Sn5Pb95 | High melting point Solder Spheres

LINQALLOY Sn5Pb95 is a tin lead alloy with a very high liquidus point and a small transition phase. Even though the world is moving away from Lead for consumer electronics, there are still applications that cannot be supported with Lead Free alternatives due to their high operating temperatures. For those limited cases, we offer the Sn5Pb95 solder spheres that have an extremely high melting temperature. Industries like automotive and manufacturing need to rely on these solutions until a fully qualified and functional alternative is developed.

Features:

• Liquidus Melting Temperature of 322°C (611°F)
• Ideal for High operating temperature applications
• 10°C transition range

Each jar has a clear label on the lid specifying the solder ball diameter as well as a label on the front identifying the alloy type, the quantity of spheres in the jar, the date of manufacture, and the product lot (or batch) number. This batch number is tied to a certificate of conformance that is also provided with the solder spheres and ensures the Sn5Pb95 solder spheres meet the following quality criteria:

• Tin (Sn): 5%
• Lead(Pb): 95%
• Liquidus Melting Temperature: 322°C
• Sphericity: Within 1.5%
