[0053] In a core concept of an embodiment of the present invention, in an existing SLP type substrate processing method, after copper plating in the through hole, a dry film is made, and then a circuit pattern is etched out with a solution. When the copper plating layer is thicker, the size of the fine circuit and the small pad is smaller during etching, and the probability of residual copper between the circuits is relatively high; however, in an embodiment of the present invention, after copper plating in the through hole, the copper in the through hole protection hole is first covered with a dry film of a corresponding size, and the other exposed parts are pre-thinned with a solution of corrosion to reduce the copper thickness, and then the fine circuit and the small pad size are etched to ensure the etching quality, thereby ensuring the hole conduction reliability of the SLP type substrate, and at the same time, the fine circuit and the small pad size can be etched; specifically, it is necessary to take into account the dimensional error caused by the vibration characteristics of the robot arm of the automation equipment, and the offset is calculated by the vibration accuracy of the robot arm and the vibration coefficient of the equipment body, and the alignment coordinate parameters of the dry film are adjusted according to the offset, so as to improve the accuracy of the dry film pasting of the equipment, improve the processing efficiency and the accuracy of dimensional control.
[0054] Reference Figure 1 , shows a flow chart of steps of an SLP type carrier processing process control method embodiment of the present invention, which may specifically include the following steps:
[0055] Step 101, obtaining a carrier-like design drawing, and determining the position of the through hole in the carrier-like design drawing;
[0056] In an embodiment of the present invention, the processing technology control method can be applied to an integrated semiconductor device, which can be composed of multiple different types of semiconductor devices to realize the functions of multiple semiconductor processing steps, such as material pre-baking equipment, inner layer imaging equipment, drilling equipment, electroplating equipment, browning equipment, lamination and pressing equipment, dry film pasting equipment, exposure equipment, developing equipment, etching equipment, etc. The embodiment of the present invention does not impose too many restrictions on this. The above-mentioned multiple different types of semiconductor devices can be used by equipment such as a robotic arm to operate materials. Specifically, the robotic arm can also be configured with a variety of different devices such as an adsorption device. The embodiment of the present invention does not impose too many restrictions on this; the integrated semiconductor device is also connected to a control terminal or a server, which can be used to control the operation process of the above-mentioned equipment. The terminal can be but not limited to various personal computers, laptops, smart phones, tablet computers and portable wearable devices.

The terminal is connected to a variety of semiconductor devices, and the operating system of the terminal can include Android, Harmony OS, IOS, WindowsPhone, Windows, etc. The present invention does not impose too many restrictions on this.
[0057] Specifically, in the embodiment of the present invention, a quasi-substrate design drawing can be first obtained to determine the through-hole positions of the quasi-substrate design drawing; specifically, Figure 2 As shown, the through hole position can be directly identified by combining image recognition with annotation instructions.
[0058] In another preferred embodiment of the present invention, in the case of unclear markings and unclear design drawings, the obtaining of a quasi-carrier board design drawing and determining the position of the through hole in the quasi-carrier board design drawing include: identifying multiple front circular arc curves from the front design drawing of the quasi-carrier board; determining a first center position and a first circular area corresponding to the front circular arc curve; obtaining a second center position of the front design drawing of the quasi-carrier board that is in a mirror image position with the first center position; determining whether the second center position includes multiple reverse circular arc curves, and determining whether the second circular area corresponding to the multiple reverse circular arc curves is the same as the first circular area; if the second center position includes multiple reverse circular arc curves and the second circular area corresponding to the multiple reverse circular arc curves is the same as the first circular area, determining the first center position as the through hole position in the quasi-carrier board design drawing.
[0059] That is, when the marking is unclear and the design drawing is not clear, the arc curve of the front design drawing is identified by image recognition, and the center position and the corresponding circle area are determined according to the above arc curve; then according to the mirror position of the back design drawing of the same PCB, it is determined whether the circle area corresponding to the arc curve at the mirror position is the same as the first circle area. If so, it means that the hole at this position is a through hole, and the other holes are blind holes. In the embodiment of the present invention, only image recognition can be used to identify whether the hole is a through hole or a blind hole, without the need for marking, thereby improving recognition efficiency.
[0060] Step 102, controlling the device to apply a through-hole dry film to the corresponding position of the copper-plated substrate;

[0068] Furthermore, after the copper-plated substrate is affixed with a through-hole dry film, a first etching operation to reduce the copper thickness can be performed to obtain a copper-plated substrate with reduced copper thickness. Specifically, chemical etching can be used to reduce the copper thickness in other areas where the dry film is not affixed.
[0069] Step 104, the control device performs a dry film pattern transfer operation on the copper-plated substrate after the copper thickness is reduced, and then performs a second etching operation to obtain an SLP type carrier board including fine circuits and small pad sizes.
[0070] In actual application to the embodiment of the present invention, after the copper thickness reduction operation is performed, the device can be controlled to perform a dry film pattern transfer operation on the copper-plated substrate after the copper thickness reduction, and then a second etching operation can be performed. After the copper thickness is reduced, the etching of fine circuits and small pad sizes can ensure the etching accuracy, thereby ensuring the hole conduction reliability of the SLP type carrier board. At the same time, fine circuits and small pad sizes can be etched to ensure the dimensional accuracy of the circuit devices. The specific effects are as follows: Figure 3 shown.
