Description

Technical Field

[0001] This utility model relates to the field of SIP module testing technology, specifically to an automatic control system for testing waveguide-type SIP modules. Background Technology

[0002] SIP module testing is a crucial step in the semiconductor manufacturing industry. Every SIP module produced must undergo relevant tests to meet specific performance requirements before proceeding to the next stage of manufacturing. With the increasingly widespread application of SIP system integration packaging, a large number of SIP modules require testing. Currently, the industry largely uses traditional SIP module testing methods, which involve manually connecting the SIP module's pins to a control board using gold wire bonding, and then manually switching the RF and DC links of the SIP module. Testers manually switch the DC power supply, change test channels, and record test data. This traditional testing method is cumbersome, inefficient, requires a large number of personnel, and is prone to errors due to manual testing. It can no longer meet the needs of the rapidly evolving semiconductor manufacturing industry. Therefore, there is an urgent need for an accurate, convenient, efficient, and intelligent testing system. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic control system for testing waveguide-type SIP modules.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] This utility model provides an automatic control system for testing waveguide-type SIP modules, including a motion controller, a host computer, a switch, a camera, a bus stepper servo motor, a handwheel, an emergency stop button, status indicator lights, and a vacuum suction cup. The motion controller is connected to the switch, the bus stepper servo motor, the handwheel, the emergency stop button, the status indicator lights, and the vacuum suction cup. The switch is connected to the monitoring host computer, which is connected to the camera. The camera is used to observe the position of the probe during testing. The handwheel is used to control the bus stepper servo motor during installation and debugging. The status indicator lights are used to display the system's operating or fault status. The vacuum suction cup is used to quickly pick up the SIP module.

[0006] Furthermore, it also includes a power supply module. After the external power supply is connected to the control system, it is connected to the input terminal of the power supply module. The output terminal of the power supply module is connected to the input terminals of the two power supply modules. The power supply module is equipped with a key switch. By switching the state of the key switch, power is supplied to the two power supply modules. One power supply module outputs 48V for the bus stepper servo motor, and the other power supply module outputs 24V for the motion controller.

[0007] Furthermore, the motion controller is equipped with an AXIS port for connecting the handwheel encoder interfaces B, A, B-, A- and the power supply terminals VCC and 0V; the motion controller is also equipped with a DI module and a DO module, the DI module is used to connect the XYZ axis selection terminal and the magnification terminal of the handwheel; the DO module is used to connect the status indicator light and the fault indicator light; the DO module is also connected to an intermediate relay, which drives the vacuum solenoid valve through its contacts, and is connected to a fuse to prevent excessive current.

[0008] Preferably, the power supply ports VDC and GND of the bus stepper servo motor are connected to a 48V power supply provided by the output power supply, and the input ports of the bus stepper servo motor are connected to three external signals, namely the origin switch, the forward limit switch and the reverse fiber switch, for the zero return and limit protection of the motion axis.

[0009] The beneficial effects of this utility model are:

[0010] 1) This utility model provides an automatic control system for testing waveguide-type SIP modules. Compared with the manual testing of SIP modules that is still widely used, the core technology is to use a motion controller to program an automatic test for fully automatic testing. No human intervention is required during the test, which greatly shortens the testing time of SIP modules and reduces manual measurement errors.

[0011] 2) This invention simultaneously uses EtherCAT communication to control multiple motors, greatly reducing the number of motor control circuits and solving the problem of requiring a large number of control circuits in traditional motor control. It also employs fully automated testing; the tester only needs to place the SIP on the test bench and click the automatic test button on the host computer to complete the test automatically, saving the test data and generating reports. No human intervention is required throughout the process, reducing measurement errors, greatly improving testing speed, and lowering labor costs. Attached Figure Description

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] This invention provides an automatic control system for testing waveguide-type SIP modules. It is not only simple in structure, highly automated, and easy to operate and maintain with a short time response cycle, but also reduces human measurement errors. This improves testing efficiency and ensures the accuracy of test data, thereby ensuring a higher yield of SIP modules flowing into the next production stage and meeting the needs of the current semiconductor manufacturing industry.

[0018] The structural schematic diagram of this utility model is shown below. Figure 1 As shown, the system includes a motion controller, a host computer, a switch, a camera, a bus stepper servo motor, a handwheel, an emergency stop button, status indicator lights, and a vacuum suction cup. The camera is used to observe whether the probe's position deviates during testing. The handwheel facilitates control of the bus stepper servo motor during installation and debugging. The status indicator lights display the system's operating or fault status. The vacuum suction cup quickly picks up the SIP module, eliminating the need for screws and reducing the time required to replace SIP modules, thus improving work efficiency.

[0019] For example, the power supply circuit diagram of this utility model is shown below. Figure 2 As shown, it also includes a power supply module. An external AC220V power supply is connected to the control system and then connected to the power supply module's input terminal. The power supply module's output terminal is connected to the input terminals of the two power supply modules. Each power supply module is equipped with a key switch. Switching the key switch's state supplies power to the two power supply modules. One power supply module outputs 48V to power the bus stepper servo motor, while the other outputs 24V to power the motion controller and other related equipment. Simultaneously, a power indicator light shows that the system is powered on.

[0020] For example, the schematic diagram of the input / output circuit of the motion controller of this utility model is as follows: Figure 3As shown; the motion controller's power supply terminal is connected to a 24V power supply, and the AXIS port is connected to the handwheel encoder interfaces B, A, B-, A-, as well as the power supply terminals VCC and 0V. Simultaneously, the handwheel's XYZ axis selection terminals and magnification terminals are connected to the motion controller's DI module. The status indicator and fault indicator are connected to the motion controller's DO module. Considering the relatively large load required by the vacuum solenoid valve, the motion controller's DO port cannot directly drive the vacuum solenoid valve. Therefore, the motion controller's DO module is connected to an intermediate relay, which drives the vacuum solenoid valve through its contacts. A fuse is connected to prevent excessive current from damaging the vacuum solenoid valve.

[0021] For example, the power supply and signal circuit diagram of the stepper servo motor of this utility model is shown in the figure below. Figure 4 As shown; each motor is exactly the same, so the following description uses one unit. The bus stepper servo motor's power supply ports VDC and GND are connected to the 48V power supply provided by the 48V power module. The bus stepper servo motor's own input ports are connected to three external signals: a home switch, a forward limit switch, and a reverse fiber switch. These are used for zero-return and limit protection of the motion axis.

[0022] The core of the entire automatic control system is the motion controller. It connects to a host computer via Ethernet through a switch. The motion controller receives motion commands from the host computer, makes corresponding judgments, and then controls multiple motion axis motors in different directions via industrial Ethernet (EtherCAT) bus communication. The system first opens the vacuum solenoid valve to firmly attach the SIP module to the fixture. Then, the probes (X and Z axes), the waveguide transmitters (X, Y, and Z axes), and the waveguide receivers (X, Y, and Z axes) move to their corresponding positions for testing according to preset data. After testing one channel, it automatically moves to the next channel for testing. After testing multiple channels, the system terminates and automatically generates a test data report. The tester simply removes the axis SIP module, places it in the next module, and begins testing again.

[0023] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
