Detailed Description
As shown in fig. 2 to 10, taking the aging test of the bidirectional zener diode or the bidirectional tvs as an example, the embodiment of the semi-aging board with the polarity conversion device is as follows:
as shown in fig. 7, the device to be tested is a bidirectional device D, one end of the bidirectional device D is connected with the a1 end of the normally open socket interface, and the a2 end of the normally open socket interface is connected with the negative end of the power supply through the ammeter a; the other end of the bidirectional device D is connected with the b1 end of the normally-open socket interface, and the b2 end of the normally-open socket interface is connected with the negative end of the power supply through the ammeter A; the positive end of the power supply is connected with the two normally closed sockets in series and then suspended. When the normally open socket is inserted without a plug board, the interfaces a1 and a2 or b1 and b2 are open circuits, and when the normally closed socket is inserted without a plug board, the two ends of the socket interface are in closed connection.
As shown in fig. 3, for a single-station device, the sampling and reversing device board 2 is to fabricate sampling and reversing device board station electrodes 203 on a sampling and steering device board body 201, and the sampling and reversing device board station electrodes 203 are located on the bottom surface and the top surface of the sampling and steering device board body 201 and are electrically connected through sampling and reversing device board station electrode through holes 205.
As shown in fig. 5, for the multi-station device, the sampling reversing device board inserting station electrodes 203 are multiple and have the same structure as a single station.
As shown in fig. 4, for the single-station apparatus, the loading and reversing device socket 302 is formed by fabricating a loading and reversing device socket polarity electrode 303 at one end of a loading and reversing device socket body 301, the loading and reversing device socket polarity electrode 303 is located at the bottom surface and the top surface of the loading and reversing device socket body 301, and is electrically connected through a loading and reversing device socket polarity electrode through hole 306, a loading and reversing device socket station electrode 304 is fabricated at the bottom surface of the other end of the loading and reversing device socket body 301, and the loading and reversing device socket station electrode 304 is electrically connected with the loading and reversing device socket polarity electrode 303 through a bottom metal wiring.
As shown in fig. 6, for the multi-station apparatus, there are a plurality of loading reversing device plug board station electrodes 304, which are electrically connected to the loading reversing device plug board polarity electrode 303 through bottom metal wiring, and the structure of each station electrode is the same as that of a single station.
As shown in fig. 8, when the single-station sampling commutation device and the single-station loading commutation device are aligned during single-station aging, the current flow direction of the aging circuit is opposite, and the purpose of polarity commutation of the bidirectional device is achieved.
As shown in fig. 9 and 10, when the multi-station sampling reversing device and the multi-station loading reversing device are aligned during multi-station aging, the current flow directions of the batch aging circuit are integrally opposite, and the purpose of integrally reversing the polarity of the batch bidirectional device is achieved.
The mechanism of operation is as follows:
prior to the development of the present invention, a schematic diagram of a single-bit wiring circuit of a power burn-in device was shown in fig. 1. In the figure, an ammeter A is used for detecting the magnitude of current passing through a bidirectional device D, wherein D is the bidirectional device and FU is a fuse. As can be seen from the schematic diagram of the station wiring circuit, in order to change the polarity of the device D, the physical position of the device D must be changed.
As shown in fig. 7, in order to realize that the polarity reversal is realized without changing the physical position of the device D, the terminal b must be at a positive potential when the terminal a is at a negative potential; when the terminal b is at a negative potential, the terminal a must be at a positive potential. The anode and the cathode are separated, if the anode is connected with a1, b1 and b2, current flows from the a1 end to the b1 end through the bidirectional device D and finally flows to the cathode; if the anode is on b1 and a2 are connected, current flows from the b1 terminal to the a1 terminal through the bi-directional device D and finally to the cathode.
As shown in fig. 8, in order to implement the polarity reversing function, a polarity reversing device needs to be designed, the sampling device is responsible for switching on a1 and a2 or b1 and b2, and the loading device is responsible for loading a positive potential to a1 or b1. When the sampling device and the loading device are placed at different positions, the current directions are different.
The multi-station apparatus is shown in fig. 9-10, where the direction of the current is different when the sampling apparatus and the loading apparatus are placed in different positions.
In the actual use process, the polarity exchange function of the bidirectional device is realized only by exchanging the positions of the sampling device and the loading device, the polarity exchange of multiple stations is realized, the influence on the quality reliability of the device caused by the physical polarity exchange of a single-station device is avoided, and meanwhile, the working efficiency of the polarity exchange is improved.
Finally, it should be noted that: the above examples are given for clarity of illustration only, and the present invention includes but is not limited to the above examples, which are neither exhaustive nor exhaustive of all embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Embodiments that meet the requirements of the present invention are within the scope of the present invention.
