Rogers Introduces CLTE-MW Laminates for 5G and Other Millimeter Wave Applications


Reading time ( words)

Rogers Corporation has introduced CLTE-MW laminates, a line of ceramic filled, woven glass reinforced PTFE composites. CLTE-MW laminates were developed to provide a cost effective, high performance material for the circuit designer. This unique laminate system is well suited for applications that have limitations in thickness due to either physical or electrical constraints.

The seven available thickness options from 3 mils to 10 mils ensure that ideal signal to ground spacing exists for today’s 5G and other millimeter wave designs. In addition, a variety of copper foil options are available including rolled, reverse treated ED, and standard ED. Resistive foil and metal plate options are also available upon request.

CLTE-MW laminates are reinforced with spread glass, which along with a high filler loading help minimize the high frequency glass weave effects on electromagnetic wave propagation. Their woven glass reinforcement also provides excellent dimensional stability. Other key features of the laminate include low z-axis CTE (30ppm/°C) for excellent plated through hole reliability, a low loss tangent of 0.0015 at 10 GHz to enable low loss designs, and low moisture absorption of 0.03% to ensure stable performance in a range of operating environments.

Thermal conductivity of 0.42 W/(m.K) enables heat dissipation in aggressive designs along with a high dielectric strength of 630 V/mil to ensure good z-axis insulation between conductor layers. The UL94 V-0 flammability rating enables the use of CLTE-MW laminates in commercial applications.

CLTE-MW laminates are well suited for a range of applications including amplifiers, antennas, baluns, couplers and filters. Applicable markets range from commercial and consumer to defense and aerospace.

Normally, the holiday season is a slow(ish) news time, but this year just feels different. My opinion is that the technology industry banked up a whole bunch of innovations and new products during the pandemic disruptions, which are coming to market as quickly as possible. The November/December news is full of technology discussion, as my selections this week clearly demonstrate.

The industry news cycle seems to be picking up speed lately. Of course, 30 days into the quarter is about when public companies announce their results, and in the midst of this worldwide financial situation, we’ve got all eyes on anything coming out from our counterparts in the industry. I’ve noticed that global corporate results (Nan Ya PCB and TTM, in particular) do seem to be on everyone’s radar. In addition to financial news, trade shows are popping back up around the world—Europe, India, and a special report from editor Andy Shaughnessy, who took his own road trip to Raleigh, reporting on PCB Carolina, which had its own heyday this year.

I’ve been in Washington, D.C., most of this week, attending and reporting on the IPC Advanced Packaging Symposium. You’ll see more content from me in the weeks and months to come as I sort through and highlight the varied aspects of this ground-breaking event. If you’re in this industry, advanced packaging will affect you, make no mistake about it.
