Problems solved by technology
[0004] Conductive adhesives will inevitably have some structural defects during the sizing process or during long-term use. It is of great significance to find a simple and economical rework method. The current rework method is basically to cut off the glue and then re-construct, but When applied to some narrow spaces, this heavy work method cannot be realized

Abstract
The invention discloses a self-repairing organic silicon conductive glue, which is composed of organically modified vinyl silicone oil and conductive fillers, etc. The conductive glue has excellent conductivity, especially the conductive glue has low temperature self- Repair performance, can repair its own structural defects and restore electrical conductivity at 50‑80 °C.
Description
technical field [0001] The invention relates to the field of silicone conductive glue, in particular to a silicone conductive glue with self-repairing function. Background technique [0002] Conductive adhesive is a kind of special adhesive product with certain bonding strength and conductivity after curing. Compared with the traditional way of welding and conducting electricity, the operating temperature is lower when using conductive adhesive, which is more than 100 ℃ lower than the welding temperature; and due to the conductive The glue contains a certain amount of organic resin components, which can exhibit a certain degree of elasticity, thereby reducing the internal stress generated during the bonding process. At present, conductive adhesives have been widely used in the bonding and packaging of electronic components or components such as display screens, integrated circuits, and capacitors. Classified from the system point of view, conductive adhesives are divided in...
