(Waterbury, CT USA) – May 29, 2019, the Assembly Division of MacDermid Alpha Electronics Solutions, a world leader in the production of electronic soldering and bonding materials, will be presenting a technical paper on “Prevention of Weak Solder Joint Formation in Multi Busbar (MBB) Interconnection” during the SNEC 13th (2019) International Photovoltaic (PV) Power Generation and Smart Energy Exhibition & Conference taking place June 3-6 in Shanghai, China.

The paper “Prevention of Weak Solder Joint Formation in Multi Busbar (MBB) Interconnection” will be focus on addressing the factors affecting reliability of solder joints in MBB technology. “In multi Busbar (MBB) interconnection, between 6 and 15 round copper wires are soldered onto more than 50 solder pads on the front side of the solar cell. This approach reduces silver consumption for the front side metallization and increases the module efficiency by lowering series resistance and improved light harvesting.” said Narahari Pujari. “However, due to reduced cross sectional area of silver pad and wire, reliability of solder joints remained one of the biggest concerns in this technology. Lowered peel strength, wire crippling and cold or dry solder joint formation are the most common issues.” Therefore, Pujari’s presentation is going to review and analyze the formation of weak joints and ways to obviate the same.
