Clearflow 7000: Frequently Asked Questions
Is DKL Clearflow 7000 compatible with SN100C?
+
Yes, this VOC-free water-based flux is specifically engineered for high-performance lead-free alloys like SN100C® and SAC305. It provides excellent wetting and hole-fill in both wave and selective soldering environments.
Does Clearflow 7000 require board washing?
+
As an ORL0 classified flux, it is designed for “no-clean” applications where residues are minimal and non-corrosive. However, because it is water-based, any remaining residue is fully water-soluble and can be easily removed with warm water if your process requires it.
What is the recommended pre-heat temperature?
+
For optimal results with VOC-free flux, we recommend a top-side pre-heat temperature of 100-135°C. This ensures all water is evaporated before the PCB contacts the solder wave, preventing spitting or solder balls.
