In 2023, is it suitable to use miners to mine or buy coins?

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

What are the commonly used adhesives in circuit boards?

What are the commonly used adhesives in circuit boards?

In the repair and welding of circuit boards, we will use a variety of glues, but the following five are the most common; let's take a look!

1. Thermal grease

Thermal grease, also known as thermal paste, is a high thermal conductivity silicone insulating material. It can also be used for a long time at a temperature of -50 ~ +300 ℃ to maintain a grease state. Thermal grease has high thermal conductivity, excellent thermal conductivity, and a wide operating temperature. In addition, it is non-toxic, odorless, and non-corrosive, meets ROHS standards and relevant environmental protection requirements, and has stable chemical and physical properties.
Thermal grease
The primary function of thermal grease:
Thermal grease is mainly used to fill the gap between the heating element and the heat sink to increase their contact area to achieve the best thermal conductivity. In addition, good use stability and good construction performance can effectively reduce the temperature of the miner's hash board so that the heat of the electronic components can be effectively dissipated and transmitted, ensuring the miner's smooth operation and service life.
The thermal grease is widely used in CPU graphics processors, notebook and desktop computers, high thermal conductivity modules, automotive headlight control, cooling devices, power conversion equipment, network communication equipment, electronic components, etc. It acts as a heat transfer medium and dramatically improves the heat dissipation effect.

2. Silicone glue

Because silicone glue is often used for bonding and sealing glass, it is commonly known as glass glue, and the glue should be sealed and stored. Silicone glue is a material that solidifies into a rigid, rubber-like solid when exposed to moisture in the air.
Silicone glue
The primary function of silicone glue:
Silicone glue is widely used in electronic modules, sensors, electronic components, and other occasions where potting, insulation, and flame retardant are required, as well as the bonding of electronic components and the insulation between fixed components.

3. Hot melt adhesive

The hot melt adhesive strip is a solid adhesive made of ethylene-vinyl acetate polymer (EVA) as the primary material, adding modified rosin resin or petroleum resin and other ingredients. It is a plastic, non-toxic, tasteless, green and environmentally friendly adhesive. The physical state of the hot melt adhesive changes with the temperature within a specific temperature range, while the chemical properties remain unchanged. It does not contain water or solvent at all and has the characteristics of fast adhesion, high strength, aging resistance, non-toxicity, good thermal stability, and film toughness.
Heat the hot melt adhesive to the operating temperature, use a spray gun or coat it on the adherend, complete the bonding and shaping work within the glue's available time, clamp the adherend and cool it to room temperature. Hot melt adhesive is solid at moderate temperature, heated and melted into liquid, and cooled at room temperature to complete bonding within a few seconds, which can effectively fix electronic components and wire harnesses.

The primary function of hot melt adhesive:
Hot melt adhesive can be used for fixing electronic components, electronic bonding wiring, and bonding other electronic materials. It can even be used for mutual bonding, fixing handicrafts, packaging cartons, accessories, wood, textile samples, etc.

4. Red glue

Red glue is easy to cure after being heated. It is a polyolefin compound. When the temperature reaches 150 °C, the red glue changes from a paste to a solid. It is precise because of this characteristic of red glue that it is used to fix SMD components by dispensing or printing. The circuit board components can be heated and cured by oven or reflow soldering using SMD red glue.
Red glue
Several characteristics of red glue:
① Stable adhesion of various chip components;
② It has viscosity and thixotropy suitable for screen printing, and the amount of glue is stable without brush leakage or tower edge;
③ It has good storage stability;
④ It has high adhesive strength, which can avoid the misalignment of components during high-speed placement.
The primary function of red glue:
Red glue is used to fix the SMD components of the circuit board, mainly for bonding, or used together with solder paste for reinforcement and fixation.

5. Yellow glue

Yellow glue has a pungent odor and is a soft self-bonding water-based adhesive with excellent insulation, moisture-proof, shock-proof, and thermal conductivity, enabling electronic components to operate safely under harsh conditions.
The curing speed of yellow glue is related to the change in ambient temperature: the higher the temperature, the lower the humidity, the greater the wind speed, the faster the curing speed, and vice versa. Therefore, when the coated parts are placed in the air, there will be a phenomenon of slow skin formation. Note that the operation should be completed before the surface is skinned.
Yellow glue
The primary function of yellow gum:
Fixed inductors, coils, transformers, electrolytic capacitors, receiving heads, and other electronic products can protect and seal electronic components and be used for electrical components potting, moisture-proof circuit boards, etc.
