en.Wedoany.com Reported - China's Yihao New Materials recently issued an announcement regarding abnormal fluctuations in stock trading, disclosing the progress of its HVLP (Very Low Profile) copper foil, which has drawn market attention. HVLP copper foil is primarily used in high-frequency and high-speed circuit copper-clad laminates and corresponding multilayer boards. In the announcement, the company stated that its mass production progress for HVLP copper foil is slower than some industry peers, and it is currently in the sample testing, analysis, and certification stage. There is significant uncertainty regarding whether it will pass customer certification and ultimately achieve mass production.

Regarding the progress of the fundraising investment projects that investors are concerned about, Yihao New Materials also disclosed that the second phase of the "Annual Production of 10,000 Tons of High-Precision Electrolytic Copper Foil Project"—the workshop for producing 5,500 tons of high-precision electrolytic copper foil per year—has been completed. Currently, the company is advancing the installation and commissioning of major production equipment. Due to factors such as equipment delivery timelines, repeated calibration of installation precision, and multiple rounds of optimization of process parameters, the specific production start date for this project still faces certain uncertainties.
