WebDec 5, 2010 · 2. I know how the trace burned away. I once had a newly populated PCB sitting on my workbench and hadn't noticed a few leftovers of cut off pins on the table. One caused a short between two 230V~ traces. Result when I plugged it in: trace literally evaporated over a length of 5cm and board jumping a centimeter high.

WebThe PCB burn-in process is usually done at 125ºC, with electrical excitation applied to the samples. The process is facilitated by using burn-in boards where the samples are loaded. These boards are then inserted into the burn-in oven which supplies the necessary voltages to the samples while maintaining the oven temperature at 125ºC.
