Lead-free Solder bar and variety

Lead-free Solder bar

Integrating researching and practical experience in producing solder bars for many years, combining environment protection development direction of modern electronic industry and demands of reliability product, the company produces lead-free tin bars with high purity metal raw material. Under strict quality control, the company  fectively control the impurity content of oxidizing metal and nonmetal, and the tin

bar shows smooth surface, quite high purity, fine flowing after fusing, wonderful wettability, polishedsoldering spot, little oxidizing rubbish and so on. It is suitable for wave welding and hand welding that is required high quality, Thousand Island continues to research and develop, in order to supply lead-free solder bar of kinds of alloy scales and types for customers.

  Guide points of lead-free welding

In order that you can smoothly perform lead-free process, Qianli supplies some key points about using the lead -free solder before you use the lead-free assembly, we wish these key points can be helpful for you production. wish these key points can be helpful for your production;

  Please choose Sn/Ag/Cu, Sn/Cu, Sn/Ag alloys,because these alloys are the best euectic alloy of lead-free solders, and can greatly withstand the lead interfusion, even, they are more suitable for step-by-step lead-free processing of whole material.

  Check the temperature-control stability of lead-free equipment, to make sure the lowest temperature difference during welding.

  Improve wetting ability of lead-free solder through taking use of die plate tapping equipement, nitrogenwelding environment and higher active soft solder.

  After welding, please pay attention to checking the electric performance, stress of butt-welding material, thermal faigue, creeping and damage for mechanical vibration.

Make sure the material alloy and thermal resistance are matching with solder.
