I got them from one PCB manufacturer. By these pictures, I could clearly know prepreg material and thicknesses of each layer. It seems that I can also calculate trace widths, right?</span> </p> <p style="text-align:left;white-space:normal;"> <span style="text-align:center;line-height:1.5;"></span><img src="https://file.allpcb.com/bbs/17/04/11/120027809.png" alt="" style="text-align:center;line-height:1.5;" /> </p> <p style="text-align:left;white-space:normal;"> <br /> </p> <p style="text-align:center;white-space:normal;"> <img src="https://file.allpcb.com/bbs/17/04/11/120049020.png" alt="" /> </p>
