Material Design

Material design for customer’s product and processes

: Metal / Ceramic / Inorganic Carbon / Glass / Polymer / Dispersant
: Particle Size and Its Distribution / Specific Surface Area / Density
: Type/Shape/Amount

Homogeneous dispersion of binder and organics through matching their compatibility

Better film strength and adhesion force after sintering (or curing)

: unique composition of glass and inorganic additive
: type of binder and its composition

High-temp. microscope images of Ref. glass and FM glass system

Cross-section SEM images after printing Ag pastes on AlN substrate and sintering @850℃

Stable viscosity

: good organic (binder and additive) design considering chemistry

Viscosity change of metal-epoxy pastes @25℃ for 35 days

Control of printing shape and surface roughness

: paste formulation and rheology
: printing condition
