Chip Quik CQ4LF-0.5, Liquid Flux No-Clean in 15ml (0.5oz) Squeeze Bottle w/ Tip
Chip Quik CQ4LF-0.5 — No-Clean Liquid Flux, 15ml Squeeze Bottle with Tip
Chip Quik CQ4LF-0.5 (SKU: CQ4LF-0.5) is a no-clean, VOC-free liquid flux for hand soldering, rework, and touch-up with both leaded and lead-free alloys. Classified ORL0 per J-STD-004, it leaves a non-corrosive, non-conductive residue that does not require cleaning in most applications. Supplied in a 15ml (0.5oz) squeeze bottle with precision tip for controlled, targeted flux application. Excellent shelf life — over 24 months refrigerated or at room temperature.

Frequently Asked Questions
Does CQ4LF-0.5 residue need to be cleaned after soldering?
In most applications, no — CQ4LF-0.5 is classified ORL0 (no-clean, organic, rosin-free, low activity) per J-STD-004, meaning the residue is non-corrosive and non-conductive and does not require removal. If your process or customer specification requires a clean board, use an appropriate no-clean flux remover — standard IPA may not fully remove ORL0 residues.
Is CQ4LF-0.5 compatible with lead-free soldering?
Yes — CQ4LF-0.5 is formulated for both leaded and lead-free applications, making it a versatile single-flux solution for mixed-alloy rework environments where both SnPb and SAC alloys are used.
What is the shelf life and storage requirement?
CQ4LF-0.5 has a shelf life of over 24 months both refrigerated and at room temperature (3–25°C / 37–77°F). Freezing will not degrade the product. If stored cold, allow 4 hours for the flux to reach operating temperature (20–25°C) before use.
Is CQ4LF-0.5 VOC-free?
Yes — CQ4LF-0.5 is VOC-free, making it suitable for use in facilities with strict VOC emission controls and reducing operator exposure to solvent vapors during flux application and soldering.
What is the advantage of the squeeze bottle with tip format?
The 15ml squeeze bottle with precision tip allows controlled, targeted flux application directly to the joint, pad, or component lead — minimizing flux spread to adjacent areas and reducing the amount of flux applied per joint. This is particularly useful for rework, BGA work, and fine-pitch applications where excess flux can cause issues.
