[0002] The current test environment is built in such a way that the pogo-type universal board on the T5830ES is connected to the adapter board through spring pins, and the adapter board is connected to the cable board through a connector. The cable is welded to the cable board using welding technology, and the cable board needs to use an additional mechanical support frame to support the connection and leveling of the cable connection board and the adapter board.

This design is an improvement on the original design system, making it more applicable and less costly. Utility Model Content

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0021] See also Figure 1-2 As shown, the purpose of the present invention is to provide a PCB board of a universal connection board to solve the problems raised in the above background technology.

[0022] To achieve the above-mentioned purpose, the utility model provides the following technical solution: the positions of the six resource modules in the adapter board correspond one-to-one to the resource modules in the pogo-type universal board (H7-912591), and the adapter board uses six high-density high-speed connectors corresponding to the six resource modules and is close to the resource modules corresponding to the pogo-type universal board (H7-912591), and adopts an orderly arrangement to achieve the consistency of the signal of each module.

[0023] Moreover, the positions of the common signal pads, power pads, control signal pads, and SENSE pads in each connector are consistent. Even if the connector is plugged in incorrectly, the power signal and the ground will not be short-circuited, thereby not burning the device or board, ensuring its safety and practicality.

[0024] The specific plan is: this universal adapter board is a 24-layer PCB board, which is divided into a top layer, a signal layer, a programmable power supply PPS layer, a power layer, a ground layer and a bottom layer.

[0025] The bottom resource module is connected to the pogo-type universal board (H7-912591) of the T5830 test system. The top board is connected to the product test board through a connector, and the test board is then connected to the chip to be tested, thus forming a closed loop for wafer testing or post-packaging testing.

[0026] From the perspective of the top board, the bottom board includes six resource modules. The left half is resource modules 1, 2, and 3 from top to bottom, and the right half is resource modules 4, 5, and 6. Each resource module has 48 signals, 8 groups of power supplies and their corresponding 8 groups of power sense, as well as other control signal pads or high-voltage power pads. Each group of power supplies has a solder point near the connector end for soldering power bypass capacitors, which can adjust the capacitor parameters over a wider range according to the power requirements of different test environments.

[0027] The power supply is evenly distributed, which can be applied to the testing of different chips, improving the efficiency and versatility. The top board includes 6 connector pads, which are used to solder the connectors, and then connected to the test board through the cable. A and B characters are added on both sides of the connector as the installation direction of the connector to better guide the operator and avoid the misoperation of plugging the connector in the wrong direction. The connector itself also has a foolproof device to prevent reverse plugging.

[0028] The programmable power supply on the resource module is connected through copper foil, and the programmable power supply PPS and its corresponding Sense line are on the same layer, which improves stability.

[0029] The ground layer is divided into the ordinary GND layer and the GND2 layer.

[0030] The PPS power signal, common signal and control signal refer to the common ground layer, and the power layer refers to the GND2 layer.

[0031] The signal layer and the signal layer, the signal layer and the PPS layer, the PPS layer and the PPS layer, and the PPS layer and the power layer are all separated by the reference ground layer, thereby reducing the power crosstalk problem and ensuring the integrity of the power supply.

[0032] The exposed pads on the top layer board must be insulated to avoid short circuits caused by metal objects placed on the front.

[0033] The signal lines are all made of equal length, and the same structure is produced by replication, which can eliminate the problem of signal asynchrony at the board level. The line spacing between signal lines is kept at more than 5 times the line width, eliminating mutual interference between signals.

[0034] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
