Disclosed is a method of coating a conductive substrate with an adhesive, wherein the amounts and positions of conductive and non-conductive adhesives for bonding a plurality of circuit elements to the conductive substrate are set, thus preventing the spread of the adhesive from causing defects, including a poor aesthetic appearance, low electrical conductivity, and short circuits.

A semiconductor package is disclosed. The semiconductor package comprises a lower package including a first substrate and a semiconductor chip on the first substrate, a second substrate on the lower package, interconnect terminals between the first substrate and the second substrate, and an adhesive pattern between a top surface of the semiconductor chip and a bottom surface of the second substrate. The adhesive pattern extends along an edge of the semiconductor chip. The adhesive pattern exposes a top surface of a central zone of the semiconductor chip.

An electronic component mounting method including the steps of: providing a first electronic component having a principal surface provided with a plurality of bumps; providing a substrate having a placement area provided with a plurality of first electrodes corresponding to the plurality of bumps; applying flux to the plurality of bumps; applying flux to at least one of the first electrodes adjacent to at least one reinforcement position set on a peripheral portion of the placement area; dispensing a thermosetting resin onto the reinforcement position, and at least partially coating the first electrode adjacent to the reinforcement position, with the thermosetting resin; placing the first electronic component on the substrate such that the bumps land on the corresponding first electrodes, and thus bringing the thermosetting resin into contact with a peripheral edge portion of the first electronic component; and heating the substrate with the first electronic component placed thereon.

A radar device includes: a substrate including multiple high-frequency conductor layers arranged on a front surface; a semiconductor component in contact with the high-frequency conductor layers via conductive members; and an adhesive that bonds the semiconductor component to the front surface of the substrate. The semiconductor component has a bottom surface and a first side surface facing in a first direction. All the multiple high-frequency conductor layers include at least high-frequency conductor layers bending in a plane of the front surface and thereby extend, on the front surface, from inside ends facing the bottom surface to outside ends positioned in the first direction from the first side surface. The adhesive is in contact with the front surface except for the sites of the multiple high-frequency conductor layers formed and in contact with the side surfaces of the semiconductor component.
