Manufactures a Line of Photochemically-etched Electrical Contacts 

SG-etch manufactures a line of photochemically-etched electrical contacts made of beryllium copper for integrated circuit manufacturing. The beryllium copper contacts are ideal for products requireing exceptional hardness, strength, self-lubrication, and good thermal and electrical conductivity.  They are highly beneficial in spring applications that result in high usage or high stress to the parts. 

SG-etch manufactured contacts are used in a wide variety of applications, including printed circuit board connectors, appliances and lead frames for the medical and electrical/electronic industries.  SG-etch also provides electrical contacts in other materials including copper and brass, with tin, nickel and nickel-gold plating.

SG-etch will design lids to exact customer dimensions and specifications to ensure a precise fit on customer packages, and will guarantee the proper fit.  For 0.010 in. (0.254 mm) to 0.015 in. (0.381 mm) lids, the typical tolerance is /- 0.003 in. (0.076 mm) on features and /- 0.001 in (0.025 mm) on the flange.  Flatness will be held to 0.002 in (0.05 mm) per inch (25.4 mm).  On lids 0.020 in. (0.5 mm) or greater, typical tolerances vary due to material thickness.  Whatever your tolerance requirements, SG can meet them -- contact our etching sales department for details at sales@sg-etch.com.
