Custom-made surface-mount and insert-mount lead frames from Photofabrication Engineering (PEI) are flexible, strong, burr-free and stress-free. Single- and double-sided lead frames that are too complex to be manufactured by traditional metal stamping methods can be fabricated quickly and easily using photochemical machining. Milford, MA (PRWEB) May 21, 2013 Photofabrication Engineering (PEI) manufactures a complete line of custom, photochemically-etched surface-mount and insert-mount lead...

redOrbit Staff & Wire Reports - Your Universe Online Researchers at one US university have developed a new, low-cost method of etching minute features onto semiconductor wafers while monitoring the process as it happens. University of Illinois electrical and computer engineering professor Gabriel Popescu and colleagues say that their method allows chipmakers to use a special microscope that uses two beams of light to precisely measure the topography. Their technique allows...

Gallium nitride (GaN) is a highly promising material for a wide range of optical and high-power electronic devices, which can be fabricated by dry etching with plasmas. However, the plasma-induced defects and surface residues that remain after such processes tend to degrade the optical and electrical properties of the devices. A team of Japanese researchers has developed and tested a new way to "heal" such defects. The team exposed plasma-damaged GaN to hydrogen (H) radicals at room...
