Communication with copper-colored tin solder. Simple recipes and tips
Directory / Factory technology at home - simple recipes
Comments on the article
As you know, tin is most often used for soldering copper parts, but such solder has one drawback: in soldering places, tin is ugly distinguished by a white spot or a white stripe against the copper background of the soldered parts.
To eliminate this drawback, the following simple technique is recommended: the solder points are covered with a saturated solution of copper sulphate, for which 10 parts of vitriol are dissolved in 35 parts of water and the coated parts of the solder are then rubbed with iron wire and in this way copper soldering, after which the adhesion is again coated with a solution of 1 part of saturated copper sulfate and 2 parts of saturated zinc sulfate and rubbed with a zinc stick.
The soldering points treated in this way can be polished, and then the protruding parts of the tin solder completely merge with the copper tone of the soldered parts.

Solidification of bulk substances
30.04.2024
There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>
Implanted brain stimulator
30.04.2024
In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>
The perception of time depends on what one is looking at
29.04.2024
Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>
| Random news from the Archive 10K TV
16.06.2015
The Chinese company BOE introduced a TV with a 10K format panel. Its resolution is 22 times that of Full HD and 5,3 times that of Ultra HD. While the release of such devices is impractical. The product was presented to demonstrate the capabilities of the supplier.
Chinese panel supplier BOE Technology Group unveiled the world's first 2015-inch 82K TV at Display Week 10 in California, according to Heise.
TV panel format - 21:9. Its resolution is 10240 x 4320 pixels, that is 44 million pixels. This is 22 times more than Full HD (1920 x 1080) and 5,3 times more than Ultra HD or 4K (3840 x 2160).
The pixel density in the BOE TV matrix is 135 ppi, so it is difficult for the viewer to see the pixels, even if he is near the screen. By comparison, a 50-inch Full HD TV has a pixel density of 44 ppi.
BOE hasn't said if they plan to mass-produce an 82-inch 10K sensor. Its release serves only the purpose of demonstrating the technological capabilities of the Chinese manufacturer and the Chinese industry as a whole.
At present, the Ultra HD format is gradually gaining popularity, the resolution of which is 5,3 times less than in the TV presented by BOE. Even if the company decides to release its own panel, content of this format does not yet exist on the market. In addition, it will be necessary to develop new media for storing it, since the capacity of a modern Bluray disc will not be enough.
BOE Technology Group produces panels for TVs, monitors and mobile devices. It was founded in 1993 in Beijing and is one of the largest players in the LCD panel market in China.
