DI Water vs. Chemistry
It is noteworthy that while most cleaning processes in the North American market rely on cleaning with deionized (DI) water only (for OA flux removal), recent market studies suggest that water is beginning to reach its cleaning limitation, favoring the use of aqueous processes. It might sound academic but even the term “aqueous” oftentimes is misunderstood or misinterpreted.
Aqueous is a term that implies the use of aqueous-based chemistry; for example, an application concentration of 15% mixed with DI water. The level of active concentration actually is secondary; however, aqueous implies the addition of active ingredients.
