Low Voltage preamplifier board

modular analog input preamplifier board for mV range signals. PCB build quality is great. Some minor, insignifficant defects on 2 of the batch - scratch on ESD guard ring on one of them, and approx 0.2mm diameter hole in solder mask in another. Defects are in location where they do not cause trouble. The rest of the boards are oawsome. Internal manufacturer number is placed in nice location. During soldering none of the pads lifted 😀. board outline is nicely processed , no sharp edges..
