Indium Corporation offers flux cored solder wire used in hand soldering and automated processes during photovoltaic module assembly operations. CW-807 is a standard no-clean flux with clear residues and is available with Sn/Pb, Sn/Pb/Ag and SAC305. Manufactured at Indium's Chicago facility, which employs the most modern equipment and experienced work force, our flux-cored wire is void-free, made with tight dimensional tolerances, operator friendly and widely adopted by PV module manufacturers worldwide.
Solder Wire from the Indium Corporation is made to demanding quality standards. Our flexible manufacturing process allows us to fulfill orders from evaluation/research quantities to full scale production volumes. We offer over 100 alloys in various diameters.
Indium Corporation solder preforms are used extensively in CPV applications to mount III-V silicon dies, bypass diodes and to provide a metallic thermal interface when mounting CPV receiver substrates to a heatsink. Our solder preforms are in the field today in thousands of CPV modules around the world and standup to IEC standards including CPV thermal cycling demands.
Preforms come in custom and standard shapes such as squares, rectangles, washers and discs. Dimensions can be held to tight tolerances to assure volume accuracy.
A wide assortment of alloys is available in liquidus temperatures that range from 47°C to 1063°C. Alloys can be indium-contained, gold-contained, lead-free, fusible or standard tin-lead, as well as many others.

Previously we discussed the importance of dimensions and tolerances in the specification of solder preforms, however these data points are best expressed in the form of an engineering drawing. You may be thinking, “Why would I make a drawing for a rectangle?”. Even if you are specifying a…
A wave solder machine's foam fluxer is a device in which compressed air is fed through a porous tube (commonly referred to as a "stone" because this part used to be made out of unglazed porcelain) that is submerged in foaming flux. The stone is covered with a chimney which helps produce…
Packaging is an extremely important part of specifying solder preforms. Not only does packaging affect the price of the order, it also effects how the individual preforms will be presented to your operators or automation. Most importantly though: packaging protects the products throughout shipment and…
