At present, the traditional Tenging subtractive process can no longer meet the fine requirements of HDI boards, especially under the premise that the IC packaging substrate has increasingly smaller requirements for line width and line spacing, and the full additive process is mostly used for processing: inner layer circuit board AOI → super coarsening → ABF film pressing / leveling / baking → Xray target forming positioning holes → trimming waste → laser hole forming → Plasma hole forming slag removal → Desmear hole forming slag removal → copper deposition.

[0044] In one of the embodiments, the obtaining of the dielectric layer pressing state parameters of the high-density interconnected circuit board includes: obtaining the dielectric layer pressing temperature of the high-density interconnected circuit board. In this embodiment, the dielectric layer pressing state parameters are the current in-board dielectric layer pressing state of the high-density interconnected circuit board, that is, the dielectric layer pressing state parameters are the dielectric layer pressing process data under the current pressing process of the high-density interconnected circuit board, that is, the dielectric layer pressing state parameters correspond to the dielectric layer pressing operation state of the high-density interconnected circuit board.

[0047] In another embodiment, when the medium pressing temperature difference does not match the preset temperature difference, a medium pressing warning start signal is sent to the circuit board pressing host computer to stop the board edge pressing of the high-density interconnected circuit board, thereby avoiding excessive glue flow on the board edge due to excessive pressing of the high-density interconnected circuit board, and also avoiding the situation where the thickness requirement of the medium layer after pressing is not met.
[0048] In one of the embodiments, the obtaining of the dielectric layer pressing state parameters of the high-density interconnected circuit board includes: obtaining the high-temperature pressing duration of the dielectric layer of the high-density interconnected circuit board.

By performing pressing adjustment processing on the dielectric layer pressing state parameter and the preset pressing state parameter, it is convenient to determine the difference between the current in-board dielectric layer pressing state of the high-density interconnected circuit board and the standard pressing state, so as to facilitate determining the degree of difference in pressing deformation of the current dielectric layer of the high-density interconnected circuit board. The dielectric layer pressing state parameter includes the high-temperature pressing duration of the dielectric layer of the high-density interconnected circuit board, and the high-temperature pressing duration of the dielectric layer is the high-temperature pressing time to which the in-board dielectric layer of the high-density interconnected circuit board is subjected during the pressing process, that is, the high-temperature pressing duration of the dielectric layer is the high-temperature pressing time when the internal dielectric layer of the high-density interconnected circuit board is pressed. By collecting the high-temperature pressing duration of the dielectric layer, it is convenient to determine the high-temperature pressing time that the dielectric layer of the high-density interconnection circuit board is subjected to in the current pressing process. By calculating the difference between the high-temperature pressing duration of the dielectric layer and the preset high-temperature pressing time, it is convenient to determine the degree of difference between the high-temperature pressing time that the dielectric layer of the high-density interconnection circuit board is subjected to in the current pressing process and the standard high-temperature pressing time.
[0050] Furthermore, the medium pressing warning start and stop signal is sent to the circuit board pressing host computer according to the medium pressing adjustment amount to adjust the board edge pressing mode of the high-density interconnected circuit board, including: detecting whether the medium pressing high temperature time adjustment matches the preset high temperature time adjustment; when the medium pressing high temperature time adjustment does not match the preset high temperature time adjustment, a medium pressing warning start signal is sent to the circuit board pressing host computer to stop the board edge pressing of the high-density interconnected circuit board. In this embodiment, the medium pressing adjustment amount is obtained based on the medium layer pressing state parameter and the preset pressing state parameter, and the medium layer pressing state parameter is the current in-board medium layer pressing condition of the high-density interconnected circuit board, that is, the medium layer pressing state parameter is the medium layer pressing process data under the current pressing process of the high-density interconnected circuit board, that is, the medium layer pressing state parameter corresponds to the medium layer pressing operation condition of the high-density interconnected circuit board. By collecting the dielectric layer pressing state parameters, it is convenient to determine the pressing execution condition of the dielectric layer in the board of the high-density interconnected circuit board during the pressing process. The preset pressing state parameters are the standard dielectric layer pressing conditions in the board of the high-density interconnected circuit board, that is, the preset pressing state parameters are the specified dielectric layer pressing process data under the pressing process of the high-density interconnected circuit board, that is, the preset pressing state parameters correspond to the reference operation conditions of the dielectric layer pressing of the high-density interconnected circuit board. By performing pressing adjustment processing on the dielectric layer pressing state parameters and the preset pressing state parameters, it is convenient to determine the difference between the current dielectric layer pressing state in the board of the high-density interconnected circuit board and the standard pressing state, so as to facilitate the determination of the degree of difference in pressing deformation of the current dielectric layer of the high-density interconnected circuit board. After obtaining the dielectric pressing adjustment amount, by sending the dielectric pressing warning start-stop signal to the circuit board pressing host computer, it is convenient to accurately control the pressing of the dielectric layer of the high-density interconnected circuit board, so as to avoid the situation where the dielectric layer of the board edge of the high-density interconnected circuit board overflows too much and causes the dielectric layer thickness to be too small. The dielectric layer pressing state parameter includes the dielectric layer pressing high temperature duration of the high-density interconnected circuit board. The dielectric layer pressing high temperature duration is the high temperature pressing time to which the dielectric layer in the board of the high-density interconnected circuit board is subjected during the pressing process, that is, the dielectric layer pressing high temperature duration is the high temperature pressing time when the internal dielectric layer of the high-density interconnected circuit board is pressed. By collecting the dielectric layer pressing high temperature duration, it is convenient to determine the high temperature pressing time to which the dielectric layer of the high-density interconnected circuit board is subjected in the current pressing process. By calculating the difference between the dielectric layer pressing high temperature duration and the preset high temperature pressing time, it is convenient to determine the degree of difference between the high temperature pressing time to which the dielectric layer of the high-density interconnected circuit board is subjected in the current pressing process and the standard high temperature pressing time.The medium high-temperature pressing time deviation does not match the preset high-temperature pressing time deviation, indicating that the high-temperature pressing time to which the medium layer of the high-density interconnected circuit board is subjected in the current pressing process is too short or too long, that is, it indicates that the amount of glue flowing at the edge of the board of the high-density interconnected circuit is too little or too much. At this time, the board edge pressing of the high-density interconnected circuit board is stopped to avoid excessive pressing of the high-density interconnected circuit board resulting in excessive glue flowing at the edge of the board, and also to avoid insufficient thickness of the medium layer in the high-density interconnected circuit board.
[0051] In another embodiment, when the medium high temperature pressing time difference matches the preset high temperature pressing time difference, a medium pressing warning closing signal is sent to the circuit board pressing host computer. The medium high temperature pressing time difference matches the preset high temperature pressing time difference, indicating that the high temperature pressing time to which the medium layer of the high-density interconnected circuit board is subjected in the current pressing process is just right, that is, the amount of glue flow at the edge of the high-density interconnected circuit is appropriate, so that the thickness of the edge of the board is maintained within the tolerance range, ensuring that the thickness of the medium layer of the high-density interconnected circuit is accurately controlled within the standard medium thickness.
[0052] During the actual pressing operation of the high-density interconnected circuit board, when the dielectric layer in the high-density interconnected circuit board is pressed by the mold of the pressing machine, the dielectric layer flows to the edge of the board after being squeezed, so that the dielectric layer is filled in the board in a planar distribution manner. After the dielectric layer reaches the specified dielectric thickness, it is still affected by the residual heat of the pressing, resulting in a too long curing time of the dielectric layer, which causes the dielectric layer to be in a state of strong fluidity after reaching the specified dielectric thickness, and then causes the dielectric layer to flow out from the edge of the board under the action of gravity of each layer of the core board, affecting the thickness consistency of the dielectric layer.
[0053] In order to improve the thickness consistency of the dielectric layer, the method further includes the following steps: sending a dielectric pressing warning start-stop signal to a circuit board pressing host computer according to the dielectric pressing level difference to adjust the board edge pressing mode of the high-density interconnection circuit board:
[0054] Obtaining the spacing of the exhaust grooves of the copper blocks at the edge of the high-density interconnection circuit board;
[0055] Detect whether the spacing between the exhaust grooves of the copper block at the edge of the board is greater than or equal to the preset exhaust groove spacing;
[0056] When the spacing between the exhaust grooves of the copper block at the edge of the board is greater than or equal to the preset exhaust groove spacing, an increase-pound-reduction signal is sent to the circuit board pressing host computer to increase the pressing force and reduce the pressure contact time at the same time.
[0057] In this embodiment, the spacing between the exhaust grooves of the copper block at the edge of the board is the spacing between the PADs at the edge of the high-density interconnection circuit board. Figure 2 and 3 The edge of the high-density interconnection circuit board is provided with a plurality of evenly distributed copper blocks to fill the edge area of the board. Here, the copper blocks replace the original circular PAD. The size of the copper blocks is 17*17mm, and the standard spacing between the copper blocks is 1.28mm, that is, the preset exhaust groove spacing. Board edge copper block exhaust grooves are formed between adjacent copper blocks. The gas in the dielectric layer during pressing is quickly discharged through the board edge copper block exhaust grooves to avoid the situation where the thickness of the dielectric layer is inconsistent due to the residual gas in the dielectric layer. The spacing between the exhaust grooves of the copper blocks at the edge of the board is greater than or equal to the preset exhaust groove spacing, indicating that the slot diameter of the exhaust grooves of the copper blocks at the edge of the board of the high-density interconnected circuit board is larger, that is, it indicates that the spacing between the copper blocks at the edge of the board of the high-density interconnected circuit board is wider. At this time, although the gas in the dielectric layer can be quickly discharged, it is also easy to cause the flowing dielectric layer to flow out quickly. In order to reduce the probability of outflow of the dielectric layer, an increase-pound and decrease-contact signal is sent to the circuit board pressing host computer to increase the pressing force and reduce the pressure contact time at the same time, so that the gas in the dielectric layer is increased by the extrusion pressure and the gas discharge is accelerated, but the pressing contact time at this time is shortened simultaneously, so that after as much gas as possible is discharged, the dielectric layer can be prevented from being squeezed out through the exhaust grooves of the copper blocks at the edge of the board.
[0058] Furthermore, the detecting whether the spacing between the exhaust slots of the copper block at the edge of the board is greater than or equal to the preset exhaust slot spacing further includes:
[0059] When the spacing between the exhaust grooves of the copper block at the edge of the board is less than the preset exhaust groove spacing, obtaining the pressing process section time of the high-density interconnection circuit board;
[0060] Detecting whether the pressing process section time is greater than a preset process section time;
[0061] When the pressing process section time is greater than the preset process section time, a weight reduction and contact raising signal is sent to the circuit board pressing host computer to reduce the pressing square inch pound force and at the same time extend the pressure contact time.
[0062] In this embodiment, the spacing between the exhaust grooves of the copper block at the edge of the board is smaller than the preset exhaust groove spacing, indicating that the slot diameter of the exhaust groove of the copper block at the edge of the board of the high-density interconnection circuit board is too small, that is, the spacing between the copper blocks at the edge of the board of the high-density interconnection circuit board is too fine. Although it can effectively delay the outflow probability of the dielectric layer, the gas discharge rate in the dielectric layer is also reduced synchronously, which easily leads to the dielectric layer being blocked in the exhaust groove of the copper block at the edge of the board and unable to be exhausted. At this time, by collecting the time of the pressing process section, it is convenient to determine the running time of the high-density interconnection circuit board in the current pressing process section, so as to facilitate the determination of the remaining time allowed for the pressing action of the high-density interconnection circuit board. The pressing process section time is greater than the preset process section time, indicating that the remaining time allowed for the pressing action of the high-density interconnected circuit board is too short, that is, the remaining pressing time of the high-density interconnected circuit board in the current pressing process section is too short, that is, the distance from the dielectric layer on the high-density interconnected circuit board to the exhaust groove of the copper block at the edge of the board is too short. By sending a weight reduction and connection raising signal to the circuit board pressing host computer to reduce the pressing force and extend the pressure contact time at the same time, the gas in the dielectric layer can be continuously discharged, and the flow rate of the dielectric layer is low, so as to avoid the dielectric layer flowing before the gas in the dielectric layer is completely discharged from blocking the exhaust groove of the copper block at the edge of the board.
[0063] In another embodiment, when the pressing process segment time is less than or equal to the preset process segment time, step S300 is performed.
[0064] In another embodiment, the pressing parameters corresponding to the pressing sections of the high-density interconnect circuit board are different, and the specific design is shown in Table 1 below.

[0068] The above-mentioned various preset variables are all set in the database for timely retrieval, and different preset variables are placed in different storage units, that is, in different storage stacks. Moreover, the spacing between the exhaust grooves of the copper blocks on the edge of the board and the time of the pressing process can be collected by corresponding detectors, for example, by the CCD camera in the pressing collection module and the pressing timer.

[0070] In this embodiment, after the pressing acquisition module collects the pressing state parameters of the dielectric layer, the pressing state of the current dielectric layer in the high-density interconnected circuit board is determined, and then the board edge pressing processing module compares the dielectric layer pressing state parameters with the standard dielectric layer pressing parameters to facilitate determining the difference between the current pressing state of the dielectric layer in the high-density interconnected circuit board and the standard pressing state of the dielectric layer in the board. Finally, the pressing warning module optimizes and adjusts the pressing working mode of the circuit board pressing host computer according to the above difference value, thereby effectively reducing the probability of scrapping the circuit board.
