What this manufacturer makes
Difeida Electronics manufactures printed circuit boards in Jiangsu. Its official company information describes single-sided, double-sided, multilayer and aluminum-base products. The catalogue includes a twelve-layer board with press-fit connections, as well as embedded-copper constructions for thermal management. These are separate product examples. For the twelve-layer construction, the press-fit connector, plated-hole dimensions and insertion-force requirements need to be agreed from the engineering drawing; they cannot be inferred from the appearance of the board.
