Abstract
There is provided a multilayer type test board assembly for high-precision inspection. The multilayer test board assembly comprises: a plurality of test boards separated from each other according to their functions, having input/output signal terminals, and including at least one test board each having a first section where first mounting devices sensitive to an influence of electrical signals are mounted and a second section where second mounting devices insensitive to an influence of electrical signals are mounted; spacers that arrange the test boards in parallel by spacing apart the test boards by predetermined intervals; connection cables connected to the input/output signal terminals of the test boards; and a signal shielding fence formed on each of the at least one test board so as to protect the first mounting devices from electrical signals generated by the second mounting devices.
