Soldering flux paste CYNEL TOP-44E816 27 g for electronics and PCB work

CYNEL TOP-44E816 soldering flux paste (27 g) is formulated for electronics assembly and printed circuit board (PCB) soldering. Supplied as a compact paste, it promotes reliable wetting and controlled solder flow during manual soldering and rework operations. The composition is intended to aid removal of surface oxidation and to support formation of consistent solder joints on small components and PCB pads, making it suitable for precision repair and assembly work.

Advantages

The paste form provides accurate placement and reduced spreading compared with liquid fluxes, allowing targeted application to specific pads or component leads. It improves solderability by aiding oxide removal and enhancing solder flow, which contributes to more uniform joints and fewer cold solder defects. The compact packaging and moderate viscosity are designed to minimize waste and facilitate use in manual and touch-up soldering tasks.

Suitable for

• Manual soldering of through-hole and surface-mount components
• PCB rework, repair and touch-up soldering
• Precision electronics assembly and component replacement

Key specifications

• Form: compact paste suitable for pinpoint application
• Net weight: 27 g
• Intended use: electronics and PCB soldering, rework and repair
• Compatibility: designed for common solder alloys used in electronics
• Viscosity: medium, balanced for manual dispensing and controlled spread

How to use

Apply a small amount of flux paste to the target pad, lead or joint area before heating. For surface-mount work, use a fine tool or needle to deposit paste precisely on pads or component leads. Heat the joint with a soldering iron or rework station until solder flows and forms a smooth fillet; observe proper temperature and dwell time appropriate to the component and PCB. After soldering, clean residues according to the flux cleaning requirements for the specific assembly—if the flux is classified as non-clean, remove residues with an appropriate solvent or cleaner to prevent long-term corrosion or electrical leakage.

Usage recommendations

Use in a well-ventilated area and follow standard ESD and safety procedures for electronics work. Select soldering temperatures suitable for the component materials and board construction, and limit heat exposure to prevent thermal damage. Store the paste in a cool, dry place and reseal the container after use to maintain consistency and shelf life.
