The Government Circuit: Fewer Hammers, More Scalpels—What Divided Government Means for U.S. Trade Policy
SMT Perspectives & Prospects: What I Hope the Next Generation Will Carry Forward
Learning With Leo: Observations from IPC Builds in Paris
For decades, trucking was defined by horsepower, payload, and driver endurance. Today, the competitive edge lies in electronics, as advanced sensing, communications, and data processing systems reshape how commercial vehicles operate. The industry is rapidly digitizing, with electronic systems now critical to safety, uptime, and fleet efficiency. Technologies like ADAS, radar, lidar, and telematics enable real-time decision-making, while distributed sensors monitor key vehicle functions. Because these systems operate in harsh conditions—vibration, temperature swings, moisture, and chemicals—environmental protection using potting, coatings, and encapsulation is now a core design priority.
Telematics platforms serve as the fleet’s data backbone, transmitting information via Bluetooth, cellular, GPS, and V2X. Often placed in exposed locations, these modules require durable protection that maintains mechanical integrity and RF performance.
To meet these demands, circuit protection materials such as epoxy, silicone, and polyurethane are engineered for specific trade-offs. Polyurethane is increasingly favored for wireless applications, offering strong environmental protection without degrading signal performance.
