Single Sided Aluminum 94v0 PCB Circuit Board Good Heat Dissipation
A thin layer of thermally conductive but electrically insulating
dielectric is laminated between a metal base and a copper foil. The
copper foil is etched into the desired circuit pattern and the
metal base draws heat away from this circuit through the thin
dielectric.
Aluminum PCB is a unique metal-based copper clad laminate; it has
good thermal conductivity, electrical insulation and machining
performance.
Aluminum PCB is one of metal-based pcb, including copper foil,
thermal insulating layer and metal substrate, its structure divide
into three layers:
- Circuit layer: the equivalent of an ordinary PCB, copper thickness
from 1oz to 10oz.
- Insulation layer: Insulation is a layer of thermal insulating
material with low thermal resistance. Thickness: 0.003 "to 0.006"
inch is the aluminum pcb core technology.
- Based Layer: a metal substrate, usually aluminum or copper may be
chosen.
The heat dissipation afforded by this construction is dramatically
superior to standard FR-4 constructions. The dielectrics used are
typically 5 to 10 times as thermally conductive as conventional
epoxy-glass and a tenth of the thickness resulting in thermal
transfer exponentially more efficient than a conventional rigid
PCB.
Although Power Converters and LEDs are the largest users of these
products, Automotive and RF companies are also looking to take
advantage of the benefits of these constructions. A single layer
construction is the simplest, most thermally conductive and most
cost effective construction. Designs with higher component counts
may not have room for all the required routing on a single layer.
In this case a two layer design is required. A thin sheet of
dielectric, typically around .006” thick, is drilled, plated and
etched much like a standard double sided printed circuit board. The
sheet is then laminated using thermally conductive bonding material
to the metal base. This extra routing layer results in components
farther away from the heat-sink and reduced heat transfer so this
construction is recommended only when necessary.
