Electronic circuit boards with aluminum substrates

PCB circuit boards with aluminum substrates for effective heat dissipation

Overheating in printed circuit boards is a challenge in many industrial applications. ARC srl offers solutions featuring IMS electronic boards, which represent an innovative and strategic solution for numerous industrial sectors.

Overcoming thermal challenges in power electronics with aluminum substrates

The main problem with printed circuits using silicon technology is overheating due to the Joule effect, which shortens the circuit's lifespan.

In certain applications, this is a major problem.

I.M.S. (Insulated Metal Substrate) technology is our solution to overheating. This technology combines an insulated metal substrate with a copper layer to ensure maximum heat dissipation and guarantee the long-term durability and reliability of the circuits.

I.M.S. stands for Insulated Metal Substrate. It proves particularly effective in all applications where currents reach hundreds of amperes and where high heat dissipation capacity combined with great mechanical strength is required.

This solution offers an insulated metal substrate consisting of a layer of copper (of varying thicknesses), an electrical insulator, and a metal base.

I.M.S. boards are used for: 

• optimize heat transfer from active components or LEDs to the heat sink
• reduce assembly time for operators working on power equipment, where otherwise there would be many components that need to be secured individually with screws, washers, and silicone grease.

The distinctive feature of this type of board is that it offers high quality at a very low cost for mass production.

Key benefits of insulated metal substrates (IMS) for high-current applications

IMS boards are strategically integrated across a diverse range of industrial sectors, providing a competitive edge in thermal efficiency and system reliability:

1. Lighting sector: we contribute to the control of lighting loads, especially in LED lighting.
2. Automotive sector: in the automotive industry, they are primarily used in electronic control units (ECUs), vehicle lighting systems, etc...
3. Industrial sector: they are used in power supplies, welding equipment irons, etc.
4. Solar sector: I.M.S. boards are used in inverters for photovoltaic systems.

ARC srl is committed to providing high-quality, customized solutions for the thermal requirements of industrial applications.
