MEMS (Micro-Electro-Mechanical Systems) realize sensing, actuation and signal conversion via miniature precision structures. Featuring tiny cavities and fragile architectures, they demand extremely high cleanliness, low stress and minimal residue for solder interconnections. Widely deployed in sensing, acoustic, optical and inertial measurement applications, soldering quality directly determines hermeticity, signal accuracy and long-term stability of devices.

Industry Challenges & Solutions

MEMS components are sensitive and fragile. Common risks include cavity contamination by flux residue, structural deformation induced by stress, voids and hermetic failure; conventional solders tend to damage microstructures. 

Huaqing supplies low-residue high-purity solder pastes, precision solder preforms and dedicated fluxes compatible with vacuum, formic acid reflow and TCB processes. With controlled residue and low stress during soldering, our materials protect delicate microstructures and support hermetic interconnection and stable performance of MEMS devices.
