Lamination process

Lamination technology is used for various industries such as semiconductor packing, office automation equipment and decorative parts etc.

High-adhesive process is needed in various fields such as electronic industry now. We are able to advise from the adhesive material type to process for the customers based on our wide experiences. We will support from FAI to mass production to meet customers requirement.

Adhesive tape lamination on heat sink

Heat sink attachment on power leadframes is now required to increase heat dissipation, and adhesive is needed on heat sink. We can advise adhesive tape properties and thickness, and supply it as laminating parts. In case of using thermosetting adhesive tape, we process it under a nitrogen atmosphere and supply it as laminating parts having reflow resistance.

Adhesive tape lamination for semiconductor PKG

Exothermic issue is occurred by increasing pins of leadframe for semiconductor PKG. It is necessary to attach a heat sink on circuit board to avoid this issue, and adhesive tape with high heat resistance is required. We perform from punching process for making adhesive tape shape to lamination process to attach heat sink or circuit board. We have cold storage system ( below 5 ℃）for the adhesive tape needing cold storage.

PI backside tape lamination

QFN backside tape is necessary for QFN molding process. Our company can provide tape lamination using various tapes with different makers such as adhesive, thermoset, and thermoplastic tapes. We can accept tape lamination not only our etching leadframe but also customer’s supplied leadframe.
