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 adjus...

What should be paid attention to when using an oscilloscope? The oscilloscope is an indispensable measurement tool used by maintenance engineers, but various problems will be encountered during oscilloscope use. This article sorts out the common problems in using the oscilloscope for you to solve the doubts of the operation and maintenance personnel. 1) Q: What is the fixed relationship between bandwidth and sampling frequency? A: At least 2 points need to be sampled in each cycle of the highest frequency signal of the measured signal; otherwise, aliasing will be caused. But in practice, it depends on many other factors. Generally speaking, the sampling rate is 4-5 times the bandwidth, and the waveform can be reproduced more accurately. 2) Q: How to understand the bandwidth in the oscilloscope indicator? A: Bandwidth is the basic indicator of an oscilloscope. Like the definition of amplifier bandwidth, it is the so-called -3dB point, the frequency point at which a sine wave is added to...

How to use the soldering iron and matters needing attention The electric soldering iron is a very simple and common tool for welding. It is very convenient to use. It can be used for electronic production and electrical maintenance welding wire components. So, how to use the soldering iron correctly? What should we pay attention to when using it? Through this article, let's find out together! How to hold the soldering iron? There are three main ways to hold the soldering iron: ① Reverse grip method, that is, use five fingers to hold the handle of the electric soldering iron in the palm. This method suits high-power electric soldering irons and welding workpieces with large heat dissipation. ② Positive grip method, hold the handle of the soldering iron with four fingers and press the thumb along the direction of the soldering iron. This method is suitable for larger electric soldering irons and is generally used for curved soldering iron tips. ③ Hold the pen method, that is, use th...

How to use the submerged liquid-cooled miner box? Miners need to perform high-density operations to obtain virtual currency. Therefore, the hash board will generate a lot of heat during the operation of the miners. Suppose the heat cannot be discharged in time, the miners run in a high-temperature environment, which may cause the miners to shut down for protection and short-circuit the internal circuit or even burn out essential components. As the difficulty of obtaining virtual currency continues to increase, the hash rate required by miners continues to increase, and the heat generation also continues to increase. As an essential cooling kit for cooling miners, the immersed liquid-cooled miner box is deeply loved and praised by most miners in the market. I will also briefly introduce its working principle and usage instructions for your reference. 1. The working principle of the submerged liquid-cooled miner box The miner's hash board transfers heat to the oil during use, and the...

How to use the Avalon debug D signal short circuit board? Purpose of the Avalon debug D signal short circuit board: When testing an Avalon single-hash board, the test fixture reports 0 or the number of chips is incomplete, and the Avalon debug D signal short circuit board can be used to locate the faulty chip quickly. When in use, you only need to press the switch, short-circuit the clip to connect to the D signal on the board, and you can replace the oscilloscope to find the fault point, which is very convenient to use. Avalon debug D signal short circuit board applicable models: Avalon A10 series, A11 series, A12 series Avalon debug D signal short circuit board interface description: ①: Short-circuit the positive pole, connect the D signal test point that the chip needs to be short-circuited ②: Short-circuit the negative pole, connect the negative pole of the power supply where the chip signal to be short-circuited is located, which is the domain voltage Vcor...

How to use Avalon hash board tester? Avalon hash board tester tests data such as signal path status, number of chips, ASIC temperature data, ASIC core voltage, etc. It is a professional high-quality chip test fixture that integrates application board testing, core board testing, driver board testing, and various accessories testing. Help miners quickly understand the status of the Avalon miner hash board and accurately locate the fault of the hash board chip. Avalon hash board tester is suitable for Avalon miner A10 series, A11 series, A12 series, etc. Avalon hash board tester interface description: 1. Original power interface (6Pin) Please do not connect the PC power supply to this interface. Otherwise, it will easily cause the device to burn! This interface is used to supply power to the hash board tester for the PSU that comes with the miner. Unplug the 6pin cable of the control board of the miner and connect it to the hash board tester. Power the hash board using the power cable t...

How to choose a suitable fan simulator for the miner? There are many types of fan speed simulators ; how to choose? What is the functional difference? This article will help customers fully understand its functions and features through the fan speed simulator selection guide. 1. Definition of the fan interface: All cooling fans  (including CPU, GPU, miners) are defined according to the PWM standard interface, namely black cable (GND, ground cable, usually connected to negative pole), red cable (VCC, positive pole), 12V), yellow cable (SENSE, signal, speed cable), the blue cable (CTRL, control cable). Actually, they have 3 kinds of cables: Two-cable fan (black, red): there is no speed measurement function, and the speed can only be achieved by controlling the voltage and is generally used for heat dissipation of miner chassis fans. Three-cable fan (black, red, yellow): Add a speed measuring cable, which can detect the fan's speed but cannot realize the speed. It is generally used fo...
