Electronic ceramic materials are a class of functional ceramics characterized by unique electrical properties, widely utilized in applications such as capacitors, sensors, substrates, and packaging components. Their maintenance and care require an approach tailored to the specific application context and material characteristics.
General Maintenance Guidelines
Avoid Physical Damage: Although electronic ceramics possess high hardness (e.g., alumina ceramics: HV 1500–2500), they are inherently brittle. Therefore, impact, collision, or concentrated localized stress should be avoided to prevent the initiation or propagation of micro-cracks.
Moisture and Static Control: Most electronic ceramics are sensitive to humidity and static electricity. For long-term storage, they should be kept in a dry environment (10°C–30°C), utilizing anti-static packaging or a desiccant cabinet.
Gentle Cleaning Methods: Surface cleaning may be performed using a soft-bristled brush, compressed air, or alcohol-soaked cotton swabs (applicable only to fully encapsulated components). The use of corrosive cleaning agents or ordinary dry cloths (which tend to generate static electricity) is strictly prohibited.
Avoid Contact with Conductive Liquids: Functional electronic ceramic components (such as substrates and filters) should be kept away from conductive liquids-such as water or alcohol-to prevent short circuits or liquid infiltration into circuit vias.
