![]() ![]() Good thermal and electrical conductivityįor more information about Durafuse ® LT, please download our product data sheet.Good mechanical shear strength up to 150-165 ☌.The weight of the small chip itself, combined with the pressure, causes the separated molten solder paste to emerge from beneath the body, forming tiny solder beads along the edges. Excellent drop shock reliability – comparable to SAC During the reflow processes, the lack of soldering pads beneath the middle of small chips allows the molten solder paste to escape.Durafuse ® LT is ideal for high-reliability applications which utilize thermally sensitive components. The SnInAg alloy initiates joint fusion while the SAC alloy provides enhanced strength and durability. SMT Board Assembly Process Recommendations. The required peak reflow temperature is under 210 ☌. Durafuse ® LT is made up of a low-melting indium-containing alloy and a higher-melting SAC alloy. Durafuse ® LT provides improved drop shock resilience, outclassing bismuth-tin (BiSn) or bismuth-tin-silver (BiSnAg) alloys, and performing better than SAC305 with optimum process setup. Read Moreĭurafuse ® LT is a patented two temperature alloy system designed to provide high-reliability in low-temperature applications. Read More How to Calculate the Metal Mass Fractions in a Two-Metal Alloy Systemįolks, I was surprised to see the wrong formula for metal alloy density calculations on YouTube. ![]() Read More Excel Software Tool to Determine Mass Fractions in Binary Alloyįolks, Recently, I posted a derivation of the equations to determine the mass fractions of two metals in a binary alloy. This historical record unmistakably brought home the “inconvenient truth”: global warming is upon us, for real – not in the future, but right here, right now. This summer, the temperature reached 111☏ in Silicon Valley, where I live. Read More Materials Science Solutions for Electronics Sustainability Read More Low-Temperature Solder for Environmental SustainabilityĪs energy consumption has become increasingly important-in terms of cost, availability, and environmental impact-it is about time we use quantitative data to consider carbon emissions and oven energy consumption to make process decisions. In the world of electronics assembly, the utilization of high-quality alloys is critical to a successful product, and is verified through accurate and precise a. ![]()
