The required adhesive, the adhesive curingtemperature and the curing time has to be agreed between customer and manufacturer.1.9.5 Use of cleaning solventsIt is recommended to use flux, which does not need cleaning solvents.Otherwise the insulation resistance can be influenced by the remainders of soldering flux and cleaning solvents,because it is difficult to remove them from the space between resistor and printed board.If flux is used for the removal of flux residues the following solvents may be used: alcohol, such as ethanol, methanol, propanol, isopropanol, butanol; water.Reaction time of the solvent shall not exceed 5 min.If using other cleaning solvents, consultation with the resistor manufacturer is necessary.1.9.6 Pulse load cap
