TEST BOARD OF MULTILAYER TYPE FOR HIGH-PRECISION INSPECTION

摘要

A stacked test board for high-precision inspection is provided to enhance safety and reliability of inspection by minimizing or shielding the effect of electrical signals using a signal shield fence. A stacked test board for high-precision inspection includes plural test boards(10), spacers(20), connection cables(30), and signal shield fences(40). The test boards include plural mounting components mounted on a side thereof and input/output signal terminals at the end portions thereof. The spacers are used for arranging constantly the test boards by separating the test boards. The connection cables are positioned between the input/output signal terminals. The signal shield fences are formed up to constant height so as to prevent interference of electrical signals between mounting components on the test boards.
