Elektroniikkaliima

Elektroniikkaliima, known in English as electronic glue or conductive adhesive, refers to specialized adhesives designed for use in electronic applications. These materials often possess unique electrical and thermal properties in addition to their bonding capabilities. Unlike standard glues, some electronic adhesives are formulated to conduct electricity, allowing them to be used as a substitute for traditional solder in certain circuit assemblies. This conductivity is typically achieved by incorporating conductive fillers, such as silver, nickel, or carbon particles, into the adhesive matrix.

The primary function of electronic glue is to secure components, protect sensitive areas, and provide electrical or thermal pathways where needed. They are particularly useful for applications where heat from soldering might damage delicate components, or where a flexible conductive connection is required. Common applications include bonding surface-mount components, attaching heat sinks to processors, sealing connectors, and repairing printed circuit boards.

Electronic adhesives come in various formulations, including epoxies, silicones, and cyanoacrylates, each offering different curing mechanisms, flexibility, temperature resistance, and conductivity levels. The selection of an appropriate electronic glue depends on the specific requirements of the electronic device, such as the operating environment, electrical load, and mechanical stress. Proper surface preparation is crucial for ensuring a strong and reliable bond, as well as optimal electrical or thermal performance.
