Indium Corporation will feature Indium11.8HF-SPR Solder Paste, a new air and nitrogen reflow, no-clean, Pb-free solder paste designed to meet the fine feature printing requirements of mobile manufacturers, at IPC APEX EXPO 2018, which will be held February 24–March 1 in San Diego, California.
Indium11.8HF-SPR specifically addresses customers’ needs for Type 5 powder. This new solder paste delivers unprecedented stencil print transfer efficiency on the broadest range of processes, while maintaining industry-leading reflow performance.
- Halogen-free per IEC 61249-2-21 test method EN14582
- High-transfer efficiency through small apertures (≤ 0.66AR)
- Long stencil life (>12 hours)
- Eliminates hot and cold slump to inhibit bridging and solder beading defects
- Avoids the potential for HIP and graping defects with a unique oxidation barrier
To learn more about Indium11.8HF-SPR, visit Indium Corporation at the show at booth #1625.

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.
