I recently designed and ordered some 4-layer PCBs for a quite complex commercial mixed signal project. This was my first 4-layer design for 10 years, my previous experience in Eagle was not good and I found this time using EasyEDA it was a much easier experience and the PCB that was manufactured was perfect. I did a second design replacing several chips to reduce the BOM and again the experience was easy and again the PCB worked first time. It may be just luck or it may be a case of how easy the software is to design with Anyway I am so happy and needed to share the experience Keep up the great work! ![4-layer board][1] [1]: /editor/20170224/58af683dd73e8.png
