Product Information
Full details
The Chip Quik CQ4LF is an essential tool for hobbyists and professional electronics technicians who require a precise, easy-to-apply flux for both leaded and lead-free soldering. This 10ml pen delivers a water-based, VOC-free, and rosin-free formula that ensures excellent wetting for rework and assembly tasks without leaving stubborn residues behind, though users should ensure the surface is dry before application to achieve the best results.

FAQs
Do I need to wash off the board after using this flux?
No, it is a no-clean formula, but it can be easily cleaned with water or isopropyl alcohol if desired.
Is this flux safe for lead-free soldering?
Yes, the CQ4LF is specifically engineered to handle the higher melting temperatures and flow characteristics of lead-free solder.
Can I store this in the refrigerator?
Yes, although it is stable at room temperature, refrigeration will not harm the product and can be used as a storage method if preferred.
Is the formula flammable?
No, the flux is water-based and non-flammable, making it a safer alternative to alcohol-based flux pens.
How long does the flux last?
The CQ4LF has a shelf life of 24 months from the date of manufacture when stored properly.
Can I use this for plumbing repairs?
No, this product is designed specifically for electronics assembly and repair; it is not suitable for plumbing applications.
Troubleshooting
Flux is not flowing from the tip
Gently depress the tip against a scrap board to release air and encourage fluid flow, or check if the tip is clogged with debris.
Residue remains on the board
While the flux is 'no-clean,' any visible residue can be easily wiped away using a lint-free cloth dampened with water or isopropyl alcohol.
Solder is not wetting the pad
Ensure the PCB surface is clean of oxidation; if heavy oxidation exists, light mechanical cleaning may be required before reapplying flux.
Pros and Cons
Pros
- Non-flammable water-based formula increases workspace safety
- Precision tip minimizes waste and prevents oversaturation
- Compatible with both leaded and lead-free solder
- VOC-free and rosin-free for a cleaner work environment
- Long 24-month shelf life regardless of storage temperature
Cons
- Not suitable for applications requiring heavy-duty acid-based flux
- Water-based formula requires thorough drying before powering sensitive electronics
- 10ml volume may be insufficient for high-volume industrial production lines
Setup, Compatibility & Care
To prepare the pen for use, remove the cap and gently press the felt tip against a hard surface to prime the flow. Store the pen in a cool, dry place; while the product is stable at room temperature for up to 24 months, keeping it capped tightly is essential to prevent the tip from drying out. If the tip becomes clogged or degraded over time, it can be cleaned or wiped down with a small amount of isopropyl alcohol (IPA). When finished, ensure the cap clicks securely into place to maintain the integrity of the remaining flux.
