Abstract
An adhesive bonding laminate includes a first adhesive film that is capable of adhesively bonding to an epoxy coating and a second adhesive film that is capable of adhesively bonding to a stainless steel substrate. The first adhesive film is adhesively bonded to the second adhesive film. Ink jet printheads, ink jet print cartridges and methods of attaching a flexible circuit to a substrate employ the adhesive bonding laminate.
Claims8
