Minimizing Micro-cracks in Solar Cell Interconnection During Manual Soldering

From OK International, Inc.

Solar cell substrates are delicate. The manual soldering process applies stress to the material which can cause micro-cracks to form. This article identifies the requirements and equipment needed to reduce the microcracking during solar cell assembly.

Products & Services
Soldering Irons, Stations, and Accessories
Soldering irons, stations and accessories bond two or more metallic surfaces together with a low melting alloy solder such as tin/lead or Sn/Cu/Ni/Ge alloys, which is melted, wets the surface and resolidifies forming a soldered joint.
