MPPE/SEBS Composites with Low Dielectric Loss for High-Frequency Copper Clad Laminates Applications

Copper clad laminates (CCLs) with low dissipation factor (Df) are urgently needed in the fields of high-frequency communications devices. A novel resin matrix of modified poly (2,6-dimethyl-1,4- phenylene ether) (MPPE) and styrene-ethylene/butylene-styrene (SEBS) was employed in the fabrication of high-frequency copper clad laminates (CCLs). The composites were reinforced by E-glass fabrics, which were modified with phenyltriethoxysilane (PhTES). The composite laminates obtained exhibited impressive dielectric loss of 0.0027 at 10 GHz when the weight ratio of MPPE to SEBS was 5:1.

Understanding Circuit Material Performance Concerns for PCBs at Millimeter-Wave Frequencies

Millimeter-wave (mmWave) frequency applications are becoming more common. There are applications utilizing PCB technology at 60 GHz, 77 GHz and many other mmWave frequencies. When designing a PCB for mmWave frequency, the properties of the circuit materials need to be considered since they can be critical to the success of the application. Understanding the properties of circuit materials at these frequencies is very important. This paper will give an overview of which circuit material properties are ...

Screen Printer Help - 100MV UP100 or Quad 100MV -- I'm new to this forum. I recently purchased a 100MV Screen printer and unfortunately; it arrived damaged. I was able to turn the unit on and I was able to get the unit do the initiation process (ex. datums). When I tried to do a sample PRINT operation; then a vacuum menu window showed and immediately the LCD became non-responsive. I restarted the unit and still non responsive. I tried removing the IC of the LCD and the main board and re-installing it; and still no response. Any help will be appreciated.
