Description
Silver Conductive Adhesive Paste
Surface Curing: 60℃~100℃ (20-40 min); Room Temperature (2~5 Hours)
Silver conductive adhesive is an engineered solution designed for advanced electronic packaging and interconnect technologies where high thermal reliability and superior electrical signal integrity are paramount. Formulated with a high-density silver filler matrix, the paste exhibits an optimized rheological profile suitable for high-precision dispensing, ensuring uniform bond lines and void-free interfaces. Its hallmark feature is the mild-temperature curing kinetics, which allows for robust cross-linking without compromising the structural integrity of heat-sensitive substrates or delicate semiconductor components. By balancing high mechanical shear strength with low volume resistivity, this conductive adhesive provides a reliable, long-term solution for demanding microelectronic environments subject to thermal cycling and mechanical stress.
