Die Attach: Electrically Conductive Adhesives

Conductive adhesives are the perfect solution for mounting temperature-sensitive chips on smart cards, as their curing temperatures lie clearly below soldering temperature. In addition these adhesives are much more flexible than solder and are therefore better able to withstand bending of the smart card. A further advantage over soldering is that conductive adhesives are lead- and solvent-free.

With its Elecolit^® range Panacol offers a broad spectrum of electrically conductive adhesives suitable for die attach applications. The adhesives are one-component adhesives and can be simply applied with dispensers. Curing is either thermal at 120 to 150°C or through exposure to UV light.

Electrically conductive adhesives are the perfect choice to mount chips and dies
