What this manufacturer makes
Fujian Yongsheng Electronics manufactures printed circuit boards and provides SMT assembly from Wendu Industrial Park in Fuding, Fujian. Its official introduction dates the business to 2001 and describes production, development, sales and technical service within the company. The public catalogue contains individual board samples, including multilayer examples, rather than a single numerical fabrication envelope. Listed application sectors include communications, industrial control, metering, security and household appliances. Buyers should obtain the stack-up and acceptance criteria for the selected sample before treating it as an orderable specification.
