Polyphenol resin crosslinking chemistry: AjinomotoRecent Research Landscape

Uncontrolled polymerization in thermosets leads to brittle failure and thermal instability. Precise engineering of the polyphenol resin composition ensures specific crosslinking densities for improved mechanical durability.

What technical problems is Ajinomoto addressing in Polyphenol resin crosslinking chemistry?

Interconnect substrate thermal instability

(10)evidences

Standard polyphenol formulations often suffer from mechanical or thermal failure after crosslinking. Improving the integrity of the cured state prevents material degradation in demanding environments.

Substrate thermal expansion mismatch

(8)evidences

Inherent brittleness and poor mechanical stability in cured phenolic networks. Improving these properties prevents premature material failure under stress.

Insufficient structural integrity

(6)evidences

Uncontrolled volumetric shrinkage and thermal expansion during curing lead to mechanical failure. Improving structural integrity prevents delamination and warping in high-performance applications.

Interlayer dielectric mechanical failure

(3)evidences

Semiconductor packaging and circuit boards suffer from mechanical failure due to mismatched thermal expansion and poor adhesion between layers. Mitigating these stresses prevents structural cracking and electrical failure.
