Abstract:
An electronic-component mounting structure comprising:an electronic component (2) having a surface;first electrodes (1) provided on the surface of the electronic component (2) and arranged in a first array;a base board (4);second electrodes (3) provided on the base board (4) and arranged in a second array corresponding to the first array, the second electrodes (3) corresponding to the first electrodes (1) respectively; andsolder bumps (9) connecting the first electrodes (1) and the second electrodes (3) respectively;wherein the first electrodes (1) include first outermost electrodes (1b) located in an outer area of the first array, and the second electrodes (3) include second outermost electrodes (3b, 3c) located in an outer area of the second array, the second outermost electrodes (3b, 3c) corresponding to the first outermost electrodes (1b) respectively;wherein an outer edge (X1, Z1) of each of the second outermost electrodes (3b, 3c) extends outward of an outer edge (Y1) of a corresponding first outermost electrode (1b) with respect to the first and second arrays; andwherein a distance between an outer edge (X1, Z1) of each of the second outermost electrodes (3b, 3c) and an outer edge (Y1) of a corresponding first outermost electrode (1b) is greater than a distance between an inner edge (X2, Z2) of the second outermost electrode (3b, 3c) and an inner edge (Y2) of the corresponding first outermost electrode (1b) with respect to the first and second arrays.
