In recent years, the automatic soldering equipment industry has received attention and its development potential is unpredictable. Five highlights of the latest development in the rigid-flex board industry. The new visual automatic soldering machine has the following functions: improving accuracy, reducing blind spots, reducing false soldering, avoiding crossing, blocking solder pads, and other soldering processes. The structure of the fully automatic soldering machine itself is a pure mechanical component, the mechanical structure and control system of modern automatic soldering machines, including basic positioning system, fixture, welding head, fixture, landing platform, various angle electric control, fixture, safety valve, air source, peripheral protection system, liquid storage tank, handle, power line, circuit board, stepper motor, piston, etc.
Automatic soldering robots are particularly suitable for welding products such as household appliances and digital products. However, traditional manual operation is difficult to meet practical requirements. Therefore, automatic soldering robots are particularly suitable for welding connectors with dense solder joints. However, automatic soldering robots have the following characteristics.
Welding work is stable and has good repeatability. Due to the advantage of repeatability, even when welding components on adjacent boards, the welding efficiency between each component remains unchanged.
After welding, cleaning can be carried out. Use a non-alcohol spray gun as a cleaning tool for the inspection specimen.
Conduct integrated circuit pin trimming and check if there are any issues with the entire circuit, especially some parts of the signal processing circuit.
Test each pin for short circuits. If a fault is found, immediately shut down the machine and measure it with a multimeter to see if there is a problem.
If there is a fault code displayed indicating that the printed circuit board has a fault code, the entire circuit board needs to be replaced until it is repaired.
Some circuit boards do not have certain internal protection and external measures, such as overload, overvoltage, short circuit, etc., which may cause overheating or damage to the circuit board or components.
For various power devices, some circuit boards cannot achieve their own power consumption, such as power amplifiers and comparators. If the load resistance at the output end exceeds the normal value, it will increase its heat generation; In addition, some power amplifiers have high power consumption (such as lighting load resistors or heat dissipation processing devices), which reduces their performance.
The power consumption of switching power supplies is mainly determined by the feedback circuit, and the operating frequency of switching power supplies can generally be several thousand hertz, even a few megahertz, or even several tens of megahertz.
The working frequency of the pulse width modulation circuit cannot be fully modulated by PWM, otherwise it will cause power consumption and sometimes lead to system oscillation.
Rated current refers to the maximum value of the conduction resistance of the switch tube within the specified range, and the maximum value of the inductance and capacitance when the switch tube operates normally at the specified ambient temperature.

The temperature range of the working environment refers to the working temperature range of all circuits or control components that need to be controlled within the working temperature range when the static (single state) working point is at room temperature.
