Bonkote BON-102 Flux Pen | Refillable Rosin Solder Applicator
Bonkote BON-102 Flux Pen | Refillable Rosin Solder Applicator
The Bonkote BON-102 Flux Pen is a professional-grade, refillable rosin flux applicator designed for precise, clean PCB soldering. Whether you're working on BGA rework, surface-mount components, or through-hole connections, this compact pen gives you total control over flux application — protecting delicate copper traces and IC pins every step of the way.
Key Features
- Soft Brush Tip: The gentle brush nib applies flux smoothly without scratching PCB copper foil or bending IC pins, making it ideal for fine-pitch work.
- Refillable Design: The pen core reservoir holds liquid flux securely with no leaking or evaporation. Simply refill when empty — only the nib needs occasional replacement, saving money over time.
- No-Clean Formula Compatible: Works with no-clean rosin fluxes, minimising post-solder cleanup and keeping your boards residue-free.
- Controlled Flow Rate: The moderate liquid flow ensures consistent, precise application — no flooding or dry spots.
- Transparent Body: See exactly how much flux remains at a glance. The clear barrel lets you monitor flux levels without guessing.
- Dual Use — Cleaning Mode: Fill with isopropyl alcohol to convert the pen into a handy PCB cleaning brush for removing flux residue after soldering.
- Compact & Portable: Slim pen format fits easily in a toolkit, toolbox, or shirt pocket — ideal for bench work and field repairs alike.

Frequently Asked Questions
Q: Can the Bonkote BON-102 flux pen be refilled with any type of flux?
A: Yes — the BON-102 is a refillable flux pen compatible with most standard liquid rosin and no-clean flux formulations. Simply uncap the reservoir, add your preferred flux, and reseal. This makes it a very cost-effective tool for regular PCB soldering work.
Q: Does the BON-102 flux pen leave residue on the PCB after soldering?
A: When used with a no-clean flux, the BON-102 leaves minimal residue that does not require cleaning for most applications. If you prefer a fully clean board, simply refill the pen with isopropyl alcohol and brush over the soldered area to remove any remaining flux traces.
Q: Is the brush tip replaceable on the Bonkote BON-102?
A: Yes. The soft brush nib is designed to be replaceable, so you can extend the life of the pen body indefinitely. Replacing only the tip rather than the entire pen keeps running costs low and reduces waste.
