Abstract

PURPOSE:To enable one side of a hexagon to be positioned to a terminal for connection and eliminate a problem where a lead falls even if a TAB tape is inverted by creating a lead by etching from both sides and by forming a TAB-IC using the TAB tape where a lead section is in hexagonal form. CONSTITUTION:A TAB tape 1 and a lead 2 which is connected to a terminal for connection 3 of an IC 4 being extended from this TAB tape 1 where the section is in hexagonal form are provided. The lead 2 is formed in hexagonal form by etching from both sides of the tap. Namely, the TAB tape 1 has the lead 2 whose section is in hexagonal form and position matching between this lead 2 and the terminal for connection 3 is performed and ILB is performed for constituting the TAB-IC. Even if the TAB tape 1 is inverted or the lead 2 falls, one side of the hexagon is always position-matched to the terminal for connection 3, thus constantly achieving ILB under constant conditions.

トを起こすという欠点や、接続も完全に行なわれないと
いう欠点があった。``The conventional TAB-IC described above has a trapezoidal cross section because it is made by etching the leads of the TAB tape used or from one side of the tape. Therefore, when connecting to the connection terminal of an IC, if you align the narrow side of the lead cross section and perform ILB, the lead becomes unstable and falls over as shown in Figure 5. It had the disadvantage of causing a short circuit with the terminal and the disadvantage of not making a perfect connection.

ばならなかった。Also, when performing ILB by reversing the TAB tape and aligning the wide side of the lead cross section, problems such as the lead falling over will not occur, but the load per unit area applied to the IC connection terminal during ILB will change. , ILB conditions had to be set separately.
