We performed kinetic analysis in an epoxy curing system with differential scanning calorimetry (DSC) using a dynamic approach to investigate the reaction behavior of epoxy molding compounds (EMCs) according to three types of catalysts with varying latencies: triphenyl phosphine (TPP), triphenylphosphine‐1,4‐benzoquinone (TPP‐BQ), and tetraphenylphosphonium tetraphenylborate (TPP‐TPB). In dynamic approach,...
By changing curing accelerator and modifying the volume resistivity of epoxy molding compound (EMC), electrostatic characteristics of EMC applied package can be improved and electrostatic damage of IC device was reduced. EMC with phosphonium salt accelerator results in much lower ESD failure than EMC with phosphine salt accelerator. Because the volume resistivity of phosphonium salt applied EMC is...
A new and simple method to prepare three-dimensional (3D) graphene foams is developed. It uses 3D Ni nanowire foams as a catalyst for chemical vapor deposition (CVD). Ni nanowires were synthesized on a large scale by the reduction of Ni ions under an applied magnetic field, and then assembled into a 3D film by filtrating a bulk Ni nanowire solution or by pressing Ni nanowire powder. An additional...
Upon the addition of silver nanowires (AgNWs), the electrical conductance of graphene film is improved. According to the film's optical birefringence, as shown by studies using liquid crystals (LCs), the improvements do not result from the chemical doping properties of the AgNWs; instead, they arise because the AgNWs facilitate connections among the domains in the graphene film. This is further supported...
