Dry Film Waste Treatment: A Reliable and Cost-Effective Alternative to a Persistent Problem
Typically, companies involved in both
printed circuit board manufacturing
as well as Photo Chemical
Machining will utilize Dry-Film
Imaging technology for the development
of various images onto
metal substrates. rmmediately following
this imaging process is a chemical developing
process. Additionally, there is a
subsequent stripping process after electroplating.
As a by-product of these
operations, the manufacturer is left with
spent developer and stripper solutions,
which are generally resist-laden, metal
bearing and alkaline in nature.
