In 2023, is it suitable to use miners to mine or buy coins? In recent years, with the increasing popularity of blockchain technology and the rapid development of digital currency, more and more people have joined the team of mining and buying of coins. In 2023, for most people, choosing to use a miner to mine or buy coins will be a critical decision. Advantages and disadvantages of miners High power consumption, high cost, and high technical requirements are the salient features of miners' mining. But at the same time, miners also have a stable income from mining and have the advantage of controlling the speed of block verification. Here are a few viable Bitcoin miners and their profitability in 2023. Antminer S19 Pro is a miner produced by Bitmain , which is very popular in the market. It is equipped with 114 BM1398 ASIC chips , which can achieve a faster and more stable mining experience. It is estimated that the average daily income of this type of miner in 2023 will exceed 120
Electronic components installation precautions
The electronic devices used in our daily lives depend on the installation and use of electronic components. For a professional engineer, mastering the installation method of electronic components can be said to be an essential skill. So today, I will introduce the precautions for installing electronic components!
1. Before installation, the pins of electronic components should be wiped clean. It is best to wipe with a fine emery cloth to remove the oxide layer on the surface so that it can be easily tinned when soldering. However, if the pins are coated, wipe as appropriate.
2. According to the installation method, the components can be installed vertically or horizontally, as shown in Figure 1. For components that can be installed in two ways, when the operating frequency is not too high, two installation methods can be used; when the operating frequency is high, the components should be installed horizontally, and the leads should be as short as possible to prevent the influence of high-frequency parasitic capacitance circuit.
3. When installing large and heavy components, in addition to soldering on the circuit board, it is best to fix them with brackets to make them more solid and reliable. Figure 2 is a schematic diagram of the fixing method of the heavy component mounting bracket. In the figure, the high-power triode is fixed on the angle aluminum plate with screws and then fixed on the mounting plate. In this way, one is stable, and the other is the aluminum plate can play the role of heat dissipation.
4. When installing various electronic components, the side marked with the component model and value should face up or out so that the component model data can be checked at a glance during welding and maintenance, as shown in Figure 3.
5. When extended component leads need to be retained, insulating conduits must be covered to prevent component pins from colliding and short-circuiting.
6. The installation of components should be beautiful. When installed vertically, the components should be perpendicular to the circuit board, and when installed horizontally, they should be parallel to the circuit board or attached to the circuit board.
