Overall, I had a very good experience with this order. The PCB quality was clean, the solder mask and silkscreen looked good, and the pads were easy to solder during assembly. The board arrived well packaged and matched the design files I submitted. Communication during the order process was also good, especially with part review and production updates. The final board was useful for assembly and testing, and most of the circuit worked as expected after soldering. I am satisfied with the fabrication quality, assembly result, and overall service. I would consider using AIVON again for future PCB projects.
