Guardrail light / grille aluminum plate

Circuit layer (i.e., copper) printed circuit is typically formed through etching, so that assembly of the various components are interconnected, under normal circumstances, the circuit layer requires a large current carrying capacity, and thus should be thicker copper foil thickness 35μm ~ 280μm; thermal insulation layer PCB aluminum plate is where the core technology, it is generally a special polymer made of special ceramic-filled structure, small resistance, excellent viscoelastic properties, has the ability to heat aging, can withstand the mechanical and thermal stresses . The metal substrate is an aluminum plate support member is required to have a high thermal conductivity, typically aluminum, copper can also be used (where copper can provide better thermal conductivity), is suitable for drilling, punching and cutting and other conventional machining. PCB material has advantages compared to other materials unparalleled. SMT surface mount power module for public art. No radiator, far smaller cooling effect excellent, good insulation properties and mechanical properties.
