Abstract

PURPOSE:To contrive the improvement of reliability of the electrical connection between an electronic component and external connecting terminals by a method wherein a conductive circuit on a tape carrier is electrically connected with the external connecting terminals through through holes. CONSTITUTION:An electronic component mounting substrate is constituted into a structure wherein a lead frame, which consists of a tape carrier 4 with a conductor circuit 3 formed on its surface, an island 8 and external connecting terminals 5, is integrally formed with a base material layer 7 in a form that it is pinched in the layer 7 with the layer 7, the circuit 3 on the carrier 4 is electrically connected with the the terminals 5 through through holes 6 and the terminals 5 project from the layer 7 to the outside. Accordingly, as the connection between the circuit 3 and the terminals 5 is not a connection through a low-melting point metal like a connection, which is performed using a solder or the like, the reliability of the electrical connection of the circuit 3 on the carrier 4 with the terminals 5 becomes a sufficiently superior one. Thereby, the substrate is superior in the reliability of the connection between an electronic component and the terminals 5 and a high-density mounting becomes possible.

BACKGROUND ART Conventionally, various types of electronic component mounting substrates or devices using electronic component mounting substrates have been developed and proposed. Among these, electronic component mounting boards using so-called tape carriers, in which electronic components are directly mounted on a part of the conductor circuit on a flexible board, have a pattern pitch of 2, which cannot be obtained with a rigid board.
Since it is possible to form conductor circuits with a very fine pitch of 00 μm or less, various tape carriers have been proposed as small, multi-bin electronic component mounting boards.

(Problem to be Solved by the Invention) However, if the above basic configuration is adopted, the external connection terminals between the electronic components and the electronic component mounting board, which are particularly required for high-density and multi-bin electronic component mounting boards, cannot be met. This creates an issue that must be resolved regarding the reliability of the electrical connection with the device. In other words, the connection between the conductor circuit on the tape carrier and the conductor circuit on the electronic component mounting board is made using bumps made of gold or the like used to connect the previously connected electronic component and the conductor circuit on the tape carrier. Electrical connection is usually made using solder or the like, which has a melting point lower than the bonding temperature. Therefore, due to heating when electronic components are sealed with resin, heating when mounting an electronic component mounting device obtained by placing electronic components on an electronic component mounting board, etc., on a circuit board, the electronic component mounting board Since these devices are exposed to temperatures near the melting point of solder, the reliability of the electrical connection between the electronic components and the board for mounting the electronic components was insufficient.

[Claims] The inner end of a lead frame is sandwiched and integrated between base material layers located on both sides thereof, and a conductor circuit formed in a part thereof and electrically connected to an electronic component is integrated into the lead frame. In the electronic component mounting board which is connected to the side, the conductor circuit is formed on the upper surface of the base material, and the conductor circuit and the base material partially overlap with the inner end of the lead frame. a tape carrier sandwiched between the two base material layers together with a lead frame; an opening formed in the base material layer to open a part of the conductor circuit on which the electronic component on the tape carrier is to be mounted; and the lead. A through hole is formed to penetrate the base material layer located on both sides of the frame and the base material on the tape carrier side, and electrically connects the conductor circuit of the tape carrier and the inner end of the lead frame. A board for mounting electronic components, which is characterized by:
