LED encapsulation is to provide the LED
chip electricity, light, heat on the necessary support. For example,
prolonged exposure to semiconductor components in the atmosphere will
be subject to moisture or other environmental effects of chemicals in
the aging, resulting in characteristic recession. Use a highly
transparent epoxy resin-coated light-emitting diodes, is an effective
method of isolation from the atmosphere. In addition the types of
substrates can provide adequate mechanical protection of LED
components, so that LED's reliability has increased significantly.
Currently mainly used for LED substrate, with wire rack, metal
substrates, low-temperature co-fired ceramic substrate, etc., of which
the low-temperature co-fired ceramic substrate of the thermal expansion
coefficient and the closest the semiconductor, which provides a highly
reliable LED substrate.
