TopLine will exhibit a range of CCGA PCBA assembly solutions at NEPCON China Shanghai, in stand #1F04, April 24-26. This will be TopLine’s 6th straight year at NEPCON China Shanghai. Featured products will include CCGA - Column Grid Arrays and Daisy Chain BGA test vehicles. TopLine’s CCGA Column Grid Array IC packages are made with non-collapsible solder columns for surface mount soldering on printed circuit boards (PCBs) and provide more compliancy than solder balls (Ball Grid Arrays or BGAs) to absorb stress and increase solder joint reliability under harsh operating conditions. “Many people are still unaware of the benefits that solder columns provide to reduce stress caused by CTE mismatch when interconnecting area array packages and the PC board,” states Martin Hart, TopLine CEO.
NEPCON China Shanghai 2019 will be held April 24 – 26 at the Shanghai World EXPO Exhibition & Convention Center. NEPCON China is a prestigious professional trade platform and exhibition on SMT (surface mount technology) and EMA (electronics manufacturing automation). It brings together more than 500 renowned brands and 30,000 local and international visitors. TopLine has been active in promoting its products in the China market for more than 20 years.
TopLine manufactures a wide range of Daisy Chain test components, Column Grid Arrays, Particle Impact Vibration Dampers and engineering evaluation kits for process development, experimentation, machine evaluation, solder training, and SMT assembly practice. TopLine products provide hands-on learning for engineers. Contact TopLine

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.
