The likely cause of your boards not working is overheat. The heatsinks used on the top of the ASICS are not adequate to dissipate the required 30 percent.

Electronics solder melts around 185 C (365 F), correct?

No, 217C for lead free. Leaded is lower as suggested but the AMT boards are lead free. This is during the assembly process. The ASICS need to be kept well below the 100C rating for them to be happy when power is applied and they are running. The ASICS burn up almost immediately when not heatsinked properly. Once one goes, the whole board is down because the A1s are daisychained.
