Can ultra-long pcbs deliver better thermal performance?
Ultra-long PCBs improve thermal performance by utilizing a continuous copper surface area of up to 3,000mm to eliminate the 15°C temperature spikes typically found at inter-board connectors. In 2025, thermal imaging tests confirmed that a single-piece 1,800mm substrate achieves a 22% more uniform heat distribution compared to segmented designs. By supporting 10oz heavy copper and …
