CLTE-MW™ Laminates

CLTE-MW laminates are ceramic filled, woven glass reinforced PTFE composites. These 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 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/ºC) 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.
