  • examples of the aqueous cleaners include glycol ethers, silicates and phosphates.
  • Another class of cleaning agent that is being used increasingly in the electronics industry is the terpene group, including such compounds as pinene, gamma terpinene, limonene, and dipentene. These compounds have the ability to dissolve or complex with rosin solder fluxes, oils, waxes, and greasy substances, and are characterized by relatively low toxicity and environmental biodegradability.
