摘要:
Reinforcement members are disposed along only the transverse edge regions of selected flexible cables of an integral chip carrier and cable assembly, and along only the respectively aligned end areas of the chip carrier portion of the assembly. The reinforcement members may be disposed along all of the flexible cables and end areas of the assembly, or on only selected cable and end area portions of the assembly. The reinforcement members are formed of a tough tear resistant polymer material, such as a hot melt adhesive or polymer tape or film.
摘要:
An integrated circuit chip carrier assembly is provided by joining a substrate having electrically conductive regions on at least one major surface thereof to a stiffener by a bonding film. The bonding film comprises a dielectric substrate having a thermoset adhesive on both of its major surfaces. The thermoset adhesive prior to the bonding is a B-stage adhesive, is tack-free at normal room temperatures and is solvent free.
