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.

There are a variety of reasons behind pads getting "lifted" completely or partially from the laminate of a PCB. Per the just revised IPC-A-610 Revision G, a defect for all three classes occurs when the land is lifted up one or more pad thicknesses. Lifted pads can occur when a device has been improperly removed or there is a manufacturing defect in the board construction. In any case, as with any repair, the ultimate decision on the ability to repair the pad lies with the customer.
Another year is over in the SMT industry. 2017 saw a myriad of hot topics, including Industry 4.0, the millennials’ entry into the manufacturing space, and alternative solder materials, to name a few. Without further ado, here are the Top 10 columns from SMT007 over the past year.

The ongoing miniaturization trend in the SMT production induces new challenges and highly integrated systems. In passive components, the miniaturization leads to the introduction of the EIA size 01005 or smaller. Despite numerous publications in this field already addressing the printing of such devices, a defined wholly optimized process remains unsolved and inspires further novel research ideas on this topic.
