SHENMAO America, Inc.’s Joint Enhanced Solder Paste (JEP) PF606-EP305 offers the advantages of both conventional solder paste and anisotropic conductive paste, i.e., self-alignment and planar insulation, respectively. JEP enables soldering and joint encapsulation in one step reflow.
The new epoxy-based solder material is designed for very fine pad size (70 μm) soldering, especially for advanced display packaging and assembly. It is compatible with various surface finishes, with a transparent residue and no cleaning required.
SHENMAO’s JEP is eco-friendly with both lead-free and halogen-free. Halogen can generate hazardous gas at high temperature and the use is restricted. SHENMAO halogen-free JEP materials meet J-STD standard (≦1000ppm Chlorine/ ≦ 1000ppm Bromine) and IEC standard (≦900ppm Chlorine/ ≦ 900ppm Bromine/ ≦ 1500ppm Total halogens).
SHENMAO has successfully been approved by many international well-known electronic manufacturers. The company strives to offer the best quality without compromising cost and time-to-market while providing maximum value to all customers. SHENMAO America, Inc. blends SMT solder paste at its facility in San Jose, CA for distribution in North America.

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.
