What is a solder wick? Discover how to choose the best solder wick, its practical applications, and high-quality product lines from Hapoin.
What is a solder wick?
Solder wick It is a fine, braided copper wire coated with flux (rosin), used to draw molten solder away from solder joints during electronic repair or manufacturing.
When the solder wire is placed on the joint and heated with a soldering iron, the solder melts and is drawn into the joint by capillary action, quickly and effectively cleaning the weld.
This is an indispensable tool in:
- PCB repair
- Removing multi-pin IC components
- Rework in SMT
- Precision electronics manufacturing
Structure and operating principle
Solder wicks are typically made from:
- Fine braided copper wire
- Flux coating aids heat transfer.
When heating the molten solder, capillary action draws it into the wire, effectively cleaning the solder joint without damaging the PCB.
Thanks to this design, the solder wick can quickly absorb solder, minimize damage to components, and improve repair accuracy.
Common types of solder wick
Currently, solder wick on the market is primarily classified by size and application:
According to size
- 1.5mm: small components, IC
- 2.0mm – 2.5mm: most common
- 3.0mm – 3.5mm: large weld
Popular lines such as:
- 2.0 mm (CP-2015)
- 2.5mm (CP-2515)
- 3.0mm (CP-3015)
- 3.5mm (CP-3515)
According to material & technology
- Standard copper wire
- Wire with premium flux (solders faster)
- Halogen-free cable (environmentally safe)
Which type of solder wick is best?
There is no single “absolute best” type; the choice depends on your specific application needs. However, here are some important criteria for selecting high-quality solder wick:
✔ Tin-soldering capability
The wire must have a well-braided structure to pick up solder quickly and cleanly.
✔ Softness and heat transfer
The flexible wire ensures good contact with the solder joint, enhancing suction efficiency.
✔ High-quality flux
Flux enhances thermal conductivity and cleans the solder joint.
✔ Safety and standards
Halogen-free products are more environmentally friendly and safer to use.
Some popular solder wick options
Characteristics:
- Made from braided copper
- Common length: 1.5 m
- Various sizes from 2.0 mm to 3.5 mm
Suitable:

Mistakes When Using Solder Wick
- Incorrect size selection → ineffective suction
- Insufficient heat → solder does not melt
- Reuse the tin-saturated wire.
- Failure to clean the soldering iron tip
-> This is the reason why the repair process is inefficient and productivity declines.
Benefits of Choosing the Right Solder Sucker
- Quickly clean the solder joint
- PCB and component protection
- Increase repair accuracy
- Optimize work performance
Conclusion
Solder wick is an essential tool in the electronics industry. , helping to ensure weld quality and repair efficiency. Selecting the right type of wire for the specific application will increase productivity, reduce defects, and enhance process stability in manufacturing.
