Use Level 3 solvents with caution Do not use chlorine-based halogenated cleaning solvents, adhesives or coating agents. When halogenated chlorine-based solvents are used in the cleaning process, free chlorine is liberated from the solvent. This chlorine causes corrosion and deterioration of the aluminum inside the capacitor. Dangers of “Free-Chlorine”: After the solvent dries, the chlorine remains on the capacitor seal, the chlorine slowly permeates into the capacitor element causing corrosion and damage that happens slowly. It may take some time before a failure is apparent. A representation of the chemical reaction is on the following page. Cornell Dubilier • 1605 E. Rodney French Blvd. • New Bedford, MA 02744 • Phone: (508)996-8564 • Fax: (508)996-3830 • www.cde.com Application Guide Aluminum SMT Capacitors Reaction of Free-chlorine and Aluminum Combined free chlorine and hydrogen become hydrochloric acid, but it has high dissociation and most of it becomes chlorine ions. These chlorine ions react with the aluminum. The order of the reactions is represented below. 1.) Hydration of oxide film 2Al(OH)3 AlO3 + 3H2O 2.) Reaction of hydrated oxide film and chlorine (Dissolution of film) AlCI3 + 3H2O Al(OH)3 + 3HCI 3.) Reaction of aluminum and hydrochloric acid (Dissolution of aluminum) Al + 3HCI AlCI3 + 3/2H2 4.) Precipitation of aluminum hydroxide Al(OH)3 + 3HCI AlCI3 + 3H2O The entire reaction can be summerized as the following: Al + Al2O3 + 3HCI3 + 3H2O 2Al(OH)3 + AlCI3 + H3/2 Therefore the compounds produced by the reactions are aluminum hydroxide and hydrochloric acid from reaction #4; the hydrochloric acid is not consumed and acts as a catalyst. Solvents that should not be used Composition Boiling Point (ºC) Common Name 1.1.1 -Trichloroethane Trichloroethylene Tetrachloroethylene 74.1 87.2 121.1 Chlorosen Trichlene Perchloroenthylene Additional Cleaning Notes: 1.) Solvents containing CFC’s destroy the ozone layer and should be avoided to protect the global environment. 2.) To avoid solvent residue between the capacitor’s seal and the PC board, make sure the assembly is dried thoroughly after cleaning.
