Visitors to the IPC Midwest Conference & Exhibition (August 22-23) will have the opportunity to learn more about circuit-board materials, courtesy of a quick visit to Rogers Corp. at booth  No. 503. The firm is promoting its Theta® circuit materials, suitable for both high-frequency analog and high-speed digital applications. Those seeking continuing education can also attend a presentation by Rogers Corp.’s noted blogger and presenter John Coonrod, who will be giving a talk entitled: “New Developments in PCB Laminates, Halogen Free and Lead-Free Soldering Capable.” His chat is scheduled for August 23 at 10:15 AM. And for those who can’t make it to the show, they can still download the new ROG Calculator App for free. It can perform measurement conversions, calculate required copper thickness for different applications, estimate the coefficient of thermal expansion (CTE) for different materials, and several other useful materials-related calculator functions.
