Printable films

Combines film and paste adhesive features

ABLEFLEX(R) 6200 series printable films, used in flex or laminate based packages, are B-staged before die-attach and cure, and may be pre-applied to substrates or a wafer's backside. Meeting the tight tolerances of 3D packaging, the films feature reportedly good bondline, fillet, and flow, as in a preform film. Like a paste adhesive, films have void-free bondlines without substrate pre-dry, due to surface topography on laminate and flex. Ablestik Laboratories, www.ablestik.com Enter 654
