Abstract
PURPOSE:To prevent IC breakage due to electrical change thereof caused by the friction between an IC bottom and an IC case bottom by providing a wedge- form projection in contact with the bottom of IC which is placed on the bottom inside the IC case. CONSTITUTION:An IC case 1, having a wedge-form projection 11 at the bottom in the section, is a body of a rectangular tubular bar made of synthetic resin. DIP type IC 2 is in contact with only the wedge-form projection 11 at the bot tom of the IC case 1, when the IC 2 is taken out, it causes friction only against the contacting part of the wedge-form projection 11. Therefore, electrical charge caused by friction is rarely brought about and also IC is not broken by electrical discharge.
