Compaq Plans to Eliminate Use of Chlorofluorocarbons
HOUSTON (AP) _ Compaq Computer Corp. plans to use a new manufacturing process to eliminate the emission of ozone-destroying chemicals from its factories.
The Houston-based personal computer manufacturer said Wednesday it will begin using a new, non-corrosive flux material to bond components to computer circuit boards.
That will eliminate Compaq’s need to use a chlorofluorocarbon cleaner applied to circuit boards to remove residue. The old flux would corrode circuit boards if not removed with the cleaner. The new bonding agent doesn’t corrode circuit boards, so it doesn’t need to be removed.
Chlorofluorocarbons, most commonly used as coolants in refrigerators and air conditioners, are among substances that deplete the ozone. The ozone layer in the Earth’s atmosphere blocks out many of the harmful ultraviolet rays that can cause skin cancer.
Last year, Compaq used more than 153,000 pounds of the chlorofluorocarbon cleaner, down from 270,000 pounds in 1989, said Debra Globe, company spokeswoman.
Under international agreement, chlorofluorocarbons are to be phased out of production in developed countries by century’s end and globally by the year 2010. Compaq plans to phase out use of all chloroflurocarbon by 1995.
