Solder Spheres suit BGA and CSP components assembly.

Press Release Summary:



Ultra-Spheres® support optimized ball-attach applications of ball grid array (BGA) and chip scale package (CSP) components. They resist surface darkening induced by transit tumbling and ball placement equipment. Product is available in solder alloys such as eutectic tin/lead and high lead (typical for ceramic BGA packages), as well as lead-free solder alloys. Sphere diameters are available from 0.012-0.035 in.

Northrop Grumman Introduces Innovative Solder Spheres for BGA and CSP Components Assembly



DES PLAINES, Ill., - July 31, 2003 - Northrop Grumman Corporation (NYSE: NOC) announces that Kester®, a business unit of the company's Component Technologies sector, has introduced Ultra-Spheres®. The solder spheres support optimized ball-attach applications of ball grid array (BGA) and chip scale package (CSP) components.

Ultra-Spheres® are engineered to resist surface darkening induced by transit tumbling as well as ball placement equipment. This surface-darkening resistance eliminates vision systems' false "missing ball" error readings that may result in the unnecessary scrapping or rework of acceptable product.

Kester's Ultra-Sphere® distribution exceeds industry expectations and eliminates unwanted sphere sizes (undersized or oversized), and they support high-yielding ballattach processes. To ensure homogeneity of the solder alloy, Kester® combines the use of only the highest quality virgin metal with award-winning quality practices for a precisely controlled alloying process.

Ultra-Spheres® are available in many solder alloys, including eutectic tin/lead and high lead typical for ceramic BGA packages as well as many of the industry demanded lead-free solder alloys. A wide range of sphere diameters for BGA and CSP ball attach applications are available from 0.012 to 0.035 inch (0.3 to 0.889 millimeter).
