By the end of 2024, Bitcoin price is expected to reach $100,000! The crypto bull market is back. Bitcoin, the top cryptocurrency, could hit $100,000 by the end of 2024, according to a report by Jeff Kendrick, head of digital asset research at Standard Chartered Bank. By the end of 2024, we could see Bitcoin (BTC) reaching the $100,000 level , as we believe the much-hyped "crypto winter" is finally over. According to Kendrick, Bitcoin could benefit from many factors. For example, recent instability in the banking sector due to the end of the Fed's rate hike cycle and the increased profitability of cryptocurrency mining. As uncertainty persists, Kendrick believes the path to the $100,000 level is becoming more apparent. Bitcoin has bounced back this year, topping $30,000 for the first time in 10 months. However, the crypto industry lost trillions of dollars in 2022 after the Fed raised interest rates. Observers Are Arguing About Bitcoin Standard Chartered isn't the only
What should be paid attention to in operating and using the reflow soldering machine?
The reflow soldering machine is essential production equipment for the welding process in the SMT production process. It is responsible for melting the solder paste on the circuit board with the mounted components to weld the patch and circuit board pads. What are the precautions for the use of the reflow soldering machine are the knowledge that SMT operating technicians must learn? What is the function of the reflow soldering machine, and what should be paid attention to in operation and use?
What is the function of the reflow soldering machine?
The reflow oven is mainly a desktop reflow equipment used for producing and maintaining SMT and other products. ZB2015HL reflow soldering machine precisely controls the temperature curve through the precise control of the microcomputer so that the temperature of the reflow soldering plane is more uniform. In addition, its temperature curve is precisely adjustable, and the device also has automatic fault detection and reporting functions.
Precautions for reflow soldering machine operation:
1. When producing different models, you should first adjust the width of the reflow soldering track using the rocker above the power switch, depending on the width of the substrate. Generally, the width of the track should be about 1.5mm larger than the width of the substrate;
2. The temperature control range conforms to the specifications in the manual, and the control accuracy is within ±2.0°C; the speed control conforms to the specifications in the manual, and the accuracy is controlled within ±0.2m/min; the lateral temperature difference of the substrate movement (≤150mm spacing) is within ±10.0°C;
3. The appearance of the heater is complete, and the electrical connection is reliable. The hot air fan runs smoothly without noise; the guide rails can be adjusted freely and parallel. The effective width of the transmission substrate conforms to the specification index;
4. The operating system is working normally; the appearance of instruments and meters is intact; the indications are accurate; the readings are eye-catching and within the qualified service life; the electrical devices are complete, the pipelines are arranged in order; and the performance is sensitive and reliable;
5. After starting up or adjusting the temperature, curing or welding cannot be performed immediately because the temperature at this time has not reached or exceeded the set temperature, and more defective products will be produced immediately; only when the signal light is always on, the furnace cavity The temperature can reach the required temperature;
6. The alarm will sound when the induction times out or a substrate falls in the furnace. You should open the furnace cover first to check whether a substrate is falling into the furnace. After clearing, click "Remove Alarm" on the interface and then click "Reset";
7. Production conditions: For the safety of machines and products, the production shall not exceed the following range; the length and width of the substrate shall not be less than 50mm×70mm and shall not be greater than 310mm×330mm. It cannot exceed the upper part of the track by 25mm and cannot exceed the lower part of the track by 18mm;
8. Pay attention to protecting the touch screen of the machine at ordinary times to prevent failure after heavy pressure and sharp scratches;
9. In case of an alarm in an unfamiliar situation, overspeeding of the chain, or a sharp motor sound, immediately press the red EMERGENCY STOP button to cut off the main power supply. Report to the manufacturer for a solution.
