The present application relates to the field of
electronic equipment maintenance, in particular to a
cleaning agent for precise
electronic equipment with precise control of
evaporation rate and a preparation method thereof, which is a high adaptability
cleaning agent with controllable
evaporation rate for cleaning precise
electronic equipment. The
cleaning agent is prepared by mixing two components in a certain proportion, which can accurately adjust the proportion of the two components according to the temperature of the construction environment and the
pollution situation of the equipment on site. It can not only effectively remove various polar and non-polar pollutants on the surface of the circuit board, but also realize precise control of the
evaporation rate, so as to complete the effective removal of all pollutants in the optimal "contact-
dissolution-peeling-evaporation" kinetic window, thereby ensuring the safe and stable operation of the electronic equipment.
