Pcb sheet information: size: 132.3*130.5MM/9PCS four-layer FR4, board thickness 1.0MM, copper thickness 10z, immersion gold, black oil white, three-level standard;
SMT welding requirements:
1 gold three fingers should be attached to high temperature glue protection
2. U5 number is easy to be misaligned, it is best to fix it with red glue.
3. If there is repair, it must be thoroughly cleaned (because the final product is bare board)
4. Pay attention to monitoring the QFN bit number, which is easier to short circuit.
Test: burn test, 1. test voltage 2. burn 3. function test
