Concentrated solar energy (CSE) is being used for material processing. In this work, CSE is applied for soldering and named as the “Concentrated Solar Energy Soldering (CSES) technique”. A Fresnel lens along with a two-axis sun tracker to concentrate the solar energy required for soldering is used. Cu substrates are soldered with CSES technique using SAC 305 &amp; SACX 0307 lead-free solders. Feasibility study along with the initial results are discussed. CSES technique, a green technology is found to be encouraging. The CSES technique can be used to solder on-site electronics components used in nuclear, space, automobiles, computer hardware, electronic circuits used in process equipment's, etc. Specifically, in the remote areas CSES will be useful to solder various components, circuits, etc.

Novel “Concentrated Solar Energy Soldering (CSES) Technique” - a Feasibility Study

IEEE - Fifth International Conference on Science Technology Engineering and Mathematics (ICONSTEM) 2019

In this study, “Concentrated Solar Energy (CSE)” is applied for soldering and is named as the “Concentrated Solar Energy Soldering (CSES) technique.” Lead-free solders are used for comparing novel CSES technique solder joints with CSI (Conventional Soldering Iron) solder joints. Tensile strength, bending/flexural strength, microhardness, electrical resistivity, fractography, optical microstructures, SEM microstructures, and EDS analysis were used to compare CSES solder joints with CSI solder joints. The salt spray test (SST) was used for corrosion analysis of CSES and CSI solder joints. Experimental results reveal that the tensile response, bending strength, and microhardness of the CSES solder joints were almost equal to those of the CSI solder joints. It was observed that after corrosion, the tensile strength, bending strength, and microhardness for CSES and CSI solder joints reduced. CSES solder joints were found to be slightly better than CSI solder joints for electrical resistivity. Electrical resistivity for all the cases studied was found to increase slightly after corrosion. Interfacial integrity and effect of corrosion were clearly observed on CSES and CSI solder joint microstructures. The intermetallic compounds (IMC) formed in case of CSES solder joints were found to be having slightly less thickness than that of CSI solder joints. The results demonstrate CSES technique as a green technology and a potential substitute to the CSI method.

Microstructure, Mechanical, Electrical Properties and Corrosion Analysis of Lead-Free Solder CSI Joints on Cu Substrate Using Novel “Concentrated Solar Energy Soldering (CSES) Method

Solar energy, which is available in abundant in nature, is least utilised. As per primary energy product, solar energy conversion can be of three different ways: solar fuels, solar electricity, and solar thermal systems. These three approaches are presently not being fully utilised. Concentrated solar energy (CSE) is an alternative to other types of energy for modifying the surfaces of metallic materials. Attempt has been made to overview the current status of CSE in materials processing technology. In this paper, applications of CSE through solar furnace and Fresnel lens for hardening, coatings, sintering, nitriding, synthesis and welding are discussed.

Concentrated solar energy in materials processing

Overview of the present-day concentrated solar energy (CSE) technologies is presented. Approaches to concentrating solar energy are reviewed and the current projects worldwide of CSE technologies are compared. This paper presents general descriptions, current projects and summary of the CSE technologies. Parabolic trough collectors (PTCs) technology is found to be a mature technology. The linear Fresnel collectors (LFCs) technology is still in the experimental stage. The tower solar power (TSP) technology is preferred for large scale due to the cheapness. Sterling/dish collectors (SDCs) technology is designed especially for remote applications and has the highest overall efficiency and the highest operating temperature. The application areas show that CSE can be used in a wide variety of systems, could provide significant environmental and monetary benefits.
