A method of connecting an electronic component on a mounting substrate where the electronic component is arranged with a first surface of the electronic component facing the mounting substrate and an opposite surface of the electronic component is facing away from the mounting substrate. A first component-side conductor on the second surface of the electronic component is electrically connected to a first substrate-side conductor on the mounting substrate by an electrically-conductive adhesive.

A mounting structure includes a bonding material (106) that bonds second electrodes (104) of a circuit board (105) and bumps (103) of a semiconductor package (101), the bonding material (106) being surrounded by a first reinforcing resin (107). Moreover, a portion between the outer periphery of the semiconductor package (101) and the circuit board (105) is covered with a second reinforcing resin (108). Even if the bonding material (106) is a solder material having a lower melting point than a conventional bonding material, high drop resistance is obtained.

An electronic package assembly is provided. The electronic package assembly includes a package substrate having a first surface and a second surface opposite thereto. A plurality of conductive pads is disposed on the first surface. A chip is mounted onto the first surface of the package substrate. A circuit board is mounted onto the second surface of the package substrate, and includes an electrical connector. A plurality of electrical contact components is electrically connected to the electrical connector and is in contact with the plurality of conductive pads.

Embodiments of the present disclosure are directed to a leadframe package with recesses formed in outer surface of the leads. The recesses are filled with a filler material, such as solder. The filler material in the recesses provides a wetable surface for filler material, such as solder, to adhere to during mounting of the package to another device, such as a printed circuit board (PCB). This enables strong solder joints between the leads of the package and the PCB. It also enables improved visual inspection of the solder joints after the package has been mounted.

A chip assembly may include a package substrate that includes one or more pins. The chip assembly may also include one or more pads. The one or more pads may be electrically coupled to the one or more pins. In addition, the chip assembly may include a board that includes one or more board pads. Further, the chip assembly may include an anisotropic layer. The anisotropic layer may be positioned between the board and the one or more pads and between the board and a portion of the package substrate. In addition, the anisotropic layer may mechanically couple the board to the one or more pads and to the portion of the package substrate. Further, the anisotropic layer may electrically couple the one or more pads to the one or more board pads.
