Ycs No 1 Flux Welding oil

YCS No. 1 is a brand of no-clean soldering flux (often called "soldering oil" or "welding oil") primarily used for repairing electronics, such as mobile phones and printed circuit boards (PCBs). It is a halogen-free formula that helps to clean and protect the solder joint during the soldering process. 

Key features

• No-clean formula:

  YCS No. 1

  minimizes residue after soldering, which makes cleanup easier and reduces the risk of contamination on sensitive electronic components.

• Halogen-free: The formula is eco-friendly and protects electronic components from corrosion by reducing the corrosiveness that halogens can cause.

• High-temperature resistance: It is designed to perform well under the high temperatures typically used for soldering electronics.

• Non-conductive and insulating: The flux is non-conductive, which ensures the safety of circuits during and after the repair process.

• Versatile application: It is suitable for a variety of small electronics projects, including mobile phone disassembly and BGA (Ball Grid Array) repair.

• User-friendly packaging: The product is often sold in compact bottles with a syringe-style dispenser for easy and precise application. 

Function of flux in soldering

The purpose of a flux like YCS No. 1 in soldering is to: 

• Clean the surface: It removes oxidation and other impurities from the metal surfaces to ensure a strong, reliable connection.

• Prevent re-oxidation: It creates a protective barrier that shields the molten solder and metal from oxygen during heating.

• Improve flow: It helps the molten solder flow smoothly and evenly across the surface.
