Abstract
Abstract PURPOSE:To suppress the advancement of silver migration by lengthening the surface distance of a solder resist between adjacent silver jumpers. CONSTITUTION:Through holes 2 are formed on specific positions of an insulating sheet 1. Circuits 3 and lands 4 are formed on the insulating sheet 1. The circuits 3 are coated with a solder resist 5. The through holes 2 are filled up with a silver paste 6 to form silver through holes 7 whose outer surfaces are coated with a silver overcoat 8. Finally, multiple insulators 9 are formed on the silver resist 5.
