Stannol Flux Pen mod. X32 10i 10ml
Stannol X32-10i No-Clean Flux Pen 10 ml, halide-free, with low resin and solids content. Alcohol-based liquid flux with a precision applicator tip, leaving no visible residues after soldering. Developed by pioneers of No-Clean technology.
Ideal for PCB repairs, SMD and fine-pitch soldering, production of photovoltaic modules, and consumer electronics. Compatible with both Pb-free and leaded solder. Maximum solder bath temperature: 260 °C. IPC classification: ORL0.
The Stannol X32-10i No-Clean Flux Pen 10 ml is a professional precision tool for electronic soldering, ideal for quick PCB repairs, soldering SMD and fine-pitch components, and for assembling photovoltaic modules. The alcohol-based liquid flux (2-propanol) is dispensed precisely onto the soldering point thanks to the applicator tip, ensuring optimal surface activation and clean soldering without visible residues.
What is a No-Clean flux and why use it?
A No-Clean flux is formulated to leave negligible residues after soldering, eliminating the need to clean the printed circuit board in the standard production cycle. Stannol’s X32-10i was developed by pioneers of No-Clean technology: it contains a very low amount of resins and solids, is halogen-free, and offers a wider process window compared to conventional No-Clean fluxes. Soldered boards can be coated with protective varnish (conformal coating) without the need for pre-cleaning.

Recommended Applications
The X32-10i is certified and recommended for:
- Production of photovoltaic solar modules — main application indicated by Stannol, thanks to the higher solvent content formulation which ensures optimal activation on the metal contacts of the cells
- Consumer electronics and telecommunications — fast soldering of through-hole and SMD components without bridging or capillary rise (wicking)
- PCB repairs — localized and precise application on the soldering point thanks to the tip
- Fine-pitch soldering — the low solids content reduces residues and keeps the surrounding area clean
- Applications with conformal coating — soldered boards can be coated directly without pre-cleaning
- Professional rework and repair — compatible with both Pb-free and standard Sn/Pb solders
The 10 ml pen format is ideal for manual use and workbench applications. For industrial wave or spray applications, Stannol also supplies the X32-10i flux in bulk format.
Compatible Substrates and Surfaces
The X32-10i is recommended for clean copper PCBs or tin-lead coated boards. It works correctly on almost all solder resists. It is recommended not to apply the solvent in prolonged contact with polystyrene, polyester, or polycarbonate.
Safety Warnings
The product contains 2-propanol (isopropanol). Classified as a highly flammable liquid and vapor and eye irritant according to Regulation EC 1272/2008 (CLP). Use only in well-ventilated areas, away from heat sources, sparks, and flames. Wear gloves and protective goggles. In case of eye contact, rinse thoroughly. Store in a cool, well-ventilated place and keep locked up. Dispose of according to local regulations.
Frequently Asked Questions
What does No-Clean mean for a flux?
A No-Clean flux is formulated to leave residues so minimal that cleaning the PCB after soldering in the standard cycle is not required. The residues of X32-10i are chemically inert and non-corrosive, so they do not compromise the long-term reliability of the circuit. This results in savings of time, costs, and solvents in the production process.
Is the X32-10i flux suitable for soldering photovoltaic modules?
Yes. Stannol indicates the production of solar modules as the main application for X32-10i, thanks to its higher solvent content compared to conventional No-Clean fluxes. This ensures optimal wetting of the metal contacts of photovoltaic cells and a wide process window that adapts to different machine configurations.
How do you use the X32-10i flux pen?
Shake gently before use. Apply the tip directly to the soldering point or the area to be treated on the PCB, pressing lightly to release the flux. Apply heat with the soldering iron or reflow station immediately after. Do not leave the cap open between uses to avoid solvent evaporation. Store vertically with the cap closed.
Is it compatible with Pb-free and leaded solders?
Yes. The X32-10i is compatible with all standard solder alloys, both lead-free (Pb-free, e.g., SAC305) and leaded (e.g., Sn63Pb37). The recommended maximum solder bath temperature is 260 °C, but in many applications, it can be lowered to 235 °C with optimal results.
Can I apply conformal coating without cleaning the PCB after soldering?
Yes. Thanks to the No-Clean formulation with very low resin content, boards soldered with X32-10i can be coated directly with protective varnish (conformal coating) without the need for pre-cleaning, simplifying the production process and reducing costs.
