Micro Electron Mechanical Systems (MEMS) refers to micro-devices and systems that consist of micro-sensors, actuators, signal processing, mechanical structures, and other devices. MEMS include optical perception, environmental perception, displacement perception, acoustic perception, communication networking, interactive recognition, etc. The products of MEMS include accelerometers, gyroscopes, micro microphones, RF MEMS, pressure sensors, micro flow meters, etc. MEMS is applicable in smartphones, computers and tablets, smart TVs, remote controls, gaming devices, robots, wearables (including smart watches, active noise-canceling headphones), smart homes, smart buildings, IoT, automotive, transportation, industry, healthcare, smart city, military, and other fields. Compared with integrated circuit packaging, MEMS has a wide variety of cavities and micro-mechanical structures, which introduces extra requirements on packaging materials. MEMS packaging includes Die Level Packaging, Device Level Packaging, Wafer Level Packaging, Single-Chip Packaging, and System in Package. Fitech provides reliable solder and solution support for MEMS packaging in various fields.


The alloy composition of eutectic gold-tin solder paste for MEMS packaging consists of 80%wt of gold and 20%wt of tin (Au80Sn20). Under the impact of the excellent characteristics of the FH-280 product and Fitech’s advanced powder manufacturing technology, Fitech’s gold-tin solder paste has many advantages such as high tensile strength, excellent corrosion resistance, superior thermal creeping performance, and premium compatibility with other precious metals. It also has extraordinary electrical conductivity and thermal conductivity. The MEMS packaging gold-tin solder paste (T3-T6) has a melting point of 280℃, supporting the printing and dispensing process.
