[0070] Example 1

[0071] Reference Figure 1 and Figure 2 , which is the first embodiment of the present invention, and provides a method for optimizing power supply of a copper wire system, comprising the following steps:

[0072] S1. Establish a simulation model of an intelligent copper bonding wire system, obtain virtual parameters based on the simulation model of the intelligent copper bonding wire system, and optimize the virtual parameters.

[0073] The steps to establish the intelligent copper bonding wire system simulation model include:

[0074] Collect historical data on bonding equipment power usage and process parameters;

[0075] Analyze the correlation between power usage data and process parameters, and establish a simulation model for the intelligent copper bonding wire system based on the correlation;

[0076] The power usage data includes power supply power and bonding temperature, and the process parameters include setting the speed of the bonding copper wire, the tension of the bonding copper wire and the diameter of the bonding copper wire.

[0077] Collect historical data from different batches of bonding processes, especially data on power supply power and bonding temperature, from production run records, including:

[0078] Power supply power (P): recorded in watts (W);

[0079] Bonding temperature (T): recorded in degrees Celsius (°C);

[0080] Bonding wire speed (V): in millimeters per second (mm / s);

[0081] Bonding copper wire tension (Tension): in grams (g);

[0082] Bonding copper wire diameter (D): in millimeters (mm).

[0083] The steps for optimizing virtual parameters include:

[0084] Construct the objective function of power efficiency, which is specifically expressed as:

[0085]

[0086] In each iteration, the objective function f(x) is calculated at the current parameter point x k The gradient function Δf(x) is specifically expressed as:

[0087]

[0088] Update the parameters to the new position:

[0089] x k+1 =x k -αΔf(x k );

[0090] In the formula, α represents the learning rate, k represents the current number of iterations, and each partial derivative It means that the function f is applied to a single variable x while other variables are fixed. n The rate of change of

[0091] After each iteration, check whether the optimization has converged and set a convergence threshold. When the change in the objective function is less than the convergence threshold, the optimization process ends. The convergence condition is expressed as:

[0092] |f(x k+1 )-f(x k )|≤ε;

[0093] In the formula, ε represents the convergence threshold.

[0094] S2. Apply the optimized virtual parameters to the actual bonding device, and collect the actual power and bonding effect of the bonding device.

[0095] The steps for judging the bonding effect include:

[0096] Obtain the actual specification of the copper wire to be welded, find the copper wire with the same specification from the database, and load the historical information corresponding to the copper wire;

[0097] Determine whether the result of the historical information is qualified. If the result is qualified, perform a secondary judgment. If the result is unqualified, find the copper wire of the same specification from the database again until a copper wire with a qualified result is found.

[0098] When no qualified copper wire is found, the copper wire of the specification is registered and the remaining information is input into the database.

[0099] In this embodiment, the actual welding copper wire specifications are:

[0100] Copper wire diameter: 0.025mm;

[0101] Bonding temperature: 150℃;

[0102] Bonding speed: 2.8mm / s;

[0103] Tension: 53g;

[0104] Use database query statements to retrieve records that match the current actual welding copper wire specifications from the historical data table, and the following historical information records are obtained in the database:

[0105] Table 1: Historical information of the database

[0106]

[0107]

[0108] First, check that the first record is 1, and the welding result is "qualified", so a secondary judgment is performed. When checking that the first record is 2, the welding result is "unqualified", so it is necessary to search again until a record with a welding result of "qualified" is found.

[0109] The steps of secondary judgment include:

[0110] Obtain all classified data in the historical information, and compare all classified data in turn;

[0111] Among them, an error threshold is set for a single classification data. When the difference between the classification data of the historical information and the classification data of the actual information is greater than the error threshold, the bonding effect is judged to be unqualified, otherwise, the bonding effect is judged to be qualified;

[0112] In this embodiment, the classified data for comparison include copper wire diameter, bonding temperature, bonding speed and tension, and an error threshold is set for all classified data, such as the error threshold of copper wire diameter is 0.005 mm, the threshold error of bonding temperature is 5°C, the threshold error of bonding speed is 0.3 mm / s, and the threshold error of tension is 5. The classifications are compared to determine whether the actual welding parameters and the parameters of the historical data are within the error threshold.

[0113] When the bonding effect is judged to be qualified, all the classification data of this time are uploaded to the database and merged with the classification data in the historical information. The specific fusion method is expressed as follows:

[0114] L i =L i,old κ+L i,new ·λ;

[0115] Where, L i Represents a certain classification data after fusion, L i,old Represents a certain classification data in the historical data, L i,new It represents a certain classification data of this time, κ and λ are both weight values, and κ<λ, κ+λ=1;

[0116] Taking tension as an example, during fusion, the tension in the historical data is 50g, the actual tension is 53g, and the weight value κ is 0.4 and the weight value λ is 0.6. Therefore, they are loaded into the calculation formula and the tension after fusion is 51.8g.

[0117] S3. When the bonding effect is qualified, the actual power is optimized and a power adjustment plan is given.

[0118] The steps to optimize the actual power include:

[0119] Set the optimal value D of the bonding temperature, and establish a temperature range [DS, D+S] before and after the optimal value D, and divide the range into three parts;

[0120] Among them, the three intervals are: excellent temperature interval, medium temperature interval and poor temperature interval;

[0121] When the actual value W of the bonding temperature is within the optimal temperature range, the power supply power is not adjusted;

[0122] When the actual value W of the bonding temperature is in the intermediate temperature range, the power supply is adjusted at the primary level;

[0123] When the actual value W of the bonding temperature is in the differential temperature range, the power supply is adjusted in an advanced manner;

[0124] The optimal temperature range is [Dq, D+q];

[0125] The intermediate temperature range is [Dp, Dq] and [D+q, D+p];

[0126] The differential temperature intervals are [DS, Dp] and [D+p, D+S].

[0127] like Figure 2 As shown, by setting different interval values ​​q, p and S, different temperature intervals are set, and the power supply power is adjusted according to different intervals.

[0128] The steps of primary adjustment include:

[0129] When the actual value of the bonding temperature W is in the intermediate temperature range [Dp, Dq], the adjustment formula for the power supply is expressed as:

[0130] V new =V old +(DW)·δ;

[0131] Where V new Expressed as the adjusted power supply power, V old It represents the power before adjustment, D represents the optimal value of bonding temperature, W represents the actual value of bonding temperature, and δ represents the correlation coefficient;

[0132] For example, in this embodiment, the optimal value D of the bonding temperature is 145°C, wherein the intermediate temperature range [Dp, Dq] is [135, 140], and the actual value W of the bonding temperature is 138°C, so the power supply power needs to be adjusted, and a new power supply power is obtained by adjusting the formula, thereby realizing the adjustment of the power supply power;

[0133] This method can adjust the actual value of the bonding temperature to an optimal temperature range by slightly adjusting the power supply according to the change of the actual value of the bonding temperature, thereby ensuring the stability of subsequent operations.

[0134] When the actual value W of the bonding temperature is in the intermediate temperature range [D+q,D+p], the adjustment formula for the power supply is expressed as:

[0135] V new =V old -(WD)·δ;

[0136] The steps of the advanced adjustment include:

[0137] An optimal value D of the bonding temperature is obtained, and a power supply power corresponding to the optimal value D of the bonding temperature is obtained based on a database, and the corresponding power supply power in the database is used as the adjusted power supply power.

[0138] S4. If the bonding effect is unqualified, stop the operation and determine the cause of the abnormality.

[0139] In summary, the intelligent copper bonding wire system can significantly improve energy efficiency through power optimization. In the field of semiconductor packaging and microelectronics manufacturing, traditional bonding processes often rely on fixed power settings, which cannot adapt to different working conditions and material properties, resulting in energy loss and unstable bonding quality. By optimizing power in real time, this method reduces unnecessary energy consumption, reduces production costs, and improves bonding quality, which is of great significance for improving the energy efficiency and economic benefits of semiconductor packaging.
