Raspberry Pi 3 Model B running Raspien in idle state

During testing the various larger IC's were seen to having changing thermal output and one in particular was pulsing hotter and cooler. A video of this effect is included at the end of the test pictures.

Amazon Firestick TV Dongle Mk1

These particular TV Dongles are well known fro running rather too hot for their own good. There are blue heat pads thermally coupling some areas and IC's to the casing but as the casing is plastic, metal has had to be added in one area to aid cooling. The coling remains inadequate however and a metal casing woul dbe neeeded to significantly imptrove this aspect of the desigm Look at the temperatures on teh IC's after only a short period of being powered and not even actively streaming data.

A couple of videos of the firestick showing one IC pulsing in standby and another showing internal activity that is cyclic with different areas of the IC 'lighting up'

First the pulsing IC

Now the video of activity inside an IC. You will see a hotter area at the botton left of the IC, then two areas at the top becoming active and then a 'flash' of energy as the left around to teh top top of the IC caused by an increased thermal output for just an instant before dropping back to the hotter botton left area. The 25fps frame rate really helps to capture such events

Conclusion:

The CA-10 system provided good performance in keeping with the claimed specification and capable of good real time analytical work on PCBA's for the purposes of R&D or Repair.

The CA-10 PCBA Analysis thermal camera was originally conceived as a thermal imaging tool for the buoyant Mobile Phone Repair Industry. Real time thermal analysis was the overriding requirement, rather than 'offline' deeper thermal analysis as might be found in a Research and Development environment. Dianyang Technology recognises the potential use of the CA10 for Repair and R&D activities and has included features in the analysis software package that are useful in both applications. The absence of Radiometric file saving is a pity but not a showstopper in the authors opinion.

As Dianyang Technology continue to develop their DYTSpectrumOwl software package, we may see additional functionality added to provide greater support for more advanced R&D activities. As it stands, the CA-10 offers an excellent real time PCBA thermal analysis capability with both versatility and accuracy being demonstrated in the testing.

But this is not the end !

I will be adding a Technical Annex to this review for those who desire such information on this product.

I will also be adding thermal analysis pictures from more electronic equipment as I get around to testing it with the CA-10

This thread will be updated with further posts regarding the CA-10 and its imaging capabilities as and when possible.

I will also be making comment on where the CA-10 DYTSpectrumOwl software may be enhanced to make the CA-10 and even more powerful thermal imaging tool for R&D work. As already ststed, the CA-10 was designed for simple use in real time to repair electronics rather than use in complex R&D tasking. The software dictates much of what teh CA-10 is and can do so Dianyang Technology may decide to enhance the software for more advanced tasking of teh demand is present in the marketplace.

Please feel free to make comments and suggestions now that I have posted thos review as I feel sure Dianyng technology will read this thread and note comments made on their product.

My thanks to Dianyang technology for supplying the CA-10 review sample.

Technical Annex:

Annex A:

Technical Description

The CA-10 uses a self contained thermal imaging core with USB output to a PC Host that is    running proprietary software. Power is supplied    from the USB cable and controlled via a custom DYT power control    PCB in the camera head. The software application running on the Host PC controls the camera core and processes the thermal data coming from it.

The imaging core detail researched by the Author but not confirmed by Dianyang Technology. E&OE

The Imaging Core Specifications

   Imaging Core - A domestic Chinese core of advanced design.
   Pixel Type : 12um VOx Microbolometer with a 'thermal enhancer' on top of each pixel
   True Resolution : 256 x 192 Pixels
   Frame Rate : 25fps
   NETD: <60mK with f1.0 lens
   Lens Field Of View : 42 x 32 Degrees
   Flat Field Correction : Solenoid operated FFC shutter
   Measurement Range: -20C to +120C with potential for higher temperatures.
   Measurement accuracy : Better than +/-3C or +/-3%
   Image enhancement: Multi Level DDE
   Environmental operating temperature range: -15C to +60C (for Core)

Annex B:

The Camera Head

The camera head of the CA-10 contains a miniature thermal imaging core that communicates with the Host PC via USB.
Power for the imaging core is supplied by the USB link and managed by a custom Dianyang power control PCB.

The cameras manual focus lens is extended out to a manual focussing ring for user operation. The manual focus ring is a two part design with the rear section mounting around the cores lens barrel. This is secured in place using three grub scres at 120 degree spacing. The front section of the focus ring is attached to the rear section with two machine screws and centralised through teh use of shaped mating flanges. The Lens barrel and focus ring components are made from anodised aluminium and are of good quality.

I attach some pictures of the camera head design.
