CLTE Series™ Materials

CLTE series products are woven-glass/PTFE/microdispersed ceramic composite laminates. CLTE Series materials offer stable electrical performance over temperature, critical for phase sensitive applications. Woven glass matrix provides excellent dimensional stability; ideal for thin core, multi-layer boards; highest degree of embedded resistor consistency in the industry. Low CTE values ideal for high reliability plated through holes for Avionics, Radars, EW, SIGINT, CNI (Communications, Navigation, Identification), and Phase Sensitive Filters.
