What are the points to pay attention to when stamping and bending hardware parts? What are the characteristics of rigid-flex boards? We will know by grasping these features.
Metal stamping and bending parts are generally carried out at temperatures below 100 degrees Celsius, and the hardness of vibrating magnetic steel is 4H1 at 25 degrees Celsius. Therefore, all metal materials are processed.
The production process of pressure welded steel is crucial for the development of technical personnel, and many processes and technologies are adopted in material selection. Below, we will mainly introduce what is pressure welded steel material,
The principle of electric welding is to use the principle of heat recovery for welding. The principle of electric welding is to weld steel parts or thin-walled steel materials by brazing and processing steel. The main welding material used is copper foil or aluminum.
The high-frequency heating characteristic is that in the electronic field, when the temperature at both ends of the heating element exceeds a certain threshold, an alarm is triggered and the power switch is immediately turned on. The fault indicator light lights up and a beep sounds.
High temperature welding efficiency refers to the use of thermal radiation and metal powder insulation material to generate heat when the voltage at both ends of the component drops to a certain threshold in the electronic field. A relatively simple method is to sharply reduce the temperature of the metal powder to the upper limit of the weighing value, which refers to the degree to which a key parameter affects the electronic component. High temperature welding mainly refers to electronic equipment power, voltage and current, resistance welding temperature, etc.
At present, the thermal power of electronic components mainly includes the ability of thermal expansion, heat dissipation, and damage. When welding, the temperature per minute reaches around 200-100 ° C, and the lifespan of metal resistors is approximately over a hundred yuan.
When welding, the temperature can reach 100 ° C per minute, and the maximum temperature with an electric soldering iron can reach around 300 ° C, but it cannot exceed the maximum temperature of the furnace.

The power of an electric soldering iron is related to time. The faster the temperature rises, the longer or longer the welding time, and the possibility of burning the resistor. Therefore, when designing, it is best to keep the power in a critical state and minimize the final time as much as possible.
The electric soldering iron should be reliably grounded, and the effective grounding area of the power supply and the connection of the ground wire should be as much as possible to reduce the radiation emission of the power supply. It is recommended to avoid installing an electromagnetic calorimeter on the power connector. When there is only a fire source and a fire source, the power supply can be directly connected to the cathode or a metal object with the cathode to the ground.
The AC power of the LED driver power supply is the magnitude of the pulsating DC voltage. In this order, the voltage of the AC power is proportional to the frequency of the AC power. In this way, the voltage generated by AC power through the power line (such as line to line voltage) is directly proportional to this part of the voltage, and different AC voltage can be output to the load through this voltage.

So what is the impact of AC on switching power supplies? If AC power passes through a switching power supply, the voltage pulse width increases and the current increases. The iron core and wire slot of the transformer are dominated by a balanced winding, and this increase in the number of turns only increases the wire voltage. The wire voltage of a transformer is wire.
Figure 2 shows the waveform of transformer wire voltage. During normal operation of the transformer, the wire voltage significantly decreases. If it is the wire voltage, the lower the voltage, the lower the transformer voltage;
