PRODUCT FEATURES
Containing very little plumbum (≤ 100 ppm), the lead free solder meets increasing demands for environmental protection around the world and gradually replaces the traditional tin-lead solders. Generally, Pb free solders are widely used for soldering electronic components, computer parts, copper plates, PCBs, TV parts, radio components and other metal equipments. We offer multiple kinds of soldering alloys, including Sn-Cu, Sn-Ag-Cu, Sn-Ag, Sn-Bi, and so on.
1. Lead free solder is featured by good welding performance, short wetting time, outstanding anti-oxidizability and high tensile strength.
2. During welding, little nocuous volatile gas and flux residue generate; besides, very little soldering splatters around.
3. Solder spot is bright and reliable for welding.
4. Resin in the Pb free solders is uniformly distributed and featured with good continuity.
5. Our lead free solder possesses small surface tension and large flow ability.

1. Choose the Solder Composition Lead or Lead-free is the first thing to be considered. Then, choose the right solder according to the working temperature. Generally, solders used at high temperature are available for easily accessible connections, while the ones at low temperature are for smaller and crowded connections. Next thing is to choose right solder alloy. Commonly, the most common lead free solder contains 95% tin and 5% antimony. Its smelting point is between that of 40/60 and 50/50 tin/lead solders.

2. Select Right Diameter of Pb Free Solders Select solder wires whose diameter is between 0.01 inch (0.25 mm) and 0.125 inch (3.25 mm). If the solder diameter is too small, the solder will be melted very fast, and vice versa. So, over-thin solder will result in lack of soldering, while the over-think solder will absorb too much heat and damage the welded components.

3. Select Flux Core for Lead Free Solder Choose the flux cores according to your personal style in applying flux.
