Phosphorus Rejection Dynamics in Electroless Nickel Solder Intermetallic Phases
Phosphorus rejected during solder reflow forms brittle nickel phosphide layers that demand high-speed shear testing and strict IPC-4552 chemical control.
Finite Element Shear Failure Modeling for Latent Interface Cracking in High Temp Thermal Aging
Finite element shear modeling predicts latent interface cracking in high-temperature electronics by applying age-degraded cohesive zone parameters.
Characterizing Intermetallic Compound Formation Rates in Micro-BGA Solder Interfaces
Micro-BGA intermetallic compound formation depends on peak reflow energy and thermal aging, where excessive layer thickness causes brittle interfacial failure.
