Storage, holePanels, drawers, and storage boxes are all helpful for efficient storage. In terms of brands, Lege LIFT1 and North Arc M1 are the top table recommendations, while mice such as Razer Viper V2 and Logitech MX Master3, keyboards such as ROG Flare 2 magic (Hawthorn red axis) and Jingdong Jingzaoji add to your operating experience.
Desktop transformation ideas and good things recommend the choice of table and upgrade the core of the table is practical, when choosing a table, the lifting table is a wise choice for healthy office, such as the North arc song, when the budget is sufficient, you can not hesitate. If the budget is limited, fixed height tables are also availableCan provide a stable work space.
Desktop Angle: mechanical and pneumatic adjustment, scientific Angle makes learning more comfortable. Table and chair: neat or L-shaped partition, comfort and function. Brand insight: Quality and price competition On the market, there are old best choices such as Sihao and black and white tone, and there are emerging brands that attract attention with innovative technology. I compared 14 major brands, covering a wide range of price points, with a focus on user reviews and product safety.
The height and Angle of the intelligent learning table can be adjusted, and the seat can be lifted and lowered, so you don't have to worry about the child's sitting position anymore.And the intelligent learning desk storage function is also very good, winter vacation observation, children will more and more pick up things, desk tidy up orderly, learning efficiency is also higher.
First from the east of the room to decorate it warm color wallpaper home if you want to be very warm must make the room have a warm feeling, I recommend warm color wallpaper such as pink, yellow. Try not to choose dark colors, because it will make the room become dead, and feng shui is not very good. Covered with wallpaper room immediately tall and still, a kind of foreign pastoral feeling.
Advantages Practical drop shaped shape design, savingHome space. The water drop-shaped luxury stone table adopts circular design, which has lower space occupancy and can expand visually with depth; Round curved table with glaze, feel silky, high safety index.
1, the disadvantage of the hole board is that it is relatively troublesome to debug the replacement hole board wireless charging , and the degree of beauty is certainly not very good hole board wireless charging , it is difficult to clean the dust, and slightly heavier things are hung upIt is easy to drop the hole board wireless charging , if a hole is damaged need to replace the whole board. The advantage of the hole board is convenient storage, in addition to having a strong storage function, the hole board is also a good thing for home decoration. Its simplicity and variability form a personalized storage space, worthy of being a universal storage artifact in space.
2, the universal circuit board is a printed circuit board that is covered with welding pads according to the standard IC spacing (54mm), and can be inserted with components and connections according to its own wishes, commonly known as "hole board". Compared to professional PCB platemaking, cavity boards have the followingAdvantages Hole plate wireless charging : low threshold of use, low cost, easy to use, flexible expansion.
3, yes, if the chip holder is not used, it is easy to transfer heat through the chip pin to the inside of the chip during the welding process to damage the chip, in addition, during the welding process, the electric soldering iron head will have static electricity, which is conducted into the chip through the chip pin, thus damaging the chip.
1, circuit board production method: First of all, start from the raw material board, according to the predetermined sizeCut the circuit board. Then, the automatic drilling machine is used to drill holes according to the designed circuit diagram, and then the polishing machine is used to polish. After that, prepreg, wash, and dry the ink with a curing machine at 75 ° C. Next, the activation treatment is carried out, and the through-hole effect is checked through the through-hole process, and then cured and dried at 120 ° C.
2, the printed circuit board will be drawn with transfer paper printed out, pay attention to the sliding side facing themselves, generally print two circuit boards, that is, print two circuit boards on a piece of paper. Select the best printed circuit board. Cutting copper-clad plates to make electricity from photosensitive platesDiagram of the road board.
3, the production of PCB circuit board generally includes the following steps: Design circuit diagram: Use circuit design software (such as Eagle, Altium Designer, etc.) to create a circuit diagram and connect various electronic components. Layout design: Layout design is carried out in the PCB design software to determine the position and routing path of each component. Wiring: Use the wiring tool in the PCB design software to connect and ensure that each component is correctly connected according to the design requirements.
4, circuit board production principle Circuit board production principle mainly includesThe next few steps: Design the circuit: First, according to the function of the circuit, design the circuit diagram, determine the component components of the circuit, and the connection mode between the components. Make schematic diagram: According to the circuit diagram, make schematic diagram to determine the position of the components on the circuit board, and the connection mode between the components.
5, the production of copper coating plate according to the size of the printing layout, so that it is consistent with the size of the actual circuit diagram, and keep the copper coating plate clean. The circuit is printed on the copper coated plate and the wax paper is laid on the steel plate. The printing layout is engraved on the wax paper in a ratio of 1:1 with a pen, and the printing layout on the wax paper is cut according to the size of the circuit board2 >
Use the pin of the component: the ground connection power supply of the hole plate needs a lot of jumper, jumper, etc., do not rush to cut the excess pin of the component, sometimes directly across the pin of the surrounding component to be connected will get twice the result with half the effort. In addition, for the purpose of saving materials, the cut component pins can be collected as jumper materials. Setup jumpers: Multiple setup jumpers can not only simplify the connection, but also be much more beautiful.
When you connect the power supply and the line, you can use a single point grounding method, that is, the second half of the sentence you said, all the GND are connected to a point respectively, and then groundThis method is more advantageous to reduce interference. It's not a problem with the power supply. You can go in sections. PS: Give you a suggestion, use a row of pins to weld multiple groups of power and ground sockets, so that when expanding later, it is more convenient to take power and ground.
The grounding on the circuit is the so-called virtual ground, that is, the reference level is defined as the reference point of 0V, all the node voltage on the circuit is relative to this reference point, rather than directly connected to the ground, such as electrical equipment needs to be directly connected to the ground will be specified, you here the experimental circuit does not need to connect to the ground; This is a conceptual problem in learning electronic wiresYou have to figure it out first.
This is complicated enough that you need to do the board directly. The hole board will be a mess after use, there is no way to debug. If you lack experience, you can look at the recent radio magazine, which introduces many single-chip microcomputer experiment boards, and is welded complete, providing learning materials and procedures. I am not familiar with single chip microcomputer, for reference only.
To have a power supply, it can be a transformer rectifier DC power supply, it can also be a few batteries and so on. GND means ground cable. All the GND points should be joined together. It should also be connected to the negative of the power supplyExtreme. The power outlet should have a switch to control the power or power off of the circuit.
The negative electrode of the general circuit power supply is the ground, and there should be no other side to be connected except the negative electrode of the ground power supply.
