structure
construction of board
PCB aluminum clad circuit board material is a metal, a copper foil, and a thermal insulation layer consisting of a metal substrate, its structure is divided into three layers:
circuit layer: CCL corresponds to the line of 1oz copper foil thickness general PCB to 10oz.
insulating layer: insulating layer is a layer of thermal insulation materials with low thermal resistance. Thickness: 0.003 "to 0.006" inches is the core technology of aluminum clad lies, has received UL certification.
group layer: the substrate is a metal, typically aluminum or copper may be selected. And conventional aluminum clad epoxy glass cloth laminate board
PCB aluminum plate from the circuit layer, thermal insulation layer and a base layer composed of a metal; circuit layer (i.e., copper) printed circuit is typically formed after etching, so that the respective component parts connected to each other, under normal circumstances, the circuit layer requires a large current carrying capacity, so that use a thicker copper foil thickness is generally 35μm ~ 280μm;
is a thermally insulating layer PCB core technology where the aluminum plate, it is generally filled with a specific polymer composed of special ceramic, low thermal resistance, good viscoelastic properties, heat aging has the ability to withstand mechanical and thermal stress. Thermal insulation layer IMS-H01, IMS-H02, and other high-performance LED-0601 aluminum plate PCB is the use of such technology, it has very good electrical insulation properties and thermal conductivity high strength;
< p> metal substrate is an aluminum substrate supporting member required to have high thermal conductivity, typically aluminum, may be used a copper plate (copper plate which can provide better thermal conductivity), suitable for drilling, punching, and cutting machining and other conventional . PCB material as compared with the incomparable advantages over other materials. Suitable surface-mount power components SMT public art. No radiator, greatly reduced, an excellent cooling effect, good insulation properties and mechanical properties.use
