the cumulative metal area, the total plate consumption is obtained by multiplying the plate consumption per unit area by the cumulative plate area, and the total potion consumption is obtained by calculating the sum of the total metal consumption and the total plate consumption.

[0049] S106: When the total consumption of the medicine reaches a preset threshold, add medicine to the reaction container.

[0050] In this embodiment, the control point of the medicine can be set in advance and the initial concentration of the medicine in the reaction container can be measured before the production line is started every day. The control point can be the desired target medicine concentration, which is the ideal medicine concentration in the production process. The upper and lower concentrations can be set through the control point, and the difference between the initial concentration and the lower concentration can be calculated, and the product of the difference and the volume of the reaction container can be calculated to obtain the available amount of medicine, which is the preset threshold. In one example, the difference between the upper and lower concentrations can be calculated, and the difference and the volume of the reaction container can be calculated to obtain the amount of medicine to be added, that is, the amount of medicine that needs to be added when the medicine is consumed to reach the lower concentration.

[0051] In the embodiment of the present invention, by determining that the medicine is at least one of the consumption types of reaction type, carry-out type, volatilization type and decomposition type, the metal unit area consumption and the board unit area consumption of the medicine are calculated based on the consumption type and PCB data. In the PCB production process, the cumulative production quantity of PCBs in the reaction container is further counted, and the cumulative metal area and the cumulative board area are calculated according to the production quantity and the PCB data. The total consumption of the medicine is calculated according to the metal unit area consumption, the board unit area consumption, the cumulative metal area and the cumulative board area. When the total consumption of the medicine reaches a preset threshold, the medicine is added. On the one hand, when the total consumption of the medicine reaches the preset threshold, the medicine is added, so that the medicine can be added in time to avoid hysteresis. On the other hand, the metal unit area consumption and the board unit area consumption are calculated according to multiple types of medicine consumption, so as to respectively calculate the consumption of the medicine by the metal reaction and the carry-out type, volatilization type and decomposition type of the medicine consumption of the non-metallic reaction in the process. The medicine consumption is calculated from a finer granularity, and the calculated total consumption of the medicine is more accurate. The medicine can be added at an accurate time to ensure that there is enough medicine for production, thereby improving the stability of product quality.

[0052] Embodiment 2

[0053] Figure 2 This is a flow chart of a PCB solution adding method provided in the second embodiment of the present invention. The embodiment of the present invention is optimized on the basis of the above-mentioned first embodiment. Figure 2 As shown, the PCB solution adding method includes:

[0054] S201, determining a consumption type of the medicine to be added to the reaction container, where the consumption type includes at least one of a reaction type, a carry-out type, a volatilization type, and a decomposition type.

[0055] In this embodiment, the consumption type of a potion in the reaction container can be one or more types, wherein the consumption of the reaction type may refer to the consumption of the potion through chemical reactions, the consumption of the carry-out type may refer to the consumption of the potion due to the PCB being taken out of the reaction container and left on the PCB, the volatilization type may refer to the natural volatilization of the potion in the reaction container at different temperatures, and the decomposition type may refer to the consumption of the potion in the reaction container due to decomposition. For each process of different lines, the consumption type of the potion can be set, and when the potion needs to be added to the process, the preset consumption type of the potion is read.

[0056] S202, obtaining PCB data of the PCB produced in the reaction container.

[0057] The PCB data may be the board area of ​​the produced PCB, the metal area of ​​the metal to be reacted, and the thickness of the metal to be reacted. The PCB data may be determined by the design data of the PCB.

[0058] S203, determining the calculation rules for the consumption of medicines of different consumption types.

[0059] The calculation rules may be calculation algorithms for the unit area consumption of different types of potions. The calculation rules may be based on the chemical reaction equations of the potions, statistical analysis algorithms for historical consumption data, etc. The calculation rules for different potions in different production processes and different consumption types may be pre-configured.

[0060] S204, calculating the metal unit area consumption and the board unit area consumption based on the calculation rules of the medicine consumption of different consumption types and the PCB data.

[0061] In one embodiment, when the consumption type is reactive type, the chemical reaction equation of the liquid medicine in the reaction container and the metal to be reacted on the PCB is determined as the liquid medicine consumption calculation rule, so as to calculate the metal unit area consumption a of the reactive type through the chemical reaction equation, the density of the metal to be reacted and the reaction thickness.

[0062] Specifically, the molar mass ratio of the molar mass of the chemical solution to the molar mass of the metal to be reacted can be calculated by first using the molar mass of the chemical solution and the molar mass of the metal to be reacted in the chemical reaction equation, and the product of a unit area, the density of the metal to be reacted, and the reaction thickness can be calculated to obtain the mass of the metal to be reacted per unit area, and the product of the mass and the molar mass ratio can be calculated to obtain the metal unit area consumption a of the chemical solution in the reaction type.

[0063] When the consumption type is at least one of the carry-out type, the volatilization type, and the decomposition type, the calculation rule of the liquid medicine consumption is to determine the consumption per unit area of ​​the board based on the statistical analysis of the historical consumption data of the liquid medicine, then the historical consumption data of the liquid medicine can be obtained, such as the liquid medicine consumption of each production cycle in multiple production cycles, the metal area of ​​the metal to be reacted, and the board area of ​​the PCB, etc. are obtained as the historical consumption data of the liquid medicine, and the unit area consumption of the carry-out type, the volatilization type, and the decomposition type boards are calculated based on the historical consumption data of the liquid medicine. Specifically, the sum of the liquid medicine consumption of multiple production cycles can be calculated to obtain the total liquid medicine consumption D of multiple production cycles, the sum of the metal areas of multiple production cycles can be calculated to obtain the total metal area E, and the sum of the PCB areas of multiple production cycles can be calculated to obtain the total PCB area F, and the unit area consumption b of the carry-out type, the volatilization type, and the decomposition type boards are calculated by the following formula:

[0064] b=(Da×E) / F;

[0065] Where a is the consumption of reactive metal per unit area.

[0066] Taking the etching of copper (Cu) on PCB by H2SO4 (sulfuric acid) in the micro-etching tank of immersion tin wire as an example, H2SO4 needs to react with Cu. At the same time, after the PCB is taken out of the micro-etching tank and transferred to the next process, H2SO4 will remain on the PCB, resulting in carry-out consumption.

[0067] For calculating the consumption of Cu per unit area a by the H2SO4 reaction type, the reaction equation of H2SO4 in the micro-etching cylinder is as follows:

[0068] Cu+H2SO4+H2O2=CuSO4+2H2O;

[0069] In the above reaction equation, the molar mass of Cu is 64, the molar mass of H2SO4 is 98, and the molar mass ratio of H2SO4 to Cu is 98 / 64. 2 (square meters) As an example, the density of Cu is 8.9 g / cm 3 , micro-etching thickness is 1.2μm, micro-etching 1m 2 The mass of H2SO4 required for copper with a thickness of 1.2μm is:

[0070] H2SO4=1×10 4 ×1.2×10 -4 ×8.9×(98÷64)=16.34g (grams).

[0071] That is, the consumption of Cu per unit area by H2SO4 reaction type is a=16.34g, that is, per production of micro-etching 1m 2 The amount of H2SO4 consumed in the reaction of copper with a thickness of 1.2 μm is 16.34 g.

[0072] For calculating the consumption per unit area of ​​H2SO4, the historical H2SO4 concentration A before production can be calculated. i , concentration after production B i , copper production area E i , plate area F i , calculate the consumption D of H2SO4 on day i i =(A i -B i )×C, C is the volume of the micro-etching cylinder.

[0073] The total consumption of H2SO4 in the past 10 days D=D1+D2+……D 10 =11883.5g;

[0074] The copper production area of ​​H2SO4 in the past 10 days is E=E1+E2+……E 10 =300.53m 2 ;

[0075] The H2SO4 production area in the past 10 days is F = F1 + F2 + ... F 10 =426.6m 2 ;

[0076] Substituting the second unit area consumption b, the consumption of H2SO4 carried out is as follows:

[0077] b=(Da×E) / F=(11883.5-16.34×300.53) / 426.6=16.35gm 2 , that is, every production of 1m 2 A specific model of PCB, 1m 2 The PCB will bring out 16.35g of H2SO4 consumption.

[0078] The unit area consumption of the decomposition type and volatilization type boards can also refer to the carry-out type, which will not be described in detail here. The unit area consumption of the volatilization type boards can also be determined by statistically analyzing the volatilization amount at different temperatures.

[0079] S205. During the PCB production process, the cumulative production quantity of the PCB in the reaction container is counted, and the cumulative metal area and the cumulative board area are calculated based on the production quantity and the PCB data.

[0080] Specifically, the PCB data includes the metal area and board area of ​​the metal to be reacted (such as copper) on the PCB. During the production process, the PCBs put into the reaction container can be counted by a timer. Every time a PCB is counted, the accumulated metal area and the accumulated board area are calculated according to the calculated production quantity. For example, the product of the production quantity and the metal area of ​​a single PCB is the accumulated metal area, and the product of the production quantity and the board area of ​​a single PCB is the accumulated board area.

[0081] S206. Calculate the product of the metal consumption per unit area and the cumulative metal area to obtain the total metal consumption of the potion.

[0082] Since the metal consumption per unit area is the consumption of potion required for the reaction of a unit area of ​​the metal to be reacted (such as copper), the product of the cumulative metal area and the metal consumption per unit area can be calculated to obtain the amount of potion required for the reaction of the cumulative metal area with the potion, that is, the total metal consumption of the potion.

[0083] S207, calculating the product of the board consumption per unit area and the cumulative board area to obtain the total board consumption of the liquid medicine.

[0084] Since the consumption per unit area of ​​the board is the consumption of the medicine caused by the non-metallic reaction (at least one of carry-out, volatilization, and decomposition) of a unit area of ​​the PCB board, the product of the cumulative board area and the consumption per unit area of ​​the board can be calculated to obtain the consumption of the medicine caused by the cumulative board area, that is, the total consumption of the medicine on the board.

[0085] S208. Calculate the sum of the total metal consumption and the total plate consumption to obtain the total potion consumption.

[0086] In this embodiment, during the PCB production process, the chemical solution is continuously consumed as the PCBs are put into use. The total chemical solution consumption includes the total metal consumption of the chemical solution for metal reactions and the total board consumption caused by non-metallic reactions (at least one of carry-out, volatilization, and decomposition), that is, the sum of the total metal consumption and the total board consumption.

[0087] S209: When the total consumption of the medicine reaches a preset threshold, add medicine to the reaction container.

[0088] Taking the control range of the potion concentration as 80+ / -10 as an example, it is expected that when the concentration drops to the lower limit concentration of 75, potion is added to the upper limit concentration of 85. If the initial concentration of the potion is 80 (usually adjusted to the median of the control range when opening the line), the preset threshold is T=(80-75)C, where C is the volume of the reaction container. When the total consumption of the potion reaches T, potion is added, and the amount added is the difference between the volume C of the reaction container and the expected value of 85 and 75.

[0089] In this embodiment, the consumption type of the medicine to be added is divided into a reaction type, a carry-out type, a volatile type, and a decomposition type. After determining the consumption type of the medicine to be added, a calculation rule for the consumption of the medicine of different consumption types is determined. The metal unit area consumption and the board unit area consumption are calculated based on the calculation rule for the consumption of the medicine of different consumption types and the PCB data. Further, in the PCB production process, the cumulative production quantity of the PCB in the reaction container is counted, and the cumulative metal area and the cumulative board area are calculated according to the production quantity and the PCB data. The medicine consumption is calculated according to the metal unit area consumption, the board unit area consumption, the cumulative metal area, and the cumulative board area. The total water consumption, when the total consumption of the medicine reaches the preset threshold, the medicine is added. On the one hand, the medicine can be added in time to avoid lag, and on the other hand, the metal unit area consumption and the plate unit area consumption are calculated through various types of medicine consumption, so as to calculate the consumption of medicine by metal reaction and the carry-out type, volatilization type and decomposition type of medicine consumption of non-metallic reaction in the process respectively. The medicine consumption is calculated from a finer granularity, and the calculated total consumption of medicine is more accurate, so that the medicine can be added at the right time to ensure that there is enough medicine for production, thereby improving the stability of product quality.
