Somers Thin Strip

Going Above and Beyond

Since 1909, Somers Thin Strip has excelled in developing the manufacturing expertise to produce exceptionally thin metal strip products. This proficiency, combined with an unwavering commitment to research and innovation, has established us as the world leader in the production of customized thin gauge metal strip.

Today, we ship wrought foil products with thicknesses of 10 microns and peelable foils of 1 micron. In addition, we offer a variety of value added surface enhancements and coatings, including our signature CopperBond® treated foils and CopperBond® XTF Xtra Thin foils.

At Somers, our guiding philosophy has always been to work closely with each customer to meet their specific application needs. And that, we believe, is the ultimate reason for our longstanding success. Because the material solutions we develop are the direct result of addressing challenges that arise in the markets we serve. Your markets. Your challenges. Your solutions. That’s Somers Thin Strip.

Precision Metal Foils Tailored To Your Needs

Somers Thin Strip produces specialty metal foils whose precision and performance are unsurpassed in the industry. Our product line, which includes stainless steel foils and a number of distinct precision copper foils, is outlined below.

Stainless Steel

Somers Thin Strip produces extremely flat, thin and wide stainless steel material to the tightest tolerances necessary for the most stringent applications in a wide variety of markets. Reader head suspensions, photo etch components, deep drawn components, and solar panel substrates – that’s just a sampling of the extremely demanding stainless steel products we support.

Roller Copper Foil (RA Copper Foil)

Thin rolled copper foils (known as RA Copper Foils in the printed circuit industry) are a mainstay of Somers’ precision copper foil product line. Using a combination of rolling, annealing, leveling, slitting and finishing, we produce specialty copper alloys custom-made to specific customer applications, including printed circuits, electromagnetic shielding and rechargeable batteries.

Copperbond Treated Copper Foil

Rapid growth in the flexible printed circuit and battery industries has fueled parallel advances in our own technology, resulting in our development of proprietary surface treatments and enhancements for increasingly specialized applications, including:

One example is our CopperBond® dendritic surface treatment, which provides a tightly adhering, uniform, electrochemical deposition of copper or copper-nickel dendrites on the foil surface. It offers significantly greater bond strength over that of smooth copper, due to a tightly controlled, irregular topography that causes a uniquely effective “hooking action” to occur between the copper, adhesive, and substrate.

Multiple types of surface treatment are available on the rolled foils, including CopperBond® Pink treatment, CopperBond DT™ (double-side-treatment), CopperBond Black™ (a low profile copper-nickel treatment), as well as nickel-plating.

Additionally, increased miniaturization and performance demands have also driven Somers to introduce copper alloy foils with higher strengths and different properties than pure copper foils, rolled to thicknesses from 0.00039” (10 µm) to .016″ (400 µm), with or without surface treatment.

XTF

As electronics products become smaller, faster and more complex, the demand for high-density interconnect (HDI) printed circuit boards continues to rise. CopperBond® XTF was developed to give forward-thinking designers the tools necessary to use HDI technology to its full capacity.

CopperBond® XTF is an extra-thin releasable (peelable) foil on a thicker carrier foil, with customized thickness ranging from 1 to 5 microns to meet your applications requirements. The extra thin ED Foil is carried by a releasable 1-ounce (35 micron) copper foil, which utilizes an inorganic release layer to provide exceptionally consistent release force even when laminated at elevated temperatures.

The result? A product that is being embraced as “the next generation of thin” by the engineers who are taking electronic components into ever smaller, faster territory. A breakthrough for the industry. Business as usual for Somers Thin Strip.
