TERMINAL LAND OF HYBRID INTEGRATED CIRCUIT

摘要

PURPOSE:To prevent solder from covering over a through hole and to realize stable quality by providing a slit to a terminal land which is made around the through hole and by applying an overcoat of solder onto the terminal land. CONSTITUTION:As a pattern structure of a terminal land 3 of a hybrid integrated circuit, a slit 6 is provided to the terminal land which is made around a through hole 1, and an overcoat of solder 4 is applied onto the terminal land. The slit provided to the terminal land prevents the solder from covering over the through hole, thus applying an overcoat of solder onto the terminal land alone.
