The present invention discloses an implementation method for stacked connection between isolated circuit components, whose setting is according to at least two circuit components connecting in parallel/series in a circuit, wherein, in accordance with a circuit connection configuration, a plurality of corresponding pins of the components are soldered directly, making the components form an integrated module in accordance with a desired connection configuration of the circuit, and saving circuit boards and wires. Comparing to the circuit limited in a PCB in the prior art, it is possible to construct a circuit unit by welding connection in a way of building-block approach, achieving a circuit in a 3D space through directly welding between components, and owning a wider design space, it may shorten the time used for a circuit from design to process.
