Wed Apr 12 12:32:13 2023, PJCS, ASIC power short problem
|
I have taken videos with an Infrared camera of the power being supplied to one isolated ASIC on a mezzanine.
The power supply is a bench supply with current limit set to 3A.
The centre of the ASIC glowed white hot for a short time and then the whole ASIC shows as hot. Ths the short is on the ASIC and not the bond |
|
Wed Mar 1 16:42:06 2023, Further results from Mezzanine bench tests, PJCS
|
Carried out some further work on failed mezzanine modules.
Inspected them externally and removed the copper block, internally with a bench microscope.
Found two obvious faults ..... broken components with scrambled pcb tracks. |
