Description
Professional Electronics Solder Flux – ROHS Solder Paste 183 °C No-Clean Rosin Medium Temperature Flux (30 g Tube)
Experience precision and reliability with ROHS Solder Paste 183, a high-quality, environment-friendly
electronics solder flux engineered for both professional PCB assembly and everyday electronic repair.
This medium-temperature, no-clean rosin flux offers exceptional bonding strength and smooth, consistent solder joints.
Moreover, its buttery consistency and neutral pH make it easy to apply while ensuring a clean, professional finish
for every type of soldering task.
Product Description
This premium electronics solder flux paste provides excellent adhesion and smooth spreadability,
resulting in strong, bright, and clean joints. It is ideally suited for precision electronics such as
mobile-phone PCB assembly, chip soldering, and motherboard repair.
Furthermore, it maintains excellent insulation and surface integrity even after extended use.
- Oxide Film Removal: The active rosin compounds react chemically to remove metal oxides,
thereby improving solder adhesion and enhancing electrical conductivity. - Oxidation Prevention: Once melted, the flux forms a protective isolation layer that shields
solder joints from air exposure, thus preventing re-oxidation and improving long-term reliability. - Reduced Surface Tension: By increasing solder fluidity, this flux ensures smoother wetting
behaviour and more uniform solder distribution across all contact points.
Important Warning
⚠️ Safety Notice: This electronics solder flux is not suitable for soldering points on integrated circuits (ICs)
or for use on high-voltage components. After soldering, the joints should be thoroughly
cleaned with ethyl alcohol to remove any remaining flux residue.
Doing so helps maintain safety and prevents long-term degradation of sensitive components.
