Description

Technical Field

[0001] This invention relates to the field of semiconductor packaging technology, and specifically to a carrier tape tensile testing system and method. Background Technology

[0002] In the semiconductor packaging industry, before chips are delivered to customers after packaging, multiple chips need to be sealed together using carrier tape and cover tape to form a closed package. The carrier tape and cover tape are then wound together to form a roll for easy transport. During the sealing process, the peel strength of the carrier tape needs to be tested to check whether it meets performance requirements.

[0003] Existing testing methods utilize carrier tape tensile testing equipment. During testing, the carrier tape is placed on the equipment, and the type of carrier tape and test parameters are manually entered. The equipment is then started, and the results are displayed. If the test results meet the requirements, the carrier tape can proceed with sealing; otherwise, it needs to be replaced. However, this method has a vulnerability during production: incorrect carrier tape selection may go undetected. For example, if a larger carrier tape is used for chip sealing, and the chip is shipped after the tensile test, the larger size of the carrier tape creates a gap within the sealed space. During transport, chip movement can cause the sealed carrier tape to crack, leading to chip contamination and damage, resulting in customer returns and complaints. Therefore, a new solution is urgently needed. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a carrier tape tensile testing system and method to solve the problem that the incorrect selection of carrier tape type in the existing carrier tape tensile testing cannot be detected, which leads to chip contamination and damage, resulting in customer returns and complaints.

[0005] The technical solution to achieve the above objectives is:

[0006] This invention provides a carrier tape tensile strength testing method for testing carrier tapes of sealed packaged chips. The method comprises the following steps:

[0007] Establish a connection with a carrier tape tensile tester to obtain the dimensional parameters of the chip sealed by the carrier tape to be tested placed on the carrier tape tensile tester;

[0008] The matching carrier type is found based on the obtained chip size parameters;

[0009] Receive the input batch number data, and find the corresponding test parameters based on the received batch number data. The test parameters include the type of carrier tape to be tested.

[0010] The system compares the type of carrier tape matching the chip with the type of the carrier tape to be tested. If the comparison result is inconsistent, an alarm is triggered; if the comparison result is consistent, the found test parameters are sent to the carrier tape tensile tester to complete the carrier tape test.

[0011] After the carrier tape test is completed, obtain the test results of the carrier tape and store them for future reference.

[0012] The carrier tape tensile testing method of this invention compares the size parameters of the chip sealed by the carrier tape actually placed on the carrier tape tensile tester with the input carrier tape type. If they are inconsistent, an alarm is triggered. This allows for checking the selected carrier tape type for chip sealing before testing, preventing human error and promptly identifying and avoiding quality problems such as packaging breakage. Furthermore, it provides an automatic parameter addition function; users only need to manually input the batch number data, making operation convenient and preventing parameter input errors.

[0013] A further improvement to the carrier belt tensile testing method of the present invention is that it further includes:

[0014] Pre-store a table showing the correspondence between batch numbers and test parameters;

[0015] After receiving the batch number data, the corresponding test parameters are looked up from the pre-stored batch number and test parameter correspondence table.

[0016] A further improvement to the carrier belt tensile testing method of the present invention is that it further includes:

[0017] Pre-stored chip and carrier tape matching table;

[0018] After obtaining the chip's size parameters, the type of carrier tape that matches the chip is found from the pre-stored chip-carrier tape matching table.

[0019] A further improvement of the carrier belt tensile testing method of the present invention is that, after obtaining the test results of the carrier belt, the test results of the carrier belt, along with the corresponding test parameters and batch number data, are stored in the form of a document.

[0020] A further improvement of the carrier belt tensile testing method of the present invention is that the test parameters include test temperature parameters and test pressure parameters.

[0021] The present invention also provides a carrier belt tensile testing system, connected to the carrier belt tensile tester, the testing system comprising:

[0022] The acquisition module is used to acquire the size parameters of the chip sealed by the carrier tape to be tested placed on the carrier tape tensile tester;

[0023] The input module is used to receive the input batch number data;

[0024] The lookup module, connected to the acquisition module and the input module, is used to find the matching carrier type based on the chip size parameters acquired by the acquisition module, and is also used to find the corresponding test parameters based on the batch number data received by the input module, the test parameters including the carrier type;

[0025] The processing module, connected to the acquisition module and the search module, is used to compare and determine whether the type of the carrier tape matching the chip is consistent with the type of the carrier tape to be tested found. If the comparison result is inconsistent, an alarm command is generated to provide an alarm reminder; if the comparison result is consistent, a sending command is generated to send the found test parameters to the carrier tape tensile tester for execution; after the carrier tape tensile test is completed, the acquisition module acquires and stores the test results of the carrier tape for easy viewing.

[0026] A further improvement of the carrier belt tensile testing system of the present invention is that it also includes a storage module, wherein the storage module pre-stores a table of correspondence between batch number and test parameters;

[0036] Figure 5 This is a schematic diagram of the structure of the test report generated by the carrier belt tensile testing system of the present invention.

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] See Figure 1 This invention provides a carrier tape tensile testing system and method, which connects to a carrier tape tensile tester to control the tester in performing carrier tape tests, including tests on the mechanical properties of the carrier tape such as tension, compression, peel, tear, and shear. Before testing, the system compares the carrier tape type matched to the chip with the input type to determine if they match. If they do not match, an alarm is triggered, allowing for timely detection of manual carrier tape selection errors and preventing chip contamination and damage due to incorrect carrier tape selection. Furthermore, the testing system and method can retrieve the corresponding test parameters based on the batch number data entered by the operator, eliminating the need for manual input and improving testing efficiency while reducing input errors. Additionally, the system and method can acquire and store the test results from the carrier tape tensile tester for convenient result management. The carrier tape tensile testing system and method of this invention will be described below with reference to the accompanying drawings.

[0039] See Figure 1 The diagram below shows the system diagram of the carrier belt tensile testing system of the present invention. Figure 1 The present invention will describe the carrier belt tensile testing system.

[0040] like Figure 1As shown, the carrier tape tensile testing system of the present invention is connected to the carrier tape tensile testing instrument. The testing system includes an acquisition module 21, an input module 22, a search module 23, and a processing module 24. The search module 23 is connected to the input module 22, and the processing module 24 is connected to the acquisition module 21 and the search module 23. The acquisition module 21 is used to acquire the dimensional parameters of the chip sealed by the carrier tape to be tested, placed on the carrier tape tensile testing instrument. The input module 22 is used to receive input batch number data. The search module 23 is used to find a matching carrier tape based on the dimensional parameters of the chip acquired by the acquisition module 21. The type of data is also used to find the corresponding test parameters based on the batch number data received by the input module 22. The test parameters include the carrier tape type. The processing module 24 is used to compare and determine whether the type of the carrier tape that matches the chip is consistent with the type of the carrier tape to be tested. If the comparison and determination result is inconsistent, an alarm command is generated to provide an alarm reminder. If the comparison and determination result is consistent, a sending command is generated to send the found test parameters to the carrier tape tensile tester for execution. After the carrier tape tensile test is completed, the test results of the carrier tape are obtained by the acquisition module 21 and stored for easy viewing.

[0041] The carrier tape tensile testing system of the present invention is used to find out the carrier tape type that matches the sealed chip by obtaining the size of the sealed chip placed on the carrier tape tensile tester before testing the carrier tape, and then compare it with the input carrier tape type to promptly detect whether the selection of the carrier tape type is accurate, thus playing a role in preventing mistakes.

[0042] In one specific embodiment of the present invention, the testing system of the present invention further includes a storage module, which pre-stores a table of correspondence between batch numbers and test parameters;

[0043] The lookup module 23 is connected to the storage module and is used to look up the test parameters corresponding to the batch number data from the batch number and test parameter correspondence table.

[0044] By pre-setting a correspondence table between batch numbers and test parameters, the system can obtain the corresponding test parameters simply by inputting the batch number data, eliminating the need for manual input and improving the efficiency of testing operations.

[0045] Furthermore, the test parameters include test temperature parameters and test pressure parameters.

[0046] like Figure 3 and Figure 4 As shown, the test parameters also include machine code, package type, customer, stripping method, specification number, and sealing time. Through... Figure 3 When the batch number is entered in the displayed interface, the system can directly retrieve the above test parameters and fill them into the corresponding data boxes for display.

[0047] In one specific embodiment of the present invention, the storage module also pre-stores a chip-carrier matching table;

[0048] The lookup module 23 is used to find the type of carrier tape that matches the chip from the chip and carrier tape matching table.

[0049] Furthermore, the chip-carrier matching table stores the chip name, size information, and matching carrier part number.

[0050] Preferably, the chip's dimensions include its length, width, and height.

[0051] After the carrier tape to be tested is placed on the carrier tape tensile tester, the length, width and height of the chip sealed on the carrier tape are measured to obtain the chip size parameters. Then, based on the chip size parameters, the corresponding carrier tape is found from the chip and carrier tape matching relationship table.

[0052] In one specific embodiment of the present invention, the processing module 24 is connected to the storage module and is used to store the test results of the carrier tape and the corresponding test parameters and batch number data in the form of a document.

[0053] Furthermore, the processing module 24 is also used to perform data analysis and processing on the test results of the carrier tape to generate data charts and store them for easy viewing.

[0054] like Figure 5 As shown, the processing module 24 summarizes the test results, test parameters, and generated data charts into a test report for display. After receiving the save instruction, the test report is stored in the storage module as a document.

[0055] In one specific embodiment of the present invention, the carrier belt tensile testing system is installed on a PC as an application program. The PC is connected to the carrier belt tensile tester via a communication cable, thereby enabling data communication between the two instruments. The testing system also includes a display interface. After the testing system is started, the processing module displays this interface for user operation. Figure 3 The diagram shows the display interface. Users can manually enter the batch number. The testing system retrieves the batch number, finds the corresponding test parameters, and then fills the test parameters into the corresponding data boxes, as shown below. Figure 4As shown, the user then clicks the "Okay" button to confirm the input. The testing system compares the input carrier tape type with the carrier tape type corresponding to the chip on the carrier tape tensile tester. If the comparison results are inconsistent, an alarm is triggered, an error message indicating an incorrect carrier tape type is selected is displayed on the screen, and the "Setup" button is grayed out and unclickable. If the comparison results are consistent, the "Setup" button is made clickable, and the user clicks it to initiate the test. The testing system then sends the test parameters to the carrier tape tensile tester to control it to perform the test. Upon receiving the test parameters, the carrier tape tensile tester controls the motor to move under the specified test parameters. The sensor detects the force change and records and displays the test data results. The testing system then acquires the test results obtained by the carrier tape tensile tester and stores and displays them in a designed document format.

[0056] The present invention also provides a method for testing the tensile strength of a carrier belt, which is described below.

[0057] The carrier tape tensile strength test method of the present invention is used to test the carrier tape of sealed packaged chips, such as... Figure 2 As shown, the test method includes the following steps:

[0058] Execute step S11 to establish a connection with a carrier tape tensile tester and obtain the dimensional parameters of the chip sealed by the carrier tape to be tested placed on the carrier tape tensile tester; then execute step S12.

[0059] Execute step S12 to find the matching carrier type based on the obtained chip size parameters; then execute step S13.

[0060] Execute step S13, receive the input batch number data, find the corresponding test parameters based on the received batch number data, the test parameters include the type of carrier tape to be tested; then execute step S14.

[0061] Execute step S14 to compare and determine whether the type of the carrier tape that matches the chip is consistent with the type of the carrier tape to be tested. If the comparison result is inconsistent, then execute step S17.

[0062] If the comparison result is consistent, then proceed to step S15;

[0063] Execute step S15 to send the found test parameters to the carrier belt tensile tester to complete the carrier belt test; then execute step S16.

[0064] Execute step S16: After the carrier tape test is completed, obtain the test results of the carrier tape and store them for easy viewing.

[0065] Execute step S17 to trigger an alarm.

[0066] The carrier tape tensile testing method of this invention compares the size parameters of the chip sealed by the carrier tape actually placed on the carrier tape tensile tester with the input carrier tape type. If they are inconsistent, an alarm is triggered. This allows for checking the selected carrier tape type for chip sealing before testing, preventing human error and promptly identifying and avoiding quality problems such as packaging breakage. Furthermore, it provides an automatic parameter addition function; users only need to manually input the batch number data, making operation convenient and preventing parameter input errors.

[0067] In one specific embodiment of the present invention, the testing method further includes:

[0068] Pre-store a table showing the correspondence between batch numbers and test parameters;

[0069] After receiving the batch number data, the corresponding test parameters are looked up from the pre-stored batch number and test parameter correspondence table.

[0070] In one specific embodiment of the present invention, the testing method further includes: pre-storing a chip-carrier matching relationship table; and after obtaining the chip size parameters, searching for the matching carrier type from the pre-stored chip-carrier matching relationship table.

[0071] In one specific embodiment of the present invention, after obtaining the test results of the carrier tape, the test results of the carrier tape, along with the corresponding test parameters and batch number data, are stored in the form of a document.

[0072] In one specific embodiment of the present invention, the test parameters include test temperature parameters and test pressure parameters.

[0073] In one specific embodiment of the present invention, the testing method further includes:

[0074] Provide an operation interface and display a batch number input box on the operation interface to facilitate the input of batch number data.

[0075] The testing system and method of this invention are computer-operated and can output test graphs and tabular data as test reports. The testing system and method of this invention can analyze the entire test result and the characteristics of the test sample, such as tensile force, strain, and average value, resulting in more accurate test results. The use of signal transmission ensures error-free information conversion. The carrier tensile tester has stress, strain, and displacement modes and can calculate parameters such as maximum force, tensile strength, flexural strength, compressive strength, elastic modulus, elongation at break, and yield strength. It is suitable for mechanical property tests and analyses involving tension, compression, peeling, tearing, and shearing.
