Sn-0.7Cu无铅焊锡丝

Tin wire is mainly composed of two parts: alloy and flux. The alloy composition is divided into tin lead and lead-free, which is generally designated by customers; The choice of flux (generally referred to as "rosin") is to select different solder wires according to different use process and different materials to be welded. After years of practical experience, the company has developed various tin wires with different formulations for customers to choose. Each formula has different effects. Customers should recognize the product number when selecting, Avoid unnecessary quality problems.
The alloy composition is divided into tin lead alloy, lead-free alloy, and its proportion corresponds to the tin strip. The alloy model is selected according to the customer's demand.
V-series rosin type: it is suitable for electronic repair welding of electronic class and related components. It has high residual impedance and no leakage after welding. It can pass high-pressure test, and is a common tin wire in electronic industry.
M series washfree type: suitable for repairing welding PCB board such as less residue, high absolute impedance and clean surface.
N series nickel plating type: suitable for welding hard materials such as nickel, surface nickel plated components, wire, terminals, socket lamp and other hard materials.
S series welding type: suitable for high and middle-grade watch, bracelet table, chain, chest, shoes, hair clip and other zinc alloy accessories.
T series special tin wire: suitable for welding stainless steel, zinc alloy, aluminum lamp head, etc. this kind of flux is non rosin type, and the residue can be cleaned with water after welding.
Solid core tin wire: This product is solid core, without flux, suitable for fuse, metal pipe and other special purposes.
