One a busy period N542 & N12 fails and block mainline causing disruption no full train for the whole day! Sun was wet and cold couldn’t more worst timed!
TB 26-10 Printed Circuit Board Assembly Chip Resistor Body Cracking
For more information, contact Joel W. Sills, Langley Research Center, joel.w.sills@nasa.gov. Download PDF here Chip resistors are widely used in NASA projects, yet cases of alumina substrate cracking during environmental testing are rare. Two instances of thick-film chip resistor cracking were observed during thermal cycling after vibration, with fractures occurring across the short axis due […]
