Hi Guys. Anybody use Thermal Camera for find shortage on mobile phone board. I repair mobile phone and want to buy thermal camera FLIR tg165. Someone use this type of camera for find shortage on smd board?? is this really helpful??? I watch a video on youtube, but want to know from other technician. Thanks Update (11/11/2017) Thanks a lot Guys.. I’ll NOT BUY any Thermal camera :) :) Thanks a lot for information…..
I’m curious about this as well. However, the problem with shorts is that many times the device that delivers the current can be put into current limiting mode, which means that that the voltage goes down as well and therefore not much power is delivered…so no heat. I’d like to hear from other tech’s as well because these cameras are expensive.
While thermal imaging can be useful I don’t think it offers the detail you are expecting with such small components used in a phone. Keep in mind no all shorts will have a high current running through them. I do use a non contact thermometer to help diagnose cooling issues in laptops & desktop systems. I only work on PC’s so the phone guys will need to speak up on what they use. Here’s a Vid on someone using one to diagnose a logic board: FLIR ONE Thermal Imager Review for Electronics Debugging As you can see the image is quite fuzzy so smaller devices just won’t show up. Don’t forget you would need to have a profile already for a good working device to compare with. I just don’t think its detailed enough to be useful for small electronic devices (phones & PC’s). Here’s someone using it to locate a bad cap in a iPhone: Find Short Circuit quickly With Flir Thermal Camera - iPhone 6 no power Repair so maybe it can be useful but just watching the what he is seeing I’m not sure if I could have detected it down to the cap he is replacing. It would clearly have aimed me to a smaller area to look but not to the level of a given component. You still need to use the head and tools of the trade!
