Ycs Halogen-Free Soldering Flux

Ycs Halogen-Free Soldering Flux

Ycs Halogen-Free Soldering Flux is

a brand of solder paste and flux manufactured by Yang Changshun (YCS), commonly used for mobile phone and electronic component repairs. It is a no-clean, lead-free formula that provides excellent wetting and low residue. 

Key features of

Ycs Halogen-Free Soldering Flux

• Halogen-free: Contains no halogenated compounds, which can release toxic and corrosive gases when burned. This makes it a safer and more environmentally friendly option.

• No-clean: Leaves behind a minimal amount of non-corrosive, transparent residue, eliminating the need for a post-soldering cleaning process.

• Lead-free compatibility: The flux is formulated to work with lead-free solders, which have higher melting points and are increasingly mandated by environmental regulations like RoHS.

• Self-cleaning: YCS fluxes are designed to remove oxidation from the metal surfaces during the soldering process, which is essential for a strong, reliable solder joint.

• Insulation resistance: Products like the

  TFHF9200 flux

  ensure a high surface insulation resistance, which is important for the long-term reliability of electronic circuits.

• Versatile application: YCS offers a range of products, including paste and liquid fluxes, that are suitable for various applications, from manual repairs to automated wave soldering. 

Common uses

• Mobile phone repair: Used for delicate tasks like soldering components on printed circuit boards (PCBs) in mobile phones.

• BGA and IC repair: The flux's ability to clean and prepare surfaces is critical for Ball Grid Array (BGA) and Integrated Circuit (IC) rework.

• PCB assembly: Can be used in wave soldering for mass assembly of circuit boards.

• General electronics repair: Suitable for a variety of electrical DIY projects. 

Benefits of halogen-free fluxes

The move toward halogen-free materials is driven by both environmental regulations and product reliability concerns. The advantages include: 

• Environmental safety: Halogenated flame retardants in standard electronic products can release toxic fumes when incinerated for disposal. Halogen-free alternatives prevent this.

• Reduced corrosion risk: The residue from traditional fluxes containing ionic halides can cause corrosion and damage to electronic components over time, especially in the presence of moisture. Halogen-free fluxes mitigate this risk.

• Regulatory compliance: Manufacturers must meet standards like IEC 61249-2-21, which sets strict limits on halogen content. Using halogen-free flux helps companies comply.

• Improved product reliability: Halogen-free fluxes, particularly no-clean formulations, are engineered to provide enhanced reliability with excellent electrochemical performance and resistance to dendritic growth.
