The ammonium chloride leakage current test solution is used to simulate and investigate leakage currents on electronic components. Its composition forms a conductive environment that simulates, in particular, the influence of moisture and contamination on printed circuit boards. The dissociation of ammonium chloride in water creates a slightly conductive solution. In the application, the test solution is applied to the surfaces to be tested, allowing potential leakage currents to be identified and analyzed. In this way, this solution makes a decisive contribution to the quality assurance of electronic components.
