Isola helps designers achieve smaller, more powerful and durable and less power-hungry products.

Today’s RF, microwave and millimeter wave designers are challenged more than ever with the task of achieving an optimal balance between cost and performance when selecting base materials. Key factors include precise control of dielectric thickness, dielectric constant and dissipation factor, achieving lowest tolerance within a batch as well as batch-to-batch. To achieve controlled impedance and consistent electrical performance, along the lines of amplitude and phase response, RF high-frequency designs require extremely precise controls on dielectric constant, line widths and dielectric thickness. If any one of these three factors is changed, variations will be seen in the performance of the circuit. As frequencies increase, designers are looking to controlled dielectric materials as a means of achieving optimal signal performance. This would include the designers also paying closer attention to the selection of copper foils such as VLP-2 (very low profile 2 micron), as well as woven glass styles such as square weave or spread glass styles that would also help improve overall performance and ease of PCB manufacturing.
