Supply units Tin Tin Factory [TTIN brand] green tin wire / Sn-Cu0.7 / green tin wire / environmental solder wire 
 Taiwan Tin Tin (Group) Co., Ltd. 99.99 Malaysia ingredients environmental pure tin ingots as raw material, equipped with high-tech multi-element environmental composite flux and advanced production technology to produce full compliance with the EU ROHS standard of environmental protection lead solder, from pure tin to the rigorous process of selection of superior quality monitoring, to final product shipment inspection, and are fully guaranteed lead-free solder wire, high weldability and its quality. In the early 1990s, for a strong EU environmental awareness through ROHS Act limits the use of lead, and specified to run from July 1, 2006. Taiwan Tin Tin (Group) Co., Ltd. invested a lot of research and effort, since 2003, mass production of lead-free solder series products, and compliance with international environmental requirements. The EU RoHS directive have two harmful substances Pb (lead), Cd (cadmium) content is far below the internationally accepted standards. 


 Solder wire: 
 Tin wire consists of two parts: alloy and flux. Alloy composition is divided into a tin-lead, lead-free, generally designated by the customer; flux (commonly referred to as "rosin") to select the customer's use of technology, different welding materials to choose different types of flux solder wire, the Company after years of practical experience to develop a variety of formulations flux solder wire for customers targeted selection, each recipe has a different effect, customers in the selection of a clear understanding of product numbers, to avoid unnecessary quality issues. 
 Alloy type: alloy composition is divided into a tin-lead alloy, lead-free alloy, the composition ratio of tin Correspondingly, based on customer needs to select the appropriate alloy model 
 Types of grades of alloy composition (wt%) grade alloy composition (wt%)

 Flux (rosin) type and use: 
 Type of use of the flux (rosin) 
 V-Series rosin applies to electronics and related components, electronic welding, welding residues impedance, leakage through high-pressure test is the most commonly used solder wire in the electronics industry. 
 M series disposable requires residues, high insulation resistance, and a clean plate surface of PCB welding. 
 Welding of the N series of nickel-plated type nickel material, the surface of nickel-plated components, wire, terminals, sockets, lamp and other hard materials. 
 The S series guns welding type of high profile watch, bracelet tables, sets of chains, brooches, shoes, flowers, hair clips and other zinc alloy jewelry burn weld fill processing. 
 T series of special solder wire for welding of stainless steel, zinc alloy, aluminum lamp, such flux non-rosin residue can be washed after soldering. 
 The product is the real core of the solid core solder wire, flux-free fuse metal pipe fittings and other special purposes. 

 Diameter: 
 Tin wire diameter from 0.3mm to 5.0mm can be based to customer demand, usually equipped with: 0.3 mm, 0.5 mm, 0.8 mm, 1.0 mm, 1.2 mm, and other specifications.
