EEVblog #861 - Rigol DP832 PSU FAIL & REPAIR
Dave repairs his Rigol DP832 Lab Power Supply.
Why did it need repairing? That's the FAIL part Rigol might want to look into...
UPDATE: I have an old revision board. Newer ones contain a much beefier MOSFET:

Dave looks at some issues with fanning out tiny 0.4mm pitch BGA packages, via pad and hole size, tenting, breakouts, solder mask expansion etc.
And then compares it with an 1136 pin Xilinx Virtex 5 FPGA with 1mm pitch to show the difference in PCB process technologies needed.
