Lead free solder wire has a higher temperature of 217°C - 221°C melting point. It has played some vital roles in the reduction of the sizes of miniature gadgets. A highly compact board designed with lead-free solder wires has few faults. They hold the advantage over the lead based solder wire.
Product Knowledges
The fluxes in Zhongshi's unique cored solder wire products have been formulated to accommodate a wide variety of different alloys, cores, and diameters. cored wires support both traditional tin-lead manufacturing, as well as modern Pb-free processes, including point-to-point robotic soldering. Award-winning cored wire ensures even distribution of flux throughout the wire and is available in Pb-free, high reliability 90iSC alloy, SnPb, and halogen-free formulas. For assemblers who prefer a non-cored option for selective soldering applications, solid wire products are offered in both Pb-free and SnPb options.
Solder wires have an extensive set of uses in a broad range of industries ranging from consumer electronics to industrial bonding of metal substrates. To ensure flexibility across all applications, our lead-based and lead-free solder wires offer:
- Broad range of melting points
- Durable mechanical bonding
- Range of diameters
- Low oxide formulations
- Formulations for both manual and automated processes
