Cleaning compositions. |
摘要 |
<p>This invention relates to a composition for cleaning contaminated electronic substrates. The compossition comprises a blend of 2-30% w/w of ethoxyethoxy ethanol and at least one other glycol ether derivative selected from butoxyethoxy ethanol, methoxypropoxy propanol, ethoxypropoxy propanol and C1-C5 monocarboxylic acid esters thereof. These esters are more environmentally safe and more user friendly than halohydrocarbons used hitherto for cleaning fluxes and solders from circuit boards.</p> |
