Simply uncap the reservoir, add your preferred flux, and reseal. This makes it a very cost-effective tool for regular PCB soldering work.\u003c\/p\u003e\n\u003ch4\u003eQ: Does the BON-102 flux pen leave residue on the PCB after soldering?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: Is the brush tip replaceable on the Bonkote BON-102?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Can the Bonkote BON-102 flux pen be refilled with any type of flux?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes — the BON-102 is a refillable flux pen compatible with most standard liquid rosin and no-clean flux formulations.
