  • halogenated hydrocarbons in particular chlorinated hydrocarbons and fluorochlorinated hydrocarbons (hereinafter referred to as CHCs and CFCs) are used.
  • the halogenated hydrocarbons have a number of advantages due to their excellent cleaning action for certain applications. They dissolve practically all fats and waxes, even flux and rosin can be removed at normal temperature. In most cases, heating the substrate to be cleaned is just as unnecessary as a subsequent rinsing process with pure water. The cleaning process itself runs in very short periods of time. Due to the rapid evaporation of the halogenated hydrocarbons, the cleaned parts dry immediately with practically no external energy supply.
  • halogenated hydrocarbons are the only, but all decisive, disadvantage of extreme environmental hazards.
  • they have a high ozone depletion potential, which means that their use due to legal measures to protect the ozone layer will be severely restricted in the next few years and will already be prohibited in some countries, on the other hand, CFCs and especially CHCs have a high water hazard potential.
  • the parts to be cleaned are exposed to low-pressure plasma.
  • the plasma itself is created by the action of microwave radiation on a certain process gas.
  • oxygen, hydrogen and argon are used depending on the material of the parts to be cleaned.
  • the plasma reacts at relatively low temperatures in the range of 50 to 100 ° C with the fat or oil of the contaminated parts and brings these substances into the gas phase.

  • Terpen-based cleaning agents have also been proposed as a replacement for the HKW. Due to their structure, which is close to that of aromatic hydrocarbons, natural terpenes are good solvents for fats, oils and resins and especially for those known as rosin summarized terpene resins. Rosin usually forms the basis of the soldering flux used in the electronics industry. However, the terpenes have the disadvantage of evaporating only very slowly from the cleaned workpieces due to their high boiling point. On the other hand, there is a difficulty in separating the high-boiling terpenes from the solutes by distillation. For this reason, the terpenes often have to be rinsed off with a different medium from the cleaned workpieces. Although water is suitable as a rinsing medium, the addition of an emulsifier and a

  • Solvents are used, an increased outlay on equipment, since precautions for explosion protection must be taken.
  • many terpene-based cleaners due to their skin-toxic properties, cause skin diseases such as skin scabies in workers, and such cleaners are therefore prohibited in the United States, for example.
  • cleaning agents containing isopropyl as a substitute for HKW has also been proposed.
  • these cleaning agents have the disadvantage that isopropanol has only a limited ability to dissolve greasy or wax-like impurities, and on the other hand the use of isopropyl alcohol due to its low flash point means that the cleaning systems are equipped with special agents to ensure fire safety.
