It is a no-clean solder paste specifically designed for robustness in reflow. As excessive growth of intermetallic compounds affects the mechanical integrity of solder joints negatively due to their brittle behavior, 90iSC alloy permits maintaining a stable interconnection with more than 75% original solder joint strength after thermal cycling. Lead-Free Reflow Soldering Ingredient of alloy in solder paste applied for lead-free reflow soldering mainly includes: a. Kester EP256 is a paste solder developed for high volume SMT reflow soldering. HARIMA offers a complete range of MULTiCORE solder paste solutions in the 90iSC alloy which are capable of exceeding the challenges of harsh environments. This, in combination with its solderability when integrated with the appropriate flux system, makes 90iSC alloy the world’s leading high reliability, lead-free, solder alloy. Reflow soldering is a process by which the solder paste is heated and changes to a molten state in order to connect components pins and PCB pads together. Reflow soldering is a process that uses a solder paste, a remarkably sticky mixture of powdered solder and solder flux, to temporarily attach components to. When subjected to thermal cycling, thermal shock, and thermal ageing, 90iSC alloy is unmatched. Use controlled heat to reflow the solder paste into a molten state this creates permanent solder joints. 90iSC alloy has the ability to provide high creep and strain resistance within operating temperatures up to 150☌. Solder paste, a mixture of powdered solder and flux, attaches many small electrical elements to a contact pad. ![]() ![]() Tough, durable, adaptable, and high-temperature capable, 90iSC alloy is the lead-free benchmark for high reliability applications. When traditional SAC alloys can’t deliver safety-critical performance, HARIMA’s 90iSC alloy is the answer. Join our mailing list to get future updates on new reflow oven & reflow soldering technologies Leave this field empty if youre human: Terms. HARIMA’s 90iSC alloy was designed for applications and markets where extreme temperature resistance and reliability are non-negotiable and lead-free compliance is required. Superior Flux offers a full range of solder pastes for SMT reflow applications, including: conventional and low-residue No-Clean, water-soluble (including a.
