Description

Technical Field

[0001] This invention relates to the field of semiconductor manufacturing, and in particular to a method and medium for setting parameters of a tape and reel machine based on automatic system writing and comparison. Background Technology

[0002] Chip taping is a critical process in the back-end of semiconductor manufacturing. It automatically and precisely packages individual chips that have been tested and confirmed to be good into a special carrier tape, seals it with a plastic film, and finally winds it into a reel for subsequent surface mount technology (SMT) for high-speed PCB board mounting.

[0003] A typical back-end chip testing process is as follows:

[0004] Wafer testing → Wafer sawing → Chip bonding → Soldering / encapsulation → Final testing → Tape and reel operation → Marking / printing → Packaging / warehousing.

[0005] In a typical chip testing back-end process, tape and reel operation is located after final testing and before marking / printing, and is one of the last few critical steps before the chip leaves the factory.

[0006] The input parameters of the tape and reel machine are the brain and instruction set of the tape and reel operation. Before starting production of a new model of chip, the operator or engineer must set a series of precise parameters in the control system of the tape and reel machine. These parameters are usually input through a human-machine interface (HMI, i.e., touch screen) and stored as a separate recipe. These parameters are the recipe that the operator inputs into the tape and reel machine before production begins, based on the chip model and specifications to be tapered, etc., and their purpose is to tell the tape and reel machine how to correctly process and package the current batch of chips. In the prior art, tape and reel machine parameters are manually entered by personnel, and the files are stored locally, making them susceptible to improper modification. Obviously, this easily leads to parameter errors, resulting in problems such as defective products being shipped out.

[0007] Therefore, it is necessary to develop a new method for setting up a tape and reel machine.

[0008] The information disclosed in the background section is only intended to enhance the understanding of the background of the present invention, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0021] S14: If an updated version is detected, step S12 is automatically re-executed to match the latest tape-and-reel operation standard data based on the updated version.

[0026] S54: If the comparison results are inconsistent, an error message will be generated and the current work order process will be interrupted.

[0027] Preferably, in step S51, the effective tape and reel machine operating parameters are read, including:

[0028] The effective operating parameters of the tape and reel machine can be read by reading the unencrypted temporary parameter file stored locally on the device, which is generated or referenced by the tape and reel machine control software during runtime.

[0029] Preferably, in step S2, the preset network storage path is set in advance in the configuration software of the tape and reel machine.

[0030] Preferably, in step S3, the tape and reel machine control software is configured to always load a unique configuration file from the network storage path, and to ensure that the device locally retains only the currently effective parameter file.

[0065] See Figure 2In another embodiment, the present invention also discloses a method for setting tape and reel machine parameters based on automatic system writing and comparison, comprising the following steps: Work order personnel link the work order to the ERP system; the ERP system automatically matches the product appearance parameters in the tape and reel operation standards according to the work order information, wherein the tape and reel operation standards are pre-established and approved by the system when a new product is introduced, and only key personnel are allowed to modify the tape and reel operation standards; the matched product appearance parameters are written to a configuration file in a preset cloud drive path, the cloud drive path being pre-set in the tape and reel machine's configuration software; the configuration software loads the configuration file from the cloud drive path, automatically updating the tape and reel machine parameters; the set tape and reel machine parameters are read, and the read tape and reel machine parameters are automatically compared and verified with the product appearance parameters; when the comparison and verification pass, trial production or formal production begins; when the comparison and verification fail, an error is reported in the work order.

In another embodiment, the configuration software retains only one configuration file locally. In yet another embodiment, the set tape and reel machine parameters are read by reading the unencrypted temporary parameter file of the configuration software. For example, the unencrypted temporary parameter file is an unencrypted temporary parameter file generated or referenced by the tape and reel machine control software during runtime and stored locally on the device. In yet another embodiment, before the work order personnel connect to the ERP system based on the work order, the process further includes: equipment personnel retrieving parts and setting up the machine hardware based on the work order information in the ERP system.In another embodiment, the present invention also provides an automatic parameter writing system for a chip taping and reeling machine, comprising: an ERP system for automatically matching product appearance parameters in the taping and reeling operation standard according to work order information, wherein the taping and reeling operation standard is pre-established and approved by the system when a new product is introduced, and only key personnel are allowed to modify the taping and reeling operation standard; a cloud drive storage module for storing configuration files containing matching product appearance parameters; taping and reeling machine configuration software pre-set with a cloud drive path for loading configuration files from the cloud drive path and automatically updating taping and reeling machine parameters; a parameter verification module for reading the set taping and reeling machine parameters and automatically comparing and verifying the read taping and reeling machine parameters with the product appearance parameters; and an alarm module for posting an error message when the comparison and verification fails. In another embodiment, the local end of the taping and reeling machine configuration software retains only one configuration file. In another embodiment, the parameter verification module reads the set taping and reeling machine parameters by reading the unencrypted temporary parameter file of the taping and reeling machine configuration software. In another embodiment, the ERP system also includes a version detection unit, which is used to determine whether there is an updated version of the tape-and-reel operation standard before the parameters are written into the configuration file. If an updated version exists, the product appearance parameters in the updated version of the tape-and-reel operation standard are re-matched.

[0066] In another embodiment, the present invention also discloses a computer storage medium comprising computer instructions that, when executed on a computer, cause the computer to perform any of the methods described above.

[0067] In another embodiment, see further. Figures 3 to 8 It illustrates the operation process of mass production based on the method disclosed in this invention:

[0068] according to Figure 3 As shown, perform the work order operation;

[0069] according to Figure 4 As shown, the system queries the corresponding database for the work standard based on the work order information.

[0070] according to Figure 5 As shown, the parameters of the work standard corresponding to the work order are written into the file named after the corresponding machine number, and the information corresponding to the parameters of the work standard can be updated as needed;

[0071] according to Figure 6 , Figure 7 As shown, when executing a specific tape-and-reel task, such as a Job, the parameter file is loaded and the local configuration file for that task is updated accordingly. The local configuration file includes, for example, the JobConfig description file, as well as general configuration information related to tape-and-reel, such as tape-and-reel pins and tape-and-reel characters.

[0072] according to Figure 8 As shown, the parameters of the setup software interface for mass production are updated accordingly. After the update, a sample is taken to set the character and pin parameters. Once the settings are complete, mass production can begin. Figure 8 As shown, PIN pin detection is performed based on pin parameters, and character detection is performed based on character parameters. When both are detected as NG, the following error message is displayed: "Failed to follow positioning template," thus demonstrating the automatic verification function.

[0073] In summary, this invention addresses the problems in the existing chip taping process, such as the ease with which manual input of taping machine parameters is prone to errors and the vulnerability of locally stored taping machine parameter files to improper modification, which lead to defective products being shipped out and affect production efficiency and product quality. Therefore, this invention provides a method, medium, and system for setting chip taping machine parameters that can automatically write parameters, prevent improper parameter modification, and have automatic verification functions.

[0074] The present invention also has the following characteristics:

[0075] The ERP system automatically matches parameters from the tape-and-reel operation standard based on work order information and automatically writes them into the tape-and-reel machine, avoiding errors that may occur from manual parameter input and significantly improving the accuracy of parameter settings. Through the system's review mechanism for the tape-and-reel operation standard and key personnel access control, combined with configuration file management via a central cloud storage system, the risk of unauthorized modification of locally stored parameter files is effectively prevented, achieving access control and version consistency for parameter modifications. The fully automated process of automatic matching, writing, and verification significantly shortens parameter setting time and improves the automation level and production efficiency of the production line. Through an automatic parameter comparison and verification mechanism and work order error reporting function, erroneous parameters can be detected and prevented from entering the production process during the parameter setting stage, effectively preventing defective products from leaving the production line and improving product yield and overall quality control. A version detection mechanism ensures that the latest version of the tape-and-reel operation standard is always used, and the configuration software retains only a single configuration file locally, avoiding multi-version confusion and guaranteeing the uniqueness and consistency of parameters.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
