Product Introduction of Almit DB-ZERO LFM-48M 3.5%
Almit DB-ZERO LFM-48M 3.5% is a specialized resin flux-cored solder wire manufactured by Nihon Almit Co., Ltd., designed for high-reliability soldering operations .
This soldering material features the LFM-48M alloy, a precise composition of Tin (Sn), 3.0% Silver (Ag), and 0.5% Copper (Cu) . The wire integrates the DB-ZERO flux core with a nominal flux content of 3.5% (ranging from 3.0% to 4.0%), ensuring consistent wettability . With a melting profile characterized by a solidus temperature of 217°C and a liquidus temperature of 221°C, this product is engineered to meet rigorous industrial standards . It is available in a wide range of wire diameters, from 0.3 mm to 1.6 mm, and has a shelf life of up to 2 years from the date of manufacture .
