Title:
MEASURING/CORRECTING METHOD FOR MODULE SUBSTRATE AND JIG FOR THE SAME
Document Type and Number:
Japanese Patent JP3957822
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To accurately measure and correct the electric characteristics of modules on a module substrate with a jig not bulky and having a good shielding property of electric noise.
SOLUTION: Modules 1a having electric characteristics are vertically and horizontally arranged on a module substrate 1, module 1a areas are partitioned and surrounded by shielding walls 3a shielding electric noise in both the vertical arranging direction Y and the horizontal arranging direction X on the mounting face 1b of the module substrate 1 where electric characteristic members 4, 5 are mounted, and the electric characteristics of the modules la in enclosures are measured and corrected.
