![]() This is one aspect in which the Flir One Pro thermal camera does great because the two sensors are perfectly aligned. Now the problem with this is that you have to have the two cameras close to each other, so the best thing to do would be to connect it to your smartphone and then output the image via screen mirroring or USB cable to a larger screen, or if you are using a tablet you should buy an extender cable and mount the thermal camera as close as you can to the visual camera for electronic testing, so they have pretty much the same angle on the motherboard or electronic circuit board which you are trying to diagnose. This can be a very powerful camera thermal camera for PCB inspection and PCB diagnosis, once you have it set up properly. The two images are superimposed in the app so you can have the thermal reading and you can read the exact details on the chips and components like part numbers and symbols when you are diagnosing, something which you can’t do if you only have a thermal camera. So what does this infrared thermal imaging system have that makes it suitable? It is a combination of a high 320 x 240 infrared resolution and the ability to use your smartphone’s or tablet’s visual camera in the app. Like the HT-301, we recommend mounting this on a tablet and this time you also have the option of connecting it to an iPad because it comes with either a USB-C, micro USB or a Lightning connector. The Seek Thermal Compact Pro is also a smartphone thermal camera that is great for PCB boards an any kind of electrical circuit board. Out of all the industry thermal cameras for Android, this is going to provide you with the highest resolution including spatial resolution and the highest frame rate. This is one of the essential tools in PCB development to quickly identify and troubleshoot issues. Even better, if you use an extension cable, you can place it on top of the test bench looking down on the board and place the tablet vertically like a monitor. The best way to use this is to hook it up to an Android tablet and the reason why is obvious: You need to have a larger screen to get a clear view at all of the small chips, connectors and switches. It also has a 0.06☌ thermal sensitivity, so you’ll be able to spot even the slightest differences. This can cover any temperature up to the solder melting point and that won’t be the case. ![]() This is a professional thermal imaging camera for smartphones and its temperature range is also suitable because it can accurately measure any object which has a temperature between -4☏ to 752☏ (-20 ☌ to +400 ☌). It has a thermal resolution of 384 x 288 with a total of 110,592 pixels which is more than what any thermal camera under 1000$ can offer. You see, inspecting PCB boards is an activity which requires a high level of detail in the image because the components are much smaller than what you would be measuring in an HVAC inspection or plumbing. The main reason for why we included the Hti HT-301 in our list of thermal cameras for electrical circuit boards and PCB manufacturing is because of its very high IR resolution.
