           Product Description

          Surcoat T / TX is an organic copper protective agent that has excellent heat resistance and moisture resistance properties. It is a water-soluble preflux specifically designed for heat and welding resistance of lead-free (Sn / Cu / Ag) solder surface of the printed circuit board.

          Surcoat T / TX is also an organic OSP specifically designed for the lead-free soldering process that can withstand the impacts of high-temperature lead-free soldering (Peak Temp. 260 ℃, 3 times or more) several times and still retains excellent copper solder surface resistance (0.9 ~ 1.1? aperture PTHs, 99 ~ 100% rate on the tin).



           Product Advantages
          low manufacturing cost, extend the life of the bath
          Surcoat TX is suitable for copper/gold mix board, and can    operate without taping
          excellent flatness and pore uniformity
          bath solution is less prone to crystallization and does not    produce oil
          suitable for surface copper treatment of wafer package
          great heat resistance -(260℃/ IR-Reflow more than 3 times)
           
          short processing time for T/TX bath
          maximum allowable limit of copper ions in a bath
          comply with environmental requirements
          compatible with disposable processes
          simple procedures and reduces cost
