Ribbon and Foil
High quality Solder Ribbon and Foil manufactured by Indium Corporation is available in many standard alloys and sizes. Material can also be custom made to your unique material and dimensional requirements.
Solder Ribbon is supplied in continuous lengths and is packaged on spools. Solder Foil is supplied in sheet form.
Whether you are looking for large quantities of Solder Ribbon in specific widths and thicknesses for automatic die bonding, or a few feet to do testing, Indium Corporation can accommodate your needs.
Our capabilities allow us to manufacture widths as small as .020" (.5mm) and up to 3" (76mm). Thicknesses range from .001" (.025mm) up to as thick as your application requires. All dimensions are dependent on the properties of the metals involved.
We can work with you on your specific dimensional requirements. Our typical tolerances are:
|Up to .099" (2.5mm)||+/-.010" (.254mm)|
|.100" to .999" (2.54mm to 25.37mm)||+/-.025" (.635mm)|
|Over 1.00" (25.4mm)||+/-.040" (1.01mm)|
|Up to .001" (.025mm)||±.0002" (.005mm)|
|.001" (.025mm) to .002" (.050mm)||±.0003 (.0076mm)|
|>.002" (.050mm) to .010" (.254mm)||±.0005" (.0127mm)|
|>.010" (.254mm) to .020" (.508mm)||±.0010" (.0254mm)|
|> .020" (.508mm) to .050" (1.27mm)||±.0025" (.0635mm)|
The shelf life of solder preforms is dependent on the alloy composition. Pb-free alloys, and alloys with lead content of less than 70%, have a shelf life of one year from the date of manufacture (DOM). Alloys with lead content >70% have a shelf life of six months from the DOM.
For applications requiring material wider than 3", we make solder foil sheets in sizes up to 144 square inches. We also can custom-cut sheets in larger sizes or special shapes.
Standard tolerances on foil dimensions are +/-.062" (1.57mm) on the width and the length and +/- .001" (.025mm) on the thickness.
Whether you require pure metal such as indium, tin, gold, lead, etc. or an alloy, we can accomodate your needs. Indium Corporation has over 200 standard pure metals and alloys available, or we can design an alloy just for you. In addition, our standard alloy list includes a large selection of lead-free alloys.
Several of our more popular alloys are listed below. If you need a full listing of our standard alloys, please call us and request our Solder Alloy Directory, or click here.

Store Solder Ribbon and Foil in the original container, closed securely, in 55%RH or less and at temperatures less than 22°C. It can also be stored in an inert atmosphere, such as a nitrogen dry box.
We have developed standard packaging for various alloys and ribbon widths. However, if you have specialized needs such as spool size, quantity per spool, or other requirements, we can meet your unique specifications.
Each order can be shipped with a Certificate of Analysis which includes information on metallic impurities. We can also provide a Certificate of Conformance when Solder Ribbon and Foil is made to customer specifications.
