A recently filed patent (Publication Number: US20230319988A1) describes an electrically conductive adhesive that can be used in electronic circuits. The adhesive includes an electrically conductive filler, with the surface of the filler coated in a layer of silver. The adhesive contains a specific volume of the conductive filler and silver, ranging from 29.0% to 63.0% and 3.5% to 7.0% respectively.

The electrically conductive filler in the adhesive has a core that can be made of various materials, including metals that are less conductive than silver and ceramics. Examples of these materials include alumina, silica, copper, and aluminum. The adhesive is in an ink state, which means it can be easily applied to different surfaces.

The patent also mentions the use of this electrically conductive adhesive in electronic circuits. It can be used to join various components, such as semiconductor devices, thermoelectric elements, chip components, LED components, and other electric components, onto a resin substrate. The resin substrate must have an electrically conductive part, which can be made of aluminum or copper.

Furthermore, the patent describes different methods for applying the electrically conductive adhesive onto the resin substrate. These methods include dispensing, screen printing, and gravure printing.

In summary, the patent presents an electrically conductive adhesive with specific properties and composition. It can be used in electronic circuits to join various components onto a resin substrate. The adhesive has a specific volume of conductive filler and silver, and the filler can have a core made of different materials. The adhesive is in an ink state and can be applied using different methods.
