Problems solved by technology

However, due to the small size of such devices, after soldering to the circuit, the solder can easily flow to the side of the electronic component, causing a short circuit between the positive and negative terminals
This is more likely to happen with electronic components of small dimensions, only a few millimeters wide

Abstract

A double-sided surface mount electronic component comprises a core that is provided with a first electrode and a second electrode, respectively, on two opposite surfaces; and further includes a first insulating protective ring being arranged on the surface of the first electrode of the core and surrounding the first electrode to form a depressed portion. At least one end face of both end faces of the first insulating protective ring is raised to the electrode surface higher than the core to form the depressed portion. The depressed portion is provided with a conductive filler to ensure that the electrode of the core can be electrically connected to the outside.

Description

technical field [0001] The present invention relates to the technical field of semiconductors, in particular to a double-surface chip electronic component and a packaging method thereof (DMT: Dual-surface Mounting Technology). Background technique [0002] Electronic components with two electrodes, such as diodes, capacitors, resistors, and inductors, are widely used in various electronic circuits. It is a common electrode arrangement method to arrange positive and negative electrodes on two opposite surfaces. However, due to the small size of such devices, after soldering to the circuit, the solder can easily flow to the side of the electronic component, causing a short circuit between the positive and negative terminals. This is more likely to happen with electronic components of small dimensions, only a few millimeters wide. Therefore, how to avoid side flow of solder for small-sized electronic components is a problem to be solved urgently in the prior art. Contents o...
