Filtration system to remove photoresist film particles |
| abstract |
A method for removing a liquid stripper composition from a slurry comprised of the liquid stripper composition and of photoresist film particles which were removed from a circuit board substrate by using the liquid stripper composition. The slurry flows over the inner surface of the porous wall of a drum under gravity to form a generally uniform layer on the inner surface of the drum. Liquid escapes from the slurry through the porous wall of the drum. |
