- the software that emulates the memories 33 and 34 in the inspection device 603 or the inspection device 603 It is conceivable that the memories 33 and 34 are mounted on the evaluation board 601, the inspection board 602 or the socket 501. These memory functions and the module substrate 232 are connected to transfer signals from the LS 132 to the memories 33 and 34, and the waveform and pattern of each transferred signal can be inspected.
- an inspection signal is input to the LSI 32 from the inspection device 603 external to the module board 232 and output from the LSI32. It is necessary to match the expected signal with the expected signal.
- the inspection terminals 241 and 242 and the wiring patterns 111 and 112 are electrically connected. Accordingly, by connecting the inspection device 603 to the inspection terminal 241 or 242, it is possible to use the force S to detect the waveform and pattern of the address signal and the clock signal transferred from the LSI 32 to the memory 33.
- the inspection terminal 243 and the wiring pattern 115 are electrically connected.
- the inspection device 603 to the inspection terminal 243, the waveform and pattern of the data signal transferred between the LSI 32 and the memory 33 can be inspected.
- the inspection terminal 244 and the wiring pattern 116 are electrically connected.
- the inspection device 603 to the inspection terminal 244
- the waveform and pattern of the data signal transferred between the LSI 32 and the memory 34 can be inspected.
- the inspection terminals 241, 242, 243 and 244 and the inspection device 603 are connected.
- the inspection signal can be input to the inspection terminals 241, 242, 243, 244, and the signals output from the inspection terminals 241, 242, 243, 244 and the expected values can be collated.
- the inspection terminals 241, 242, 243, and 244 are provided on the second substrate 12.
- the external substrate 201 of the television receiver according to Embodiment 2 eliminates the need to provide lands corresponding to the inspection terminals 241, 242, 243, and 244. Therefore, the module substrate 232 and the module substrate 233 are provided. The area required for mounting the connected finished product can be reduced by the area of the inspection terminals 241, 242, 243, and 244. As a result, the small size of the television receiver Can be realized.
- the inspection terminals 241, 242, 243, 244 also serve as connection terminals for connecting the module substrate 232 and the module substrate 233. Therefore, an extra inductive load or a capacitive load added to connect to the external substrate 201 or to an extra inspection terminal and a wiring for drawing out to the inspection terminal can be eliminated. That is, waveform distortion of the address signal, clock signal, and data signal transferred between the LSI 32 and the memories 33 and 34 can be suppressed, and high-speed operation can be achieved. As a result, it is possible to improve the performance of the television receiver.
- the inspection terminals 241, 242, 243 and 244 can be electrically connected to the inspection device 603. Further, the software 33 for emulating the memories 33 and 34 in the inspection apparatus 603, or the memories 33 and 34 can be mounted on the inspection apparatus 603, the evaluation board 601, the inspection board 602, or the socket 501. As a result, it is possible to inspect the waveforms and patterns of all data signals transferred between the LSI 32 in the module substrate 232 and the memories 33 and 34. When the internal circuit of LSI32 is inspected, an inspection signal is input from the inspection terminals 241, 242, 243, 244, and the signals output from the inspection terminals 241, 242, 243, 244 and expected values And can be matched. As a result, the waveform and pattern of all data signals transferred between the LSI 32 inside the module board 232 and the memories 33 and 34 can be inspected and the expected values collated, thereby improving the quality of the module board 232. That's the power S.
- the lands corresponding to the test terminals 241, 242, 243, and 244 of the module board 232 are provided in the evaluation board 601 in the manufacturing factory of the manufacturer that manufactures and ships the module board 232. Necessary force It is not necessary to provide the external board 201 of the product using the finished product connected with the module board 232 and the module board 233. Therefore, the module board 232 is required for the board after shipment from the manufacturer's manufacturing plant. Since the number of necessary lands can be reduced, the area required for mounting can be reduced. That is, the module substrate 232 has the same effect as being able to reduce the size of the manufacturer's manufacturing factory after shipment by using the inspection system including the socket 501 according to the second embodiment. In addition, since sufficient inspection can be provided while having the effect of downsizing, there is an effect that both cost reduction that prevents an increase in manufacturing cost and quality improvement that can reliably inspect electronic components can be achieved.
- the module board and socket, and the inspection system using them which are effective in the present invention, have the same effect as being able to be miniaturized after shipment at the manufacturer's manufacturing plant.
- the module substrate and socket and the inspection system using them that are effective in the present invention are useful as a module substrate on which electronic components are mounted, a socket for storing the module substrate, a system for inspecting electronic components, and the like.
