Engineers in need of a starting point for their high-frequency printed-circuit boards (PCBs) will find them by comparing notes with members of Rogers Corporation’s Advanced Circuit Materials division at IMS booth No. 1459. Visitors to the booth will learn about Rogers’ next generation RO4000® circuit materials, notably RO4835™ high frequency laminates. RoHS-compliant RO4835 laminates offer a dielectric constant of 3.48 and a low loss tangent of 0.0037 at 10 GHz, plus a low z-axis coefficient of thermal expansion (CTE) for excellent plated-through-hole (PTH) reliability under a varietyof processing and operating conditions. These improved oxidation resistant circuit materials exhibit x- and y-axis expansion coefficients similar to those of copper, for excellent dimensional stability. Rogers Corp. will also be represented in the IMS technical program by Market Development Engineer John Coonrod, author of the “ROG Blog.” His talk, “Determining Circuit Material Dielectric Constant from Phase Measurements,” is scheduled at 3:30 PM Tuesday, June 4, in the MicroApps Theatre on the IMS exhibition floor.
