Insulated Metal Substrate (IMS) / Aluminium printed circuit boards
Aluminium backed PCBs have many benefits over conventional PCBs:
• Dissipation of heat without using additional heatsinks.
• Mechanically rigid, increasing the physical strength of the assembly
• Reduces the effect of thermal stress on all components, increasing life
and durability.
• Improved thermal conduction leading to versatility in component and
tracking layout enabling PCB dimensions to be reduced.
• Reduces component operating temperatures, improving reliability.
• Substrate aluminium can be drilled / machined and routed, aiding PCB
mounting.
Cephos can assist in the design of your aluminium
PCB, maximising the benefits that an aluminium pcb can exhibit over
conventional pcb material, reducing costs in the areas of pcb dimensions, reduction in the
requirement of bulky heatsinks
and pcb mounting hardware
The aluminium pcb is ideally suited for the mounting of high power light emitting diodes (LEDs) easily dissipating the
heat
generated by 1W, 3W etc power devices.
COBRITHERM® is an Insulated Metal Substrate (IMS), a base of thick aluminium clad with ED copper foil
COBRITHERM® is designed for
effective thermal dissipation. With a proprietary formulated epoxy-ceramic
bonding layer,
high thermal conductivity, dielectric strength and thermal
endurance is guaranteed. Mainly intended for SMD technologies,
the laminate can
resist all kinds of mass soldering processes at high
temperatures. The laminate is supplied with a
PETP protective film on the
aluminium side to protect it against wet PCB processes.
Available material dimensions:
Copper: 35, 70, 105 and 210 micron
Aluminium: 1, 1.5, 2, 3 mm
