What this manufacturer makes
Junda Electronics manufactures printed circuit products in Shunde, Foshan. Its official production information identifies Huanglian and Fuan production bases, and the catalogue separates single-sided, double-sided and aluminum-base boards. The company describes continuing investment in process equipment and environmental facilities. This profile concentrates on the double-sided board family. A sourcing decision should still establish the plant assignment, laminate specification and electrical-test requirements for the particular order.
