8 years ago --- Quote Start --- Target MAX10: 10M02DCV36I7G [*]Single 3.3V supply power : VCCIO3_5_6 = VCCIO_1_2_8 = VCCA = VCC_ONE and are all connected to a single 3.3V LDO regulator --- Quote End --- 10M02DCV36I7G is not a single supply device - and as your schematic shows, there is no VCC_ONE because this part needs separate supplies for core (1.2V) analogue (2.5V) and I/O (could be the same as one of the other supplies, but you appear to need 3V3). I don't think that the single-supply parts are available in the WLCSP36 package size. --- Quote Start --- [*]Asked the manufacturer which sort of test they performed: Their answer “all the board passed assembly optical inspection (aoi) and solder paste inspection (spi)”. So apparently it shouldn’t be a soldering issue. --- Quote End --- AOI isn't enough to prove you have no soldering faults - you'd need X-Ray inspection for that on a BGA. But probably in this case you've simply blown up the device by applying 3V3 to the core.
