Solder Ribbon and Foil
Introduction
JAYTEE Solder Ribbon and Foil manufacturing is available in many standard alloys (Leaded /Lead Free) and sizes. Material can also be made as per customer requirements.
Solder Ribbon Foil is supplied in continuous lengths and is packaged on spools or maybe in cut pieces or sheet forms.
Ribbon Dimensions
JAYTEE has capabilities to manufacture widths as small as .020" (.5mm) and up to 2.25" (57.15mm). Thicknesses range from .001" (.025mm) up to as thick as your application requires.
We can work with you on your specific dimensional requirements. Our typical tolerances are:

| >.010" (.254mm) to .020" (.508mm) | ±.0010" (.0254mm) |
| >.020" (.508mm) to .050" (1.27mm) | ±.0025" (.0635mm) |
| >.050" (1.27mm) | ±5% |
Shelf Life
The shelf life of solder Ribbon / Foil is dependent on the alloy composition. Pb-free alloys, and alloys with lead content of <50%, have a shelf life of 1 year from the date of manufacture (DOM). . lead content>50% have a shelf life of 6 months from the DOM.
Foil Dimensions
For applications requiring material wider than 3", we make solder foil sheets as per customer requirement. We also can custom-cut sheets in larger sizes.
Standard tolerances on foil dimensions will be applicable.
Available Materials
You can choose the solder Alloys grade as per your specific requirement from the Table 2. Which listed on the book of this data sheet.
Storage
Store Solder Ribbon and Foil in the Tightly closed container in standard room temperature. It can also be stored in an inert atmosphere, such as a nitrogen dry box.
Packaging
We have developed standard packaging based on alloys compositions and ribbon widths or as per customer specific requirements.
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.
