MCU_Board_A_v1.0.2b0

The different in quality of the assembled board, that I experienced was actually the bond of the copper trace and also solder pad to the board FR-4 material are quite strong. Many times in my experience during prototyping a board, we need to replace some components, for example resistor that we want to try several values. Then obviously we may need to desolder it. With this board, I was desoldering 0603 SMD resistor then solder a replacement resistor on same location several times, because I need to test several Ohm value. It was quite easy and I don't messed up the pad and trace near the component location. My past experience with different manufacturer was either the copper trace or the solder pad was pulled out from the FR-4 material. But it didn't happen on this case, that proving the quality of the board by pcbway is okay and quite reliable.
