TAB Band und sein Herstellungsverfahren

摘要

A TAB (tape automated bonding) tape of high precision is formed by providing a metal support (10) and adhering a conductor pattern (20) to it by an electrically insulating adhesive (12). Such a tape does not deform and can be hermetically sealed with resin. A method for producing such a TAB tape includes punching required holes, such as a device hole (14) in a metal plate (10) coated with an insulating adhesive layer (12) over the area where a conductor pattern is to be formed; and forming a required conductor pattern (24) by bonding a conductor metal foil onto the adhesive layer and etching the conductor metal foil. The material cost of this TAB tape is less and the production is facilitated.
