"Shotgunning" a Bad Fit for Lead-Free Test

Application Notes

Among all test and inspection techniques, functional test has the lowest diagnostic resolution, which has given rise to a common repair technique known as shotgunning.

In shotgunning, a repair technician suspects that a particular component is faulty, replaces it, then discovers that the problem has not been solved. At that point another suspect component is replaced, followed by another and another. This process continues until the board is repaired, or it is damaged beyond repair, or a preset number of repair attempts is reached, or the technician runs out of ideas and sends the failing board to the scrap pile.
