Zusammenfassung: | PURPOSE:To obtain an I/F substrate commonly applicable to both a surface system and a rear system. CONSTITUTION:Ground reinforcement patterns 1a, 1b are formed around through holes 5a, 5b, so as to be isolated from a ground surface 3. A foot pattern 9a of an IC socket 8a for a surface system which foot pattern 9a is to be connected with a ground pin 7 of an IC is inserted into the through hole 5a. A foot pattern 9b of an IC socket 8b for a rear system which foot pattern 9b is to be connected with a ground pin 7 of the IC is inserted into the through hole 5b. |
