Shielding against electromagnetic interference (EMI), both internal and external, is going to be a crucial step manufacturers must take for the foreseeable future. That means the EMI shielding market will almost certainly continue to grow.
EMI shielding is a crucial part of modern product design. As more sources of interference enter the market, manufacturers can expect increased demand for shielding against interference.
Predictions of growth from research organizations
Research into the market bears out projected increases in the market. For instance, in a February 2020 report, Credence Research projected that the global EMI shielding materials market would experience a compound annual growth rate of 6.2% between 2018 and 2026.
Meanwhile, MarketsandMarkets Research projected growth from $6.8 billion in 2020 to $9.2 billion by 2025. They put the CAGR at 6.3% for that time period.
Potential reasons for growth in EMI shielding markets
What’s driving that growth? First of all, there are ever-more sources of EMI and radiofrequency interference in the world. These include:
- Increasing prevalence of devices connected to WiFi and cellular networks
- New 5G networks and cell phone towers
- Vehicles with electronic components, including “smart” and self-driving vehicles, as well as military and aerospace vehicles
That’s in addition to ever-present sources of EMI, including natural sources such as lightning and solar storms; unintentional radiation from power lines and consumer electronics; and intentional radiation from TV, radio, and wireless technology.
Demand for more sophisticated EMI shielding technology
As EMI shielding is integrated into more and more types of products, manufacturers and designers are also looking for solutions that offer effective shielding without adding too much unnecessary weight. Additionally, shielding will often need to withstand harsh conditions and temperature fluctuations, avoid interfering with capabilities such as touchscreens, and be cost-effective within the final product.
Shielding products that fit these specifications will continue to be a source of growth within the industry as well.
