Laser welding solder paste
In laser welding temperature lead-free solder paste

HX - WL527 temperature in laser welding solder paste is designed for today's fast welding production process of a kind of no clean type of solder paste, the use of tin bismuth silver series lead-free alloy solder powder of low melting point and the mixture of solder paste, suitable for rapid laser welding equipment and the HOTBAR, welding time shortest can reach 300 milliseconds. This product quickly without solvent volatilization in welding process, welding beads no residual after, can eliminate completely remove solder beading process; This product belongs to zero halogen formula at the same time, few organic residue, and are transparent, surface impedance is high, high reliability; Can adapt to the dispensing, transfer printing and needle and other craft.

Optimal point

1. This product is a halogen free solder paste, environmental protection, few residues, without cleaning after welding.

2. Low temperature alloy, can effectively protect the PCB and electronic components, highly active, suitable for welding on the surface of the nickel (Ni).

3. Good printing roll and fall tin, to as low as 0.3 mm spacing between the solder can also complete the fine print;

4. Continuous printing, its viscosity changes little, steel can be online operation life is long, more than 8 hours still not dry, still keep good printing effect;

5. After only a few hours printing still keep its original shape, basic no cave, SMT components won't produce deviation;

6. With excellent welding performance, can be in a different part of the show proper wettability;

7. Can adapt to the requirement of different class welding equipment, do not need to complete welding in nitrogen filled environment, in a wide range of reflow furnace temperature still can show the good welding performance.
