Abstract

The invention relates to a method of preparing a universal detacher for electronic components, comprising a desoldering paste for removing any type of electronic component. The invention comprises the alloying of tin, lead and mercury, together with zinc chloride, potato starch, petrolatum, camphor, eucalyptus and a colouring agent, which produces a desoldering paste for electronic components. The inventive desoldering paste can be used to retrieve any piece of electronic circuitry in full and without causing any damage.
