| We're getting field failures in a high impedance portion of the circuit. Think the unpopulated pc card has contaminates because we were able to grow dendrites by applying a 9 volt battery across the suspected pad, placed a drop of de-ionized water

| We are having a process related problem with pullup resistors on a controller card which has a I960 micro-processor. | The controller monitors signal inputs and it's own resources then blinks a LED to indicate its working. The problem is that after

�Another direct measurement to determine resistivity values (i.e. of remaining no-clean residues) can be performed through impedance spectroscopy. The surface resistance underneath chip resistors and capacitors can be determined to show the improveme

Hi John, They may still read the correct value initially, but they are not going to age well if the electrodes start oxidising. Also the high voltage surge performance & the impedance are likely to be effected, however these may be unimportant to y

Do you design or define PCB layouts? If so circuit board, what rules and checks do you have in place to make sure your results are... optimal? Over the years, I've created a PCB design checklist to keep me out of trouble. I share these nuggets with m
