Aluminum PCB Advanced Circuits
Specification
Aluminum Printed Circuit Boards Contain a Thin Layer of Thermally
Conductive Dielectric Material that Transfers Heat.
There are many names for
these products; Aluminum clad, aluminum base, Metal clad printed Circuit Board (MCPCB), Insulated Metal Substrate(IMS or IMPCB), Thermally conductive PCBs, etc… but they all mean the same thing
and perform the same way.
How Are
Aluminum PCBs Made?
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.
Operating theory:
The power device surface
mounting on circuit layer, it is ideally suited for the mounting of high power light emitting diodes (LEDs) easily dissipating the heat generated by power devices.
Aluminum based PCB used:
1. Audio devices: input,
output amplifiers, balanced amplifiers, audio amplifier, preamplifier, power .
2. Power Supply: Switching
Regulator,DC / AC converter,SW regulator.
3. Telecommunications
electronic equipment: high-frequency electric amplifiers ,Filtering appliance ,Transmitter circuit,etc.
4. Office automation
equipment: Electric motor,
5. Automotive: Electronic
regulator, Ignition, Power
6. Computer: CPU board
,Floppy drive ,Power
7. Power Modules:Converter,
solid-state relay ,Power Rectifier bridges,etc
8. Lamps Lighting: with the
promotion of energy-saving lamps, Aluminum base PCB , used on LED lights ,begin large-scale application.
Benefits of
Aluminum PCBs
Heat dissipation 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
Thermal transfer
exponentially more efficient than a conventional rigid PCB.
Lower copper weights than
suggested by the IPC heat-rise charts can be used.
MCPCB & Metal Core PCB & LED
PCB
MCPCB, Aluminium PCB, or
call LED PCB are the circuit boards which use a
base metal material as the heat spreader portion of the Aluminum clad Circuit
Board, Aluminum
PCB has good thermal conductivity, electrical insulation and mechanical processing properties, it's the most excellent and cheap cooling solutions.
MCPCB/Metal core PCB can be
advantageous to use for their ability to integrate a dielectric polymer layer with a high thermal conductivity for a lower thermal resistance. Metal core PCB transfer heat 8 to 9 times faster
than Rigid FR4 PCB. MCPCB laminates dissipate heat, keeping heat generating components cooler which results in increased performance and life. Metal core PCB are most widely found in LED
technologies, using a metal core PCB in these LED products and applications help to greatly reduce the heat emitted.
