The IPC Hand Soldering and Rework Championships took place on the expo floor at IPC APEX EXPO live, January 31, 2019, in San Diego, USA.
The official competition roster boasted twelve competitors from around the globe, and the competition was close indeed. With less than 13 minutes separating all competitors’ raw times, the competition director, IPC’s Kris Roberson commented that much of the final rankings boiled down to work accuracy.
The top three finishers are:
1. Ryosuke Matsunami (Japan)
Completion Time: 1:14:13
2. Wenji Zhang (China)
Completion Time: 1:15:00
3. Le Van Linh (Vietnam)
Completion Time: 1:14:00
Be sure to get your copy of I-Connect007’s Real Time with IPC APEX EXPO Show & Tell Magazine later in February for complete coverage of the competition, including full results, photos and video.

The interdigitated back contact (IBC) is one of the methods to achieve rear contact solar cell interconnection. The contact and interconnection via rear side theoretically achieve higher efficiency by moving all the front contact grids to the rear side of the device. This results in all interconnection structures being located behind the cells, which brings two main advantages. First, there is no frontside shading of the cell by the interconnection ribbons, thus eliminating the need for trading off series resistance, losses for shading losses when using larger interconnection ribbons. Second, a more homogeneous looking frontside of the solar module enhances the aesthetics.

Solder defects in surface-mount technology (SMT) assembly have been an issue for decades. Further, the combined challenges of Pb-free soldering and ever-increasing miniaturization have resulted in new or exacerbated defects in electronics assembly, but there are proven ways to avoid defects. This book will be especially beneficial to PCB assemblers in improving their assembly processes and the reliability of the end-product, eliminating field failures, and reducing costs.

At the SMTA Dallas Expo, Andy Shaughnessy sat down with Miles Moreau of KIC to discuss the company’s latest offering in wave process inspection technology. Miles also explains how KIC’s early focus on automated real-time process monitoring has enabled them to become a leader in Smart factory implementation.
