Agnospcb Inspection platform 1.0 

Created to make the process of photographing the panels / PCBAs as easy as possible by providing images of the highest quality, detailed pictures and with the best illumination.


This is what Agnospcb's neural network needs to be able to perfectly detect any kind of fault present.


  • SONY Alpha  camera 

  • 50mm F1.8 Autofocus LENS 

  • 336 Leds Lighting ring (dimmable)

  • 4x Black 2020 Aluminum rails

  • Frame’s plastic parts + bolts + wingnuts

  • methacrylate base + non-reflective layer

  • Battery dummy + 2m USB cable

This platform is the perfect companion to our inspection software (free of charge for our customers), which allows to process batch/es and review in real time the images of the PCBAs taken.

Assembling the Agnospcb Inspection platform (v 1.0)

Setting everything up will take approximately 30-40 minutes

This inspection platform consists of a base and an aluminum rail which will serve as vertical axis for the lighting LED ring and camera. Depending on the size of the board you are inspecting, you might need to adjust the distance from the camera and/or light to the base

Avoid light reflections on the PCB´s surface lowering the lighting ring. 

If you are taking photos of a large PCB, raise the camera as much as possible and frame it adjusting the camera’s zoom.

Below: the interative 3D model of the inspection platform. Check it for references.

AgnosPcb KIT components:

  • SONY Alpha 5100 camera with 16-50 lens

  • 336 Leds Lighting ring (dimmable)

  • Black 2020 Aluminium rail 

  • Frame’s plastic parts + bolts + wingnuts

  • methacrylate base + non-reflective layer

  • Battery dummy + USB cable

Place the methacrylate base over the platform and fix it using 8x M3 16mm bolts. Screw the bolts from the bottom of the platform. The base has to be perfectly horizontal. On top of it you will need to set the non-reflective layer provided with the KIT.


Check that the tips of the bolts do not protrude from the base surface


Insert the aluminium rail inside the platform. Be gentle. Capture the rail using a M3 16mm bolt from the back of the base


Use the screw indicated on the image to attach the plastic part to the LED ring (use a screwdriver)


The CAMERA´s arm comes with the wingnut and camera´s screw already placed. Fix the camera to the arm carefully. It has to be held firmly and pointing down. You will set the height of the camera on the vertical rail using the wingnut.

The same goes for the lighting LED ring. Its natural position will be 15-20 cm off the inspecting base but that distance may vary depending on the PCB size you are inspecting. Set the height and secure it tightening the wingnut


Below: How the inspection platform should look at this point. Place, on top of the methacrylate base, the non-reflective layer.


Connecting the system to a computer

The camera uses a battery dummy to be able to take photos continuously. The battery dummy has to be connected to a USB 3,0 or to the 5V charger provided with the KIT in order to get enough power to work properly.

At the same time, the camera has to be connected (using the provided USB cable) to a computer. With the SONY imaging Edge software (for Windows or Mac systems), you will be able to automatically store the photos taken, in a designated computer´s folder.


The LED lighting ring has 4 buttons. The light has to be ON during the inspection process. We recommend setting it to COLD/ white light and to increase it flux to the maximum. You can connect it to a 220 or 110V socket


Connecting the system to a computer. Part 2

1) Download and install the SONY imaging Edge software (for Windows or Mac)

2) Do not connect the Camera to the USB port yet

3) Check that the Battery dummy is fully inserted. Connect it to a USB 3.0 port or the 5V charger and turn the camera ON

4) CAMERA: open the SETTINGS MENU pushing the MENU button and go to SETUP-> TAB "3" -> USB CONNECTION and select "PC Remote"

5) Set the photography settings to: M (12MP) for medium or small PCBs and L (24MP) for large PCBs (around 25x20cm)*. 

 *The neural network can process both sizes, but the internet connection and integrity check operation will take more time to process larger images. So, if your PCB is about 10x15 cms, we recommend "M size" photos 

6) If you got the 16-50mm lens: SET the CAMERA to "INTELLIGENT AUTO" MODE. If you have the camera with the 50mm fixed system, check the paragraph (Using the 50mm FE 1.8 Sony Lens) to configure the camera properly.

7) Go to MENU-> CAMERA SETTINGS -> GRID LINES -> SQUARE LINES.  Displaying lines on the camera’s screen will be useful when placing the PCB on the inspection area.

8) Connect the USB cable from the camera to the computer and launch the REMOTE app. A pop-up message will appear

9) Select the ILCE-XX00 camera

10) In the REMOTE user interface, go to FILE-> SAVE FOLDER and select the folder in your computer where the photographs taken will be stored.

11) Try the system placing a photo on the inspection area (Is the Light ON?) and take a photo clicking on the SHOT button

12) The CAMERA will automatically autofocus on the PCB surface, but sometimes you will need to click on the AF button to force the camera to focus again.


13) The VIEWER will appear after taking the photo. Here you can zoom on the image using the mouse’s wheel. Check if all the elements on the PCB are on focus.

IMPORTANT: all the PCB to be inspected have to be perfectly leveled. If the board has a certain tilt angle, otherwise not all the elements will be perfectly defined and on focus on the photograph. 


Always try to set the CAMERA as high as possible before taking the photo, only lowering it to take a photo of small PCBAs.

Using the 50mm FE 1.8 Sony Lens

Agnospcb sony-e-50-mm-f18-oss.jpg

If you got the SONY camera with the SONY 50mm 1.8f fixed lens, follow these steps to set-up your system:


1)  Set the mode dial to A (Aperture Priority)

2) Select the value F8.0 by turning the control dial (right image). Setting the aperture to F8.0 will let you get the most detailed photos of your PBCAs


NOTE: Do not use the DIGITAL ZOOM with the 50mm optics system.  It will only artificially increase the size the digital image not adding real info to the photograph.

Detailed photos


If everything is fine, you will get highly detailed photographs of your PCBa. Above, example of two photos taken with the inspection platform. No shadows cast nor direct light reflections are present.
