Description
Ulbrich WCD110 Silver Tinned Solar Tab Wire 5mm x 0.25mm x 638M 96.5/3.5 Sn/Ag
The Ulbrich WCD110 is a silver tinned copper solder tab wire manufactured by Ulbrich Solar Technologies for photovoltaic cell tabbing and interconnect applications. This is a full 638-meter spool of 5mm-wide flat ribbon wire, coated with a 96.5% tin / 3.5% silver solder alloy to a plating thickness of 10–17.5 microns. The copper core (alloy designation CD110) provides excellent electrical conductivity, while the Sn/Ag solder coating is designed to bond reliably to solar cell busbars during automated stringing and tabbing processes.

Applications
Solar tab wire is a core consumable in photovoltaic panel manufacturing. It is used to interconnect individual solar cells within a module by soldering flat copper ribbon strips across the busbars on the front (negative) face of one cell to the back (positive) face of the next, creating a series circuit. The 5mm width and 0.25mm thickness of the WCD110 suit standard crystalline silicon (mono and poly) cell formats. The 96.5/3.5 Sn/Ag solder alloy is a lead-free formulation widely used in PV manufacturing to meet RoHS compliance requirements. Ulbrich Solar Technologies is a recognized supplier of precision-rolled flat wire and ribbon products to the solar industry, and their tabbing wire is used in both manual soldering operations and automated stringing machines. This spool format is compatible with standard tab wire dispensing equipment used in solar panel assembly lines and repair shops.
This Ulbrich WCD110 Silver Tinned Solar Tab Wire is new and unused. The spool is intact with its original protective film in place. The label confirms a plating date of 06/21/2016, lot number U0004273AAAA, and a measured length of 638.861 meters. Please view our photo set and contact us if you have any questions.
