Chip carrier for electronic element

Abstract

Abstract PURPOSE:To ensure the resin sealing of a chip for electronic parts and to make it possible to attach straight terminal pins with the protruded size being constant, by hardening a resin for sealing the chip for electronic parts under the state the resin is surrounded by a resin hole for insulating plate. CONSTITUTION:An insulating plate 4, in which a resin sealing hole 2 and pin holding hole 3 are provided, is laminated on a printed wiring board 1. An electronic part chip 5 is mounted on the surface of the printed wiring board 1 in the resin sealing hole 2. The electronic part chip 5 is sealed with a sealing resin 6 filled in the resin sealing hole 2. The base parts of terminal pins 7 are inserted and fixed in the pin holding holes 3. Therefore, flowing resin 6 is stopped by the resin sealing hole 2 in the insulating plate 4, which is laminated on the printed wiring board 1. The terminal pin 7, which is inserted in each pin holding hole 3 in the insulating plate 4 hits the surface of the printed wiring board 1 at the bottom of the pin holding hole 3. Thus the insertion depth of the terminal pin 7 is regulated.
