Recent news headlines have suggested that the U.S. Federal Communications Commission (FCC) has “banned all testing laboratories in China and Hong Kong.” Understandably, this has created concerns around PCB testing, material approvals, UL listings, and the continued use of established test laboratories in Asia. The good news is that for most PCB, PCB material, and PCBA testing, nothing has changed. Let’s separate fact from fear.

Underfill is a polymeric material used to fill the gap between a printed circuit board and the underside of surface-mount area-array packages such as BGA, QFP, and QFN devices, thereby surrounding and protecting the solder interconnections. This material increases the component's reliability when subjected to mechanical impacts and shocks by distributing forces. 

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, environmental protection using potting, coatings, and encapsulation is now a core design priority.
