What this manufacturer makes
Allfavor is the PCB manufacturing business of Jiangsu Benchuan Intelligent Circuit Technology. Its official company profile places the main operation in Nanjing’s Lishui Economic Development Zone and describes a high-mix, low-volume manufacturing model with short delivery cycles. The product portfolio includes high-frequency and high-speed circuits, metal-based boards, heavy-copper boards, flexible circuits, rigid-flex and HDI. Its high-frequency catalogue shows Rogers-based constructions and a 6.0 mm thick example. Catalogue examples identify available work types; they do not establish a universal process window for every material grade.
