In the morning session, the PCB industry chain continued its strong performance, with fiberglass and copper foil sectors leading the gains. Shandong Fiberglass hit the daily limit twice in three days, while Tongling Nonferrous Copper Foil and Honghe Technology rose over 6%, hitting new all-time highs. Dongcai Technology, Defu Technology, and Changhai Co. were among the top gainers. On the news front, on April 28, Kingboard Laminates, a leading CCL manufacturer, issued an official price hike notice, citing elevated copper prices and tight fiberglass cloth supply, which led to a sharp rise in CCL costs. Effective immediately, the company raised prices of FR-4 CCL and PP prepreg by 10%.
