What this manufacturer makes
Guangde Dongfeng Electronics manufactures printed circuit boards in the Guangde Economic Development Zone in Anhui. Established in 2014 according to its official profile, the company lists double-sided boards, multilayers, aluminum substrates, ceramic boards and high-frequency products. The Chinese product section advertises a 1–16-layer manufacturing service, while the English overview specifies panel size and line-and-space capability. These are separate process disclosures; ceramic and metal-base constructions need their own engineering confirmation.
