What the piss happened to my sensor?! This has never happened before. I bought a cleaning kit and cleaned it myself. It took ages though. I hope this never happens again!

My 400D is a bit over a year old now with around 25000 actuations (bought new). Never cleaned the sensor. Attempted to clean it today but was not very successful. Need better tools I think.

I picked up a second time my old Konica-Minolta Dynax 5D (an APS-C DSLR see details below) for an extra tour of the warm-humid tropical green houses at the Botanical Garden of Lyon, France.
This time I fitted to the camera its dedicated macro lens Sigma 1:2.8 DG f=50mm (equivalent to 75mm full-frame 24X36 format) . For this tour, I used a CF card 16GB giving almost unlimited number of possible RAW files (1694 !) .
I also used a fix 200 ISO sensor sensitivity. I had in mind to limit the session to 36 images as a regular 35mm film cartridge, but I finally did about 60 … The lens was equipped with a generic Anti-UV protective 55mm filter and its original Sigma shade hood.
Whenever necessary in low-light conditions, I used the build-in small flashlight (NG 12 at 100 ISO) to complement the ambient light and to restore vivid colors. The camera was used either in the manual « M » mode or the aperture-priority « A » automated mode.

After the session, the RAW files were transferred to the computer using a USB multi-memory cards reader and processed in the latest version of Adode Lightroom Classic (LrC version 14.1.1) that uses the external module Adobe Camera Raw version 17.0.1 for the RAW files development. The files were then processed as usual using the regular functions of Lightroom. They are presented either as printed files with frame or the full-size JPEG's.
About the camera :
I bought my Konica-Minolta Dynax 5D (an APS-C DSLR see details below) brand-new in the winter 2005-2006 after using intensively a Minolta Dimage 7 that was a futuristic early mirrorless digital camera. I got the camera as a bundle kit including a AF DT Zoom 18-70 mm / f3.5-5.6 (D) lens, a tele zoom lens AF 75-300 mm / f4.5-5.6 (D) lens, and a very nice macro lens Sigma 1:2.8 f=50mm DG that I used principally for documenting small horological objects.
The Konica Minolta Dynax 5D is a Digital SLR camera announced by Konica Minolta on July 15, 2005. It is also known as Maxxum 5D in the USA and (Alpha) αSweet Digital in Japan. It became available from September 2005 and was bundled with the AF DT Zoom 18-70 mm / f4.5-5.6 (D) lens.
The camera features a 6 megapixel CCD sensor. Image files are created at a maximum resolution of 3008 x 2000 pixels and recorded in JPEG (STD, Fine, EX-fine), RAW and RAW+JPEG formats. It uses CompactFlash for storage. The back has a 115,000 2.5" TFT color display.
Main differences between the 7D and the 5D are:
* Less buttons and dials
* Fibre plastic body, as opposed to a magnesium alloy on the 7D, camera is almost 200 g lighter (970g in workin order with the AF DT Zoom 18-70 mm)
* White balance bracketing
* Newly added colour modes, including black and white
The Konica-Minolta was the last DSLR camera engineering before the cession to Sony of the whole photo camera activities of the company.

5G PCB Development
As a new generation of revolutionary technology, 5G not only means an exponential increase in data transmission speed but also a truly converged network, which will promote related application fields, such as the Internet of Things, Industry 4.0, Artificial Intelligence. Telematics and interactive multimedia applications will be popularized, thus forming the "Internet of Everything" era.
PCB as the "mother of electronic products", the profound changes in the downstream consumer market will directly affect the development trajectory of the PCB industry. The industry generally believes that the next three to five years 5G communications will surpass today's intelligent terminals, automotive electronics two major application markets, the first engine to drive the growth of the PCB industry.
Requirements for 5G PCB Design
The selection of boards to meet the requirements of high frequency, high speed.
Impedance matching.
The planning of the layer stack.
Wiring and hole spacing to meet the signal integrity requirements.
The operator can consider 5G PCB design specifically from the loss, buried, high-frequency phase or amplitude, mixed voltage, heat dissipation, PIM these six aspects.
PCB Telecommunication Overview
PCB telecommunication demand is divided into segments such as communications equipment and mobile terminals. Communications equipment is mainly used for wired or wireless network transmission of communications infrastructure, including communications base stations, routers, switches, etc. Communication equipment mainly uses high multi-layer PCB telecommunication boards, of which 8-16 layers account for about 42% of the mobile terminal is dominated by HDI and flexible boards.
Other PCB Assembly Applications
I see sensor dust - lots of it - balls. That means I need to get in there and clean it off. New territory for me. Any tips would be welcome.
