I have used infrared imaging to find electrical shorts on logic boards between the 5 Volt buss and ground. You can power the electrical short up to draw 50 to 100 mA and then look for the warm spot in the infrared display.

Is it safe to use the 100M ohm value found in Table 2 of J-STD-004 as a minimum for SIR with respect to flux specification acceptability? It (J4) appears to imply that that value provides some level of acceptability, but it just doesn't come right o
