Carbon-conductive ink SD 2843 HAL Technical Report
●The carbon-conductive ink SD 2843 HAL is a 1-pack screen printing ink that, on account of selected special carbons and high-quality types of graphite, displays an excellent conductivity even after soldering. The achieved conductivities are to a large extent dependent upon the selected curing conditions (see Item "Resistance in relation to curing conditions”).
●The carbon-conductive ink SD 2843 HAL is suitable for touch-key contacts and enables the substitution of gold on contacts, the production of cross-over conductors (cross-over technology) as well as the creation of printed resistances. Further applications include migration protection for silver-conductive ink, electro-mechanical keyboards, foil keyboards for computers, switch contacts, low-voltage circuits, shield areas and heating elements.
●Since the performance of the carbon-conductive ink SD 2843 HAL largely depends on the condition of the contact module we recommend to carry out extensive trials on the cycle resistance under conditions of use.
