WebTheir low height of 0.134 (3.4mm), for the 3A and 4A converters, and 0.173 (4.4mm), for the 6A converter, makes them particularly suitable for high density racks, blade systems, … Web18 de mai. de 2024 · It can be seen that: (a) at 2 GHz, the Dk = 3 and Df = 0.0025, (b) the CTE = 25 × 10 −6 /°C, (c) the tensile strength = 630 MPa, and (d) the tensile strength on the Cu rough side (Ra = 1.8 μm) is 7 N/cm and on the Cu shiny side (Ra = 0.25 μm) is 5.5 N/cm. All these values are better than expected. Fig. 10.2 Web1 de out. de 2024 · At first we have re-designed the polymer backbone in order to obtain low Dk and Df performance. As a result, our new non photosensitive PI achieved 2.9 of Dk at 20 GHz and 0.003 of Df at 20 GHz. In the next step, we selected the photo package of new PI carefully to maintain both low Dk/Df and high resolution. iphone pro max manual
