Lead-free solder wire series

The environmentally pure tin ingots

free solder wire Malaysia ingredients up to 99.99 for the use of raw materials, the application of computer motherboards, computer peripherals, communication products, household appliances, medical equipment, power strips, UPS, etc.: lowest melting point, tensile strength and high shear strength, wettability, suitable for high-end electronic products or the high demands of electronic, electrical industrial use.

Product Description:

1, electrical conductivity, and excellent thermal conductivity performance, the speed of the tin.

2, good wetting properties.

3, rosin content is moderate, the operation will not splash of rosin.

4, Rosin announced uniform, no broken rosin tin core.

5, odor-free, odorless, non-toxic to the body of the smell, smoke less, with a touch of green flavor.

6, cable tidy, beautiful, bright surface

Tin thread diameter: tin thread diameter: 0.3mm, 0.5mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm

Flux (rosin) type and use:

type of flux (rosin) purposes
V Series rosin suitable for the electronic repair welding of electronic components, high impedance of residue after soldering, no leakage through the high-pressure test, solder wire is most commonly used in the electronics industry.
M series disposable for applications that require less residue, high insulation resistance, the board clean PCB board repair welding.
N series of nickel-plated type the nickel material suitable for the welding of nickel-plated surface components, wire, terminals, sockets, lamp and other hard materials.
S series guns welding apply to high profile watch, bracelet table, set of chains, brooches, shoes flower, hairpin zinc alloy jewelry burning weld fill processing.
T series of special solder wire applicable to the welding of the stainless steel, zinc alloy, aluminum caps and other such non-rosin type flux residue can be washed with water after soldering.
solid core solder wire product is solid core, excluding flux is applied to fuse, metal fittings and other special purposes.

Lead-free solder wire advantages and Scope

The company’s production of environmentally friendly lead-free solder wire with excellent welding performance, less residue after welding, non-toxic and non-corrosive flux no splash, no bad smell, does not cause harm to humans, the product is suitable for hand- repair welding and drag soldering, automatic machine welding.
