The UQ20.03, manufactured by Rogers Mektron, is a rigid-flex printed circuit board (PCB) material utilizing Rogers Mektron 90+ dielectric. This laminate exhibits a high glass transition temperature (Tg) exceeding 280°C, providing enhanced thermal stability for demanding applications. The “NOT RoHS” designation indicates that this specific variant does not conform to the Restriction of Hazardous Substances Directive, implying the potential presence of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs), or polybrominated diphenyl ethers (PBDEs) above the allowable limits. Consequently, its use is restricted in certain regions and applications. The UQ20.03 designation likely denotes a specific construction or layer count within the Rogers Mektron product line, tailored for applications requiring high reliability and thermal performance where RoHS compliance is not a primary constraint. Further specifications regarding copper weight, overall thickness, and impedance characteristics require additional documentation.
