Application Summary AI generated
GB/T 28859-2012 specifies the technical requirements, test methods, inspection rules, and packaging/storage conditions for powdered epoxy encapsulating materials used in electronic components. It is applied in the manufacturing of capacitors, resistors, inductors, and other passive components where the powder is electrostatically sprayed or fluidized-bed coated to form a protective insulating layer. The standard ensures consistent performance in moisture resistance, electrical insulation, and thermal stability during component assembly and operation.
