Silver epoxy is more cost-effective and used more frequently but copper conductive epoxy is far better in terms of thermal conductivity. However, both will improve the quality of current conduction between the vias and the PCBs internal layers. It should be noted that conductive fill of vias is...
The KGD is attached to the FlexPCB using epoxy, whereas the die pads are aligned with the PCB pads. A silver paste is printed onto the aligned pads to bond the pads electrically and mechanically through the OEP assembly method as described below. The PCB traces connect the die pads to an...
Generally, the non-conductive variants are a better bet for the CTE’s value matching. This is because they provide a more reliable overall structure for matching the CTE to the laminate. On the other hand, despite the widespread adoption of the non-conductive epoxy; the conductive variant ...
Non-Conductive Via Filling (NCVF) enhances PCB reliability by preventing solder wicking, providing structural support, and improving longevity and stability of vias and pads.

To enable bending of the nonstoichiometric 2D Cr1+σSe2 nanoflakes transferred on polyimide (PI), the electrodes were connected out to 0.1 mm Cu wires by high-conductive silver glue (H20E, Epoxy Technology). The electrical measurements were done on a probe station system with a Keithley ...
a conductive bump protruding from and electrically connecting to the second surface of the substrate; a second die, larger than the first die, comprising an active surface electrically connecting to the conductive bump; an underfill disposed between the second die and the second surface of the subs...
In the IC chip/substrate assembly, the non-conductive adhesive may be a thermoset polymeric adhesive, or an epoxy-type adhesive. The dummy bumps may be formed of copper or aluminum. The dummy bumps may be formed in-between the bumps or the bond pads occupying between about 1% and about 10...
