951 No-Clean Soldering Flux Pen

The 951 No-Clean Soldering Flux Pen is an essential precision tool designed for clean, reliable electronics assembly and rework. Specially formulated for delicate Printed Circuit Boards (PCB) and Flexible Printed Circuits (FPC), this flux pen applies a controlled layer of halogen-free, non-corrosive rosin flux directly where you need it—eliminating excess mess and improving solder wetting.

The "no-clean" formula leaves virtually no conductive or sticky residue behind, eliminating the need for post-solder washing with isopropyl alcohol. It is the ideal companion for fine-pitch surface-mount (SMD) soldering, touch-ups, and surface re-balling.

Key Features

• Precision Chisel/Felt Tip: Spring-loaded felt nib allows controlled, targeted application without overspray or dripping on sensitive components.

• No-Clean Formula: Low solids content leaves minimal, non-conductive residue that does not require cleaning after soldering.

• Halogen-Free & Non-Corrosive: Safe for multi-layer PCBs, delicate flex circuits, and delicate copper traces—prevents long-term board corrosion.

• Improves Solder Flow & Wetting: Quickly breaks down surface oxides to promote smooth solder flow, shiny joints, and prevent bridging between tight pins.

• Reflow & Hand Soldering Ready: Ideal for use with soldering irons, hot air rework stations, and reflow ovens.

• Protective Screw Cap: Keeps the felt tip moist and prevents evaporation when not in use.

Typical Applications

• Surface Mount Device (SMD/SMT) Rework: Soldering fine-pitch IC chips, QFP, SOP, and 0603/0805 passives.

• Flex Cable & FPC Repair: Applying flux to delicate ribbon cables, display connectors, and mobile phone board traces.

• Through-Hole Touch-Ups: Removing bridges and improving solder fill on header pins and wire terminations.

• Solar Panel Busbar Wire Jointing: Applying flux to tab wire before soldering solar cells.
