Photoresist stripper composition and method of use |
摘要 |
An improved process for removing crosslinked photoresist polymer from printed circuit boards which comprises contacting the printed circuit board with methylene chloride containing from about 5 to about 10 volume percent of a mixture of methanol and methyl formate. Each additive must be present at a minimum concentration of one volume percent. Stabilizers for the methylene chloride, such as epoxides, may be present at amounts no greater than about 0.5 volume percent.
