Abstract

An electronic component has a printed substrate having a die bonding portion, a semiconductor element rigidly bonded to the die bonding portion of the printed substrate by a die bonding resin, and a wire bonding terminal formed by a conductor pattern on the printed substrate that is connected to the semiconductor element by a bonding wire. A groove portion located at a level lower than the conductor pattern of the printed substrate is formed in a region located on at least a die bonding portion side in a region surrounding the wire bonding terminal.

Claims (10)

1. An electronic component comprising:

a printed substrate comprising a die bonding portion;

a semiconductor element rigidly bonded to the die bonding portion of the printed substrate by a die bonding resin, and

a wire bonding terminal formed by a conductor pattern on the printed substrate that is connected to the semiconductor element by a bonding wire, the wire bonding terminal comprising a die bonding portion side disposed adjacent to the die bonding portion and an opposite side disposed opposite to the die bonding portion side, wherein a solder resist layer is disposed on at least a portion of the opposite side,

wherein a groove portion located at a level lower than the conductor pattern of the printed substrate is formed in a region located on at least the die bonding portion side in a region surrounding the wire bonding terminal,

wherein the groove portion is open and is configured to receive excess die bonding resin.

2. The electronic component according to claim 1 , wherein the groove portion is formed over a whole periphery of the region surrounding the wire bonding terminal.

3. The electronic component according to claim 1 , wherein the groove portion is formed by removing the conductor pattern of the printed substrate.

4. The electronic component according to claim 3 , wherein the groove portion is formed by further removing a substrate core material of the printed substrate.

5. The electronic component according to claim 1 , wherein a surface of the wire bonding terminal is subjected to Au plating.
