أ circuit board thinner than paper is now a critical battlefield in global tech competition. From AI servers to smart vehicles, its performance directly determines the success or failure of electronic products.
At UGPCB’s testing lab, engineers place a newly produced AI server ثنائي الفينيل متعدد الكلور into a -55°C extreme cold environment, then rapidly transfer it to a 125°C high-temperature chamber after 30 ثواني. This harsh cycle test repeats 1,000 times – ensuring every micron-level circuit maintains signal stability under extreme conditions.
“Our project nearly missed its deadline due to PCB signal interference!” lamented a tech company R&D director. With the AI computing boom and smart vehicle electronic architecture revolution, high-end PCB manufacturing is undergoing unprecedented technological transformation and capacity competition.
