PCB Assembly, PCB Design and Manufacture
by Cephos Electronic Circuits Ltd - CEM (UK)

Cephos has been involved in the design, manufacture and assembly of aluminium backed printed circuit boards for many years, from prototyping to high volume production runs.

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.

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. 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.

COBRITHERM® by Aismalibar

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
