Anti-Sulfuration Application
Anti-sulfuration memory modules are mainly used in equipment exposed in
highly contaminated environment, e.g. automobile, military, medical, transport,
networking and outdoor electronic products, and electronic equipment used in
areas of high-concentration sulfur gas, e.g. volcano, hot spring and mine.
Airborne sulfur-containing particles can easily react with silver used in the
electrode to form silver sulfide which is non-conductive. As sulfuration
increases, resistance value will also increase, eventually causing an open
circuit. To solve the problem of resistor sulfuration, Apacer has developed the
world’s first anti-sulfuration memory module for use in a sulfur-rich
environment and this innovative design is now patented.
