Abstract
A magnetic element (100) includes a board unit (2) including a paddle board (21) having a row of first conductive vias (251) and a row of second conductive vias (252) for insertion of terminals (3), a number of embedded magnetic components (22), and a number of SMDs (surface mount devices) (23) mounted on the paddle board by SMT (surface mount technology). Each embedded magnetic component includes a magnetic core (221) embedded in the paddle board, and a number of PCB (printed circuit board) layout traces (222) disposed in the paddle board. Each PCB layout trace includes a first PCB layout trace (222a) encircling around the magnetic core and connecting with the first conductive via, and a second PCB layout trace (222b) encircling around the magnetic core and connecting with the SMD.
