Polising et microscopic propria aurea Alloy sheet coatings ad microelectronic packaging

28-05-2025

Gold alloy sheets generally refer to thin sheet materials made of gold alloy used for connecting, fixing or packaging electronic components, etc. Due to the extremely high electrical conductivity, good thermal conductivity, high chemical stability, good flexibility and ductility of gold, the surface of the gold alloy sheets is widely used in microelectronic packaging and the manufacturing of optoelectronic devices after being gold-plated.

To measure the thickness of the coating on the gold alloy sheets, they are now polished for sample preparation: Since the sample size is very small and light in weight, to prevent the sample from floating in the liquid epoxy resin, an X-type sample holder is used for fixation.
