Indium Corporation will feature its MEMS microphone lid-attach Indium8.9HF Solder Paste at MEPTEC’s 15th Annual MEMS and Sensors Technology Symposium on June 6, in San Jose, California.
Indium8.9HF is a no-clean, halogen-free (no intentionally added, halogen-free flux) solder paste that enables dispensing of fine lines and shapes down to a width of less than 150 microns. Indium8.9HF provides reliable and consistent dispensing of a standard racetrack deposit using automated time/pressure or auger-based dispensing equipment.
Indium8.9HF eliminates failure modes, such as blow-hole, reduces solder creep, and increases solder joint shear strength. The flux is suitable for use with all standard Pb-free higher-melting alloys, such as those based on SnSb and SnAg.

A new generation of near microscopic size SMT chip capacitors has appeared in the market, known as either 0201 or 008004. This article investigates and characterizes the stencil printing process for compatibility with M0201 capacitor assembly. Effects of circuit board quality, stencil thickness, and stencil nano-coating are evaluated against solder paste volume transfer efficiency and raw-volume print distribution.

AOI has an invaluable role to play in speeding up the process of PCB production, in ensuring extreme precision to catch even the smallest of defects, and in minimizing the potential for time-consuming and costly reworking.
