Published process guide articles across applications, materials, and technical topics.
Binder-particle refractive-index contrast influences scattering, while wetting, cure, coalescence, shrinkage, and void formation determine whether a uniform optical path survives into the finished NIR-control film.
Matching Polymer, Activator, Laser Wavelength, Power, Speed, Focus, and Hatch Strategy — a method-conditioned engineering guide for LDS/MID covering structure-function behavior at the material, interface, and finished-system boundary, process limits, validation, and qualification boundaries.
Qualify the complete metallization stack and both interface histories, because cleanliness, oxide, finish, thickness, topography, preparation, storage, wetting, reaction, contact area, and failure location jointly control package adhesion and contact resistance.
Milling should break performance-limiting agglomerates without adding media or liner wear, overheating the batch, changing surface or phase chemistry, or shifting the cured film's spectrum and color.

A mixing-development method that balances incorporation and deagglomeration against morphology damage, heat, air entrainment, rheology drift, and loss of the finished thermal path.
Addition order controls which surfaces are wetted first, which species occupy them, local solids and viscosity, deagglomeration efficiency, binder development, air entrainment, and final distribution; select the sequence through controlled stage-by-stage evidence rather than a universal recipe.

High-shear mixing must open bundles and distribute phases without unacceptable CNT shortening, platelet fracture, aggregate change, heating, contamination, air, or later network loss; define the window with interruption-state morphology and processed-electrode results.
A two-stage compounding and molding control plan that balances CNT wet-out and bundle reduction against tube damage, flow orientation, and loss of finished-part ESD continuity.
Choose pressureless or pressure-assisted processing from the package temperature, stress, geometry, throughput, contact, pore, interface, and reliability window—not from a nominal peak temperature or coupon density alone.
Pressureless vs Pressure-Assisted Sintering for Die-Attach Assemblies — a method-conditioned engineering guide for Silver & Copper Sintering Die-Attach Materials covering structure-function behavior at the material, interface, and finished-system boundary, process limits, validation, and qualification boundaries.
Agglomerates, streaks, pinholes, and nonuniform weight can arise at different slurry, transfer, filtration, coating, substrate, gas, contamination, or drying stages; localize the first appearance and preserve filter, position, time, and dry-electrode evidence before changing formulation.
