It can't meet the current information transmission volume of millions of bytes (Megabyte, #MB), so 'Optic fiber communication' The optical fiber communication system has the advantages of high information transmission capacity, etc., and is mainly composed of an optical coupling transmitting component, a fiber transmission channel, and a light-lighting receiving component. When implemented, the optical shank and the transmitting component are received. The digital signal is converted into a specific wavelength of optical signal, and transmitted by the optical fiber transmission channel, and finally received and demodulated into a digital signal by the optical coupling receiving component to complete the information transmission; Figure, the figure shows the electrical composition diagram of the current optical coupling receiver 201234026. As mentioned above, the optical coupling receiver is one of the main components in optical fiber communication, however, for optical coupling When the receiving component ίο is activated, a specific electrical phenomenon can be generated, which is an analog terminal operating voltage source avdd and a digital terminal operating voltage source of the optical coupling receiving component 10. Dm generates electrical connection, and in order to make the analog terminal working voltage source Avdd act, it is not interfered by the noise on the digital working voltage source Dvd1), and is connected between the two working voltage sources (Avdd and Dvdd). A low-resistance resistor rvdd to solve the problem of noise interference, please refer to "Figure 2". The figure shows the package diagram of the current optical coupling receiving component. As described above, the optical coupling receiving component 1 After the chip package is completed, the two working voltage sources (Avdd and Dvdd) are electrically connected, and are electrically connected to the voltage source pin vcc of the packaged optical coupling receiving element 1 ,, and the two grounding points (△ (4) And Dgnd) also produces an electrical connection 'and is electrically connected to the grounding pin Gnd of the receiving component 1〇, and the output terminal V〇UT is electrically connected to the output pin 〇ut, and optically coupled After the component 1 is mounted on the chip packaging process, although the package is completed, but in the automated process, it is inevitable that the two working voltage sources (Avdd and Dvdd) are not electrically connected (a shown in the figure). Please refer to "Figure 1" for two working voltage sources ( (4) Dvdd) does not produce an electrical connection 'the analog voltage of the analog terminal' is transmitted from the digital terminal operating voltage source dvdd to the analog terminal via the resistor RVDD, or the analog terminal is conducted to the digital terminal, and the resistance of the resistor Rvdd is higher. Small, the analog voltage obtained by the analog terminal is only slightly smaller than the digital terminal'. Therefore, the light-consuming receiving component can still be activated. Moreover, the optical coupling receiving component 10 can be activated, but when the optical signal is received, the 201234026 waveform missing is easily generated. In the case of waveform anomalies, the waveform omissions are as shown in "Figure 3". The figure shows the missing waveform of the received waveform, and the waveform anomaly is shown in Figure 4, which is shown in the figure. The waveform abnormality diagram is taken as follows. The waveform abnormality (or omission) has a great influence on receiving or transmitting the digitized signal. The waveform abnormality (or omission) is caused by the digital signal demodulated by the optical coupling receiving component 10, and the original signal is transmitted. The digital signals are different, which causes the digital information to be erroneous or damaged. Therefore, the manufacturing end needs to perform related electrical inspection on the packaged optical coupling receiving component 1〇. Measure 'to improve the product yield at the time of shipment, and 'the existing detection methods mostly drive the optical coupling receiving element 1 〇 to be in a stable working state, and the optical coupling receiving element 1 〇 continuously receives the signal at a detection time when detecting At the end of the time, by detecting whether the signal received by the optical coupling receiving component during the detection time has the occurrence of the above two situations, it is known whether the two working voltage sources (Avdd and Dvdd) are disconnected after the package is encapsulated. Although it can improve the product shipment yield, it will lead to a decline in production capacity, and the manufacturing side needs to open a new inspection station for testing. Therefore, if the detection process can be appropriately improved, it will improve the detection and lead to the reduction of production capacity. The situation.

After the actuation, a shock waveform is generated. At this time, the electrical parameter referred to in the present invention is the above-mentioned 2 Sasser wave • shape 'by measurement module 203 and to be tested The output pin Out of the component 21 is electrically connected to measure the oscillating waveform generated by the component 21 to be tested; (4) determining whether the component to be tested generates 瑕疵34: according to the above, the measuring module 203 measures the same The oscillating waveform is transmitted to the frequency detection module 2 0 4 ' for frequency detection. Please refer to "Fig. 8". The figure shows the detection result of the invention (1). The module 204 compares the oscillating waveform generated by the good product to compare the oscillating waveform generated by the component 21 to be tested, and whether it is different from the oscillating waveform of the good product to determine whether the device under test 21 is generated after the chip packaging process. As shown in the figure, the amplitude (or frequency) of the oscillating waveform W1 generated by the good product is different from the amplitude (or frequency) of the oscillating waveform W2 generated by the defective product.

In the righteousness, or before the test, the oscillating frequency is measured in advance for the good product, as the basis of the comparison', and the oscillation frequency generated by each of the elements 21 to be tested is not the same, so when comparing the oscillation frequency, A flexible mechanism can be further constructed to reduce the occurrence of misjudgments. As described above, the above embodiment uses a voltage source as the detection source D1 to drive the device under test 21 to generate an action, and transmits the oscillation frequency of the device under test 21 to determine whether or not a wire break occurs. However, In addition to the above embodiments, the present invention can further make the detection source D1 a specific frequency of the optical signal. Please refer to the "figure 9", which is shown in the figure of the present embodiment. The implementation flow of the above embodiment is as follows: (1) The device under test is in an unstable working state 41: This step is the same as the operation of the device under test in the unstable working state 31 step.

The measured oscillating waveform has a relatively high frequency, so that the component 21 to be tested of the oscillating waveform W4 is measured as a product, and the component 21 to be tested of the oscillating waveform W3 is measured as a good product. The invention can quickly determine whether or not the component to be tested 21 is broken.
