Nice! Couple of other interesting effects and uses: - "Mirror" - if you have a sheet of copper, or a bare copper-clad PCB, you can use this as a "mirror" to look around corners, or even look at yourself - "Tape" - most tapes, even 'transparent' polyimide tapes are opaque at IR and can be used to create an emissive patch on a metallic surface - "Transients" and "front-propagation" - If your IR camera has a "video recording" feature, you can do useful stuff, like pumping cold (or hot) water into a cooling-block and see how much and how rapidly and in what direction the temperature changes. Problems like clogged water-manifolds, debris on the inside of the pipes, etc. can be easily observed. - Seeing where your cat/pet has been sitting while you were away :) Even fingerprints and butt-prints are observable after minutes. I am thinking of buying an inexpensive unit for home use. Should I go for - One with a slightly higher resolution than this one? - One with an adjustable lens? (or is an external ZnSe lens better?) - A smartphone/USB-C add-on instead of a full "pistol"? thanks!
Well, in my experience (I have a Flir One), the add-on type camera has quite a small battery, so it will need very frequent recharges; also its not always compatible with every single smartphone. Adjustable lens cameras will probably not be cheap; a ZnSe lens can be bought for ~30$ if you really need to zoom into things. Otherwise, for low resolutions focus isn't that important. Resolution, is price dependent - the higher your budget is, the higher resolution you should pick. I would also suggest that whatever camera you decide to buy, first check the post-processing software. I find it invaluable to edit IR photos after they have been taken.
What an informative video! Like your video so much! I usually use Infiray P2 Pro thermal camera to observe the 0201 resister. Circuit repairer should know that the size of the resistors is only 0.5mm×0.25mm, but P2 Pro has magnetic macro lens that provides high-quality thermal images. It's in one word, amazing!
Nice video! I have used IR cameras a lot on troubleshooting as well. A faulty (or shorted) IC for example will lit up most of the time. Which is extremely easy to spot on an IR image.
I know the old way of doing this was using the finger temperature meter, but that can be quite painful, on the one hand if the component is very hot, on the other if the circuit uses high voltages; so the IR method is far more accurate and safe.
Excellent video. Yesterday I splashed out on an Hti-Xintai HT-102 320x240 IR plug-in camera for my Android phone, 20% off on an Amazon Black Friday deal. Works well and seems pretty accurate on temperature checking against my RS-Pro dual thermocouple meter. Main purpose is to hunt down faulty components during repair work when using voltage injection. Sadly the first board I tried it on had a short on the main 3.3v rail and the fault was a dead Xilink gate array for which I don't have the programming so that's a no fix 😟
It is also useful with contact probes when the electronics is inside of an enclosure. Removing the enclosure will lead to better cooled electronics so removing the enclosure for being able to use the camera will give the wrong picture of the temperature.
Awesome stuff for the price, especially the software which comes with it! Would be interesting to check the accuracy (in terms of temp values) of the heat map on 10:58 with the thermocouple or RTD.
I do plan to upgrade my temperature measurement setup in the future, I might revisit this experiment then - to measure multiple points accurately on a small surface with contact sensors.
very nice touch with the macro lens. you said the sensor in that camera is not cooled? that's very interesting since I've been used with IR cameras that either need liquid nitrogen or they have a peltier cell, both used to provide a cold reference temperature to the sensor.
@@domtom128 Indeed, this is a microbolometer type of sensor - its less expensive and thus does not need cooling; I guess it has an on chip thermistor so it always knows its reference temperature.
Thank you for the nice video and I may buy this IR camera. I need it only for PC boards so that ZnSe Focus lens would be a very important addition. I did check eBay as you suggested to another poster. I would appreciate it if you could supply a little more information on the lens. There are many with different diameters some vary in focal length and of course prices form $7 and way up. Looks like you made a 3D printed holder and I have a printer so the lens fixture would be easy to make. Thanks for any info you can supply.
Hello! The particular lens I have chosen has 20mm diameter and focal distance 50.8mm, and its the "ZnSe" type, not CVD something something; Realistically you could go with 10mm diameter, but you need space for the holder, to hold the lens, so part of the lens will not be usable - that is why I went with 20. Focal length - it should represent what the distance from which the object is in focus, I do need to check this though. I chose 50mm so the lens has a bit of clearance to the circuit.
@@FesZElectronics Thank you for the fast reply. I found a lens with the specs you recommended and ordered it from eBay. I also ordered the IR Camera B1L from Amazon with Cyber Monday pricing. The IR camera should be here in two days. Again thank you for your help in this purchase!

For motherboard of computer
Different components and parts of the board will have different values... there is no fixed value to use for an accurate measurement
