Residue Removal

The flux in CORE 230 is formulated for use in a no-clean assembly process. If cosmetics or the end use application requires removal of the post reflow residue, standard rosin-based residue removal techniques can be utilized. This includes, but is not limited to: spray in air, immersion spray, vapor degreasing, or ultrasonic type cleaning processes.

Storage

CORE 230 has a shelf life of 3 years when stored in a dr y, non-corrosive environment such as a low-humidity dry cabinet. Direct sunlight, excessive humidity and storage near heat sources should be avoided.
