How motherboards are made

The researchers then experimented with salt and ethylene carbonate, which is commonly found in lithium-ion batteries, and achieved a temperature change of 25°C using less than one volt, a significant improvement over other caloric alternatives to cooling.

After receiving a provisional patent, the authors plan to develop a prototype. In the future, the method can be used for water heating, industrial heating or cooling.Motherboards are the foundation of any modern electronics. They are the ones that connect the rest of the system components together. Motherboards are quite complex electronic devices, but how are they made? In our material, we will consider their production using the example of motherboards for personal computers.



is divided into two stages. The first stage is the production of printed circuit boards. The second stage is the assembly line, where all the necessary electronic components and connectors are installed on the printed circuit board.

Creating a PCB
The process of creating a motherboard starts with the honduras number data production of printed circuit boards. The production processes of this stage are automatic, but people monitor their parameters and help them in their work. The birth of the board begins with the creation of its base - textolite. For modern motherboards, multilayer textolite is used.



To obtain one layer of PCB, thin sheets of fiberglass are impregnated with epoxy resin and sent under a press. After that, a layer of copper is applied to the resulting workpiece, and a layer of photosensitive material - photoresist - is applied on top of it. A special machine illuminates the surface of the workpiece according to the photo stencil loaded into it, and copper-etched traces are formed in the illuminated areas. Then the remaining copper with the unexposed photoresist is sequentially washed off in several baths with chemicals. After all these procedures, the layer of our future board is ready. In terms of its properties, it is similar to thick paper.



"We have a completely new thermodynamic cycle and structure that combines elements from different fields, and we have shown that it can work. Now it is time for experiments to test different combinations of materials and techniques to solve engineering problems," the scientists note in an article recently published in the journal Science.
