RT series is a supporting tape used in the map molding process of QFN and SON. Attaching on the reverse face of a lead frame, it has achieved no flush burr after molding and high productivity in wire bonding. The applications has been expanded to new packages besides QFN and SON.

• Thermoplastic resin with high thermal stability for adhesive layer.
• Good wire bondability.
• No flash burr after molding.
• No adhesive on lead frame after detaping.
• Low adhesiveness of the tape at room temperature achieves no dust attachment.
