Qian tian tin solder factory for best quality lead-free solder products, and ensure the compliance with pure tin and fine production technology, qian tian tin solder factory under strict IQC incoming inspection management, the quality of each batch, all must after German imports of metal direct reading spectrometry instrument Spectolab computer analysis, you just need to moment will be the percentage of each ingredients fully displayed, to ensure that raw materials meet the requirements of the highest quality (100 PPM or less than 50 PPM). The company research and development of lead-free solder has unique advantages: & have spent 1, lead-free solder surface smooth, high purity, good liquidity, after melting excellent wettability, bright spot, oxidation residue content rarely; & have spent 2, low costs, excluding the high prices of precious metals; & have spent 3, to adapt to the current existing wave soldering equipment and components to withstand temperature; & have spent 4, low sensitivity to the impurity element; & have spent 5, when cooling surface concave and convex phenomenon less; & have spent 6, the reliability of solder joint reliability than traditional SnPb tin-lead solder.
