Background

The advantages brought by the passive devices being placed inside the circuit board are not only space saving on the surface of the circuit board. The circuit board surface solder joints will generate inductance. The embedded mode eliminates welding points, thus reducing the inductance introduced, and further reducing the impedance of the power supply system. Thus, the embedded resistors and capacitors save valuable board surface space, reduce board size and reduce weight and thickness. Also, reliability is improved due to the elimination of solder joints (which are the most prone to failure introduction on circuit boards). The embedding of passive devices will reduce the length of the wires and allow for a more compact device layout, thus improving electrical performance.
