content: I have just got my paws on another PCB thermal analysis camera for use on workbenches in the repair of things like mobile phones and laptop PCB's. The advantages of having a thermal imaging capability when diagnosing some faults on modern PCB's has driven the development of bench top thermal camera solutions over the past few years and there are a few models to choose from. Early models were constrained by the availability of affordable, decent quality, imaging cores with useful optical resolution for the tiny SMT components used on modern PCB's. With the arrival of the Chinese produced 256x192 pixel Tiny1 and TIMO256 cores the situation changed for the better and new models of PCB thermal analyzer appeared and provided excellent capabilities.Qianli is a Chinese company that specialises in mobile phone repair tools and they include thermal imaging systems in their tools range. They have offered different PCB thermal analyzers over the years but their primary model now is the "Supercam X". Qianli does not make their own thermal imaging equipment and relies upon another company for design and production. I know that OEM thermal imaging company well and they do produce some nice designs that use excellent quality components. With this in mind I was interested to see a Qianli PCB thermal analyzer kit for sale on eBay that I had not seen before. It is called the Qianli Fire Eye Pro PCB thermal analyzer and comprises a manual focus (2mm to Infinity) thermal imaging dongle and a metal bench mount to hold the dongle above a PCB. The camera to PCB distance is adjustable but it is not a conventional microscope mechanism as such is not truly needed with a manual focus camera lens system. I had seen the fixed focus Qianli Fire Eye camera dongle that resembles many other thermal dongles such as the Infiray P2 eta al. I had not seen a manual focus version of this camera though. Having just tested the DYT designed and build CA-09B that uses a fixed focus lens camera, I am of the opinion that manual focus is very desirable in a bench mounted PCB thermal analysis camera. The Fire Eye Pro has a very neat folding bench mout to make it very portable for mobile use. A little digging into the internet provided the details I required to buy the Qianli Fire Eye Pro system for some testing and, hopefully, use in my lab.What surprised me when searching for information on the Fire Eye Pro was the lack of a brochure or manual for download. Even more surprising is the fact that Qianli list only the "Supercam X" on their web site and the Wayback machine did not show the Fire Eye Pro to have ever been present on the Qianli web site. That seems strange as the camera system is still available to buy under the Qianli brand and was released in 2024. I have no explanation for this situation. There are plenty of China based sellers offering the Fire Eye Pro system via AliExpress and some are well known, such as PhoneFix.Once the Fire Eye Pro arrives, I will test its performance and report my findings here in case it helps forum members decide between a manual focus and fixed focus PCB thermal analysis system. Having both the DYT fixed focus CA-09B and the manual focus Fire Eye Pro gives us a good comparison of capabilities as they share the same resolution and possibly the same core technology.I am currently using and testing the Thermal Master THOR-002 so no time for other testing at the moment, but I will get around to this unit in due course.

content: The Qianli Fire Eye Pro kit arrived a few days ago and I have just got around to testing the camera dongle.Ever wondered what an Infiray P2 would be like with a manual focus lens ? If so, the Qianli Fire Eye Pro is that camera !I was using the Fire Eye Pro dongle on my mobile phone with the Infiray P2 Pro app that I already had on there. All seemed to work OK. The manual focus is very fine threaded for easy of use and the lens barrel is metal. Very nice quality. The only issue with the manual focus lens is its size. The lens barrel and focus ring is so small that my fingers are visible whilst adjusting focus. I am already thinking of designs for a larger diameter focus ring that I can push on to the metal focus ring to move my fingers away from the field of view. Not a difficult problem to solveI think I am going to like this Qianli Fire Eye Pro and it’s very nice metal bench standFraser

content: Some pictures of the Qianli Fire Eye Pro camera dongle alongside the Thermal Master P2 and Infiray P2 Pro dongles for size comparison.As can be clearly seen, the Infiray remains the "baby" of the line-up with its amazingly small size. The Qianli Fire Eye Pro is the largest of the three but I can forgive that as it is a solid design intended for both mobile phone and bench use on a stand. For me, the inclusion of a manual focus lens on the Qianli product compensates for its larger size. The stated focus range of 2mm to infinity is impressiveThe fact that my P2 Pro software works with it is also a bonus. It remains a mystery to me why we have not seen more of this camera dongle under the Qianli or another brand name.Fraser

content: For lenses too small for my fat fingers i just wrap a cabletie around and use the tail as an adjustment lever.

content: An excellent “modification” 👍I was thinking of fitting a large rubber grommet around the focus ring to make it a larger diameter but there is not much width to the focus ring so that approach might not work. A small cable tie would fit though.Fraser
