A card is fabricated by fixing together multiple boards. By fabricating a card from multiple boards, the reliabilities of the individual boards may be tested independently. Failure of a single board component may not, for example, result in failure of a card so long as the reliability of a single board is determined before the single board component is fixed to the other board component(s).

The invention discloses a automatic chip testing method, which is characterized by comprising the steps that: the system is powered on, and initialization is completed; the configuration is carried out, a test thread needs to be started is determined according to chip types, and an instrument transceiving end is configured; a test command is generated, test items and test parameter setting in a chip integrated test case configuration file are read and analyzed, and a command frame is generated and transmitted to a single-board system through a communication interface; and the command is analyzed, and setting and testing steps are carried out. The automatic chip testing method can achieve the automatical test and data storage of chips, can be used for testing the chips quickly, is high in test efficiency, saves test time to a certain extent, can achieve the purposes of automatic configuration of a tested DUT chip, automatic configuration of instruments, automatic recovery of test results and automatic generation of test reports, automatic generation of test case reports and automatic switching of test cases through the development of an automatic chip testing platform.

The invention comprises an electronically secured inter-processor and virtual device communications system, with an input / output controller board, a multi-drop bus interface to multiple devices, and a parallel interface to an industry standard single board computer. The invention assigns a bus address and virtual identification number to each device and controls communications between the main central processing unit and the devices through a Plug-n-Play protocol.

The invention provides a single-board integrated LED (light-emitting diode) dot-matrix module which comprises a circuit board and a dot-matrix circuit which is at least a 16*15 single primary color SMD (surface mounted device) LED dot-matrix circuit, wherein the dot-matrix circuit is arranged on a main view face of the circuit board and used for displaying information, a control circuit and a power interface are arranged on a rear view face of the circuit board, the control circuit is respectively connected with the power interface and the dot-matrix circuit, the power interface is used for connecting a power supply used for supporting the operation of the control circuit and the dot-matrix circuit, the control circuit is used for controlling LEDs in the dot-matrix circuit to display the information according to requirements of edited or modified display contents according to operation data received or typed by the control circuit. According to the invention, through the control circuit and the power interface which are arranged on the module, the problem that a module in the prior art needs an additional editor and an additional display controller can be solved, therefore, the use condition of the LED dot-matrix module is simplified effectively, and the module can display information and the displayed contents can be edited and modified by virtue of an infrared remote controller or operational keys after the power interface is connected to the power supply.

The embodiment of the invention provides a dormancy method for a server. The server comprises a system management board and at least one single board, wherein each single board comprises an intelligent management controller. The dormancy method for the server comprises that: the system management board receives a dormancy signal transmitted by a remote host computer; and the system management board transmits the dormancy signal to the intelligent management controller of the corresponding single board so as to cause the intelligent management controller of the single board to control the single board to enter a dormant state according to the dormancy signal. The embodiment of the invention also provides a wakening method for the server, and the server with a dormancy / wakening function. Theintelligent management board of the single board controls the single board to enter the dormant / wakened state according to the received dormancy / wakening signal, so the embodiment of the invention realizes the dormancy / wakening function of the server, and can make the single board of the server consume less electric energy when the load is relatively lower, effectively save the energy consumption, and when the traffic is boosted, quickly waken the single board of the server to share the load.

The invention discloses an allocation method for veneer groove location numbers and comprises the following steps that a central veneer receives address request messages sent by a business veneer; the central veneer allocates groove location numbers for the business veneer according to the corresponding relationships of preset interface numbers, groove location numbers and the interface numbers of the received address request messages; the central veneer returns and carries responding messages of the groove location numbers to the business veneer. The invention also correspondingly provides a central veneer, a business veneer and a communication system. The adoption of the technical proposal provided by the embodiment of the invention ensures the accuracy of the allocation of the groove location numbers and the stability of the communication system.

The invention discloses a backboard system, relating to the technical field of communication and used for reducing the limitation of a heat radiation framework. The backboard system is applied to network equipment and comprises a plurality of backboards, wherein a plurality of slots for connecting single boards are formed on the edge of each backboard; each slot on the same backboard is used for connecting the different single boards; and each slot on each backboard is used for connecting the same single board.

A printed circuit board (PCB) is provided. The PCB includes a first microwave board material, a second prepreg, and a third ordinary board material that are pressed together. The first microwave board material, the second prepreg, and the third ordinary board material are provided with an opening respectively. At least two openings have different sizes. In a region between boundaries of the at least two openings having different sizes, a borehole is provided to pass through the board material in the region. A back-drilled hole is selectively used. A radio-frequency device and a method for manufacturing a PCB are further provided. Thus, it is suitable for designing different power modules and other circuit modules on the same single board, and is compatible with the existing basic PCB manufacturing technologies, which further has a low cost, and can meet the requirements of large-power radio-frequency circuits with different frequencies.
