INSULATED METAL SUBSTRATES MARKET OVERVIEW

The global insulated metal substrates market size is predicted to reach USD 3.32 billion by 2034 from USD 1.25 billion in 2025, registering a CAGR of 11.48% during the forecast period from 2025 to 2034.

The United States Insulated Metal Substrates market size is projected at USD 0.41 billion in 2025, the Europe Insulated Metal Substrates market size is projected at USD 0.30 billion in 2025, and the China Insulated Metal Substrates market size is projected at USD 0.38 billion in 2025.

Insulated metal substrate consists of a metal baseplate covered by a thin layer of dielectric and a layer of copper The FR-4-based dielectric is usually thin because it has poor thermal conductivity compared to the ceramics used in DBC substrates.  IMS is made with a metallic support plate or a metallic material. The material or plate is combined or added as the thick base or inner layer of the circuit board. The key purpose for the incorporation is for the material to augment both the thermal and mechanical properties of the circuit board. Aluminum is the utmost common metal used though you can also have them manufactured with a stainless steel or copper base for extremely high power compactness plans.  It is commonly used in LED lighting, automotive electronics, motor drives, and radio frequency amplifiers among other applications. Massive demand for electronic goods there has been an upsurge in the percentage of various products that are incorporated into those goods which has led to an increase in the capacity of those goods to disperse heat.

Insulated metal substrates is especially beneficial in high-power and high-frequency applications where efficient heat intemperance is essential to maintain the performance and reliability of electronic devices. Insulated metal substrates are utilised for the purposes of engrossing heat from a variety of components and transferring that heat. A rise in the use of insulated metal substrates in LED lighting uses may be responsible for the segmental boom that is foreseen to occur during the upcoming time period. The segmental boom will be driven by a rise in the operation of aluminum-based insulated metal substrates in LED lighting uses for the purpose of boosting the performance of the product. Participating are fixing their efforts on encouraging R&D.

KEY FINDINGS

COVID-19 IMPACT

Pandemic hampered the market due to unexpected disruption in the sector

The global COVID-19 pandemic has been unprecedented and staggering, with insulated metal substrates market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden rise in CAGR is attributable to the market growth and demand returning to pre-pandemic levels once the pandemic is over.

Covid 19 pandemic has extremely affected the whole world. It caused many unexpected disruption and affected the industry. Covid 19 had negative impact on the market due to economic slowdown, unpredictability in financial sector and high unstable market. The pandemic resulted in decreased demand due to a disrupted supply chain, drop in sales of products, delivery schedules. Travel bans imposed affected business collaboration and partnership. Demand had recently reduced due to travel bans and lockdown during the COVID-19 pandemic. The continuous loss in the business due to the lockdown measures is projected to directly influence the growth of the investments in the market.
