Chandler, Arizona -- Rogers Corporation (NYSE: ROG) will be showing off some of its latest PCB materials as well as a free design program at this year’s DesignCon 2011 exhibition (Santa Clara Convention Center, Santa Clara, CA, February 1-2, 2011).
Rogers will be presenting its Theta materials, a next-generation halogen-free laminate that addresses market needs for a lead-free assembly compatible, CAF-resistant material ideal for high-speed digital circuits. The company says that leading PCB fabricators and OEMs have evaluated Theta laminates in some of the industry’s most challenging high-layer-count designs, and that it has surpassed expectations by meeting both 260°C 10X lead-free assembly conditions and successfully withstanding 0.8-mm CAF pitch conditions.

Theta materials feature a low z-axis coefficient of thermal expansion (CTE) of 50 ppm/°C -- about 30% lower than FR-4 for reliable plated through holes (PTHs) in multilayer designs.
Also on tap at the show, the company's MWI-2010 Microwave Impedance Calculator program is available for free download from the Rogers website at www.rogerscorp.com/acm. Supplied as an executable file that will run on any Windows-compatible PC, the MWI-2010 software provides quick, easy calculations of key transmission-line parameters based on the use of Rogers’ extensive lines of high frequency circuit materials.
Using proven closed-form equations, the program can calculate the impedance of high frequency conductors based on a variety of transmission-line technologies, including microstrip and stripline, and laminate materials. The straightforward utility provides simple on-screen menus to guide users in their selections of transmission-line technology, material, material thickness, conductor thickness, and other parameters. Menus list materials as well as their relative dielectric constants, dissipation (loss) factors, thermal conductivity, and thermal coefficient of dielectric constant.
DesignCon (www.designcon.com/2011), the first major electronics industry event of the year, is a key forum for specifiers of PCB materials, semiconductor devices and ICs, modeling tools, and test equipment. The Rogers team at booth No. 711 will be on hand to offer advice on the use of the halogen-free Theta materials and for the free MWI-2010 Microwave Impedance Calculator software.
