  • How to Reduce Voiding in Components with Large Pads
    As the electronics industry moves toward. miniaturization and multifunction,. smaller components with more functions,. such as quad-flat no-leads (QFNs) and. LGAs, are increasingly used in a variety. of products. QFNs, being a near chip-scale package,. have perimeter contacts on the package. bottom
  • Covert Ops: In- and On-Product Drug Security
    at . For this reason, spectrometry and imaging manufacturers have been releasing smaller, handheld testing devices. Ultimately, testing raw materials will be key to ensuring public safety, explains Bradley. Ahura's TruScan Raman devices allow materials to be tested, as is, in the package. "Without

  • ServoClass(R) Coupling Eliminates Backlash Potential in Integrated Seam Sealing Systems; Couplings Connect Servo Motors to Ball Screws
    for the semiconductor and microelectronics industry, has recently introduced a new line of parallel Seam Sealers driven with servo motors. These systems provide linear and rotary weld sealing with real time force control and automatic package height sensing for seal uniformity. Features include
  • Automated Optical Positioning Helps Automate FT-IR Analysis
    to noise performance. In addition, the device had to be very small in order to fit within the tight confines of the microscope. Finally, it needed to operate with very low levels of force in order to avoid the need to increase the size of the power supply for the unit. Accuracy in a small package
  • Changing Face of Photodetectors
    . Discreet components are the only choice. The second level of integration is the hybrid detector, which consists of a discreet detector and a discreet signal processing chip mounted in the same package. Hybrid devices offer more flexibility and lower NRE than a monolithic photodetector. For example

    into a 40cm by 40cm space meant that motor size was almost as critical as motor specifications. Through the use of Maxon's RE 8, RE 10 and RE 13 motors, Varian was able to package 120 tungsten leaves into the limited space available. While the motors are indeed small, the truly impressive
