We are ready to serve you at any time with full enthusiasm and rigorous working attitude. PCB antenna design products are selling well. Is it really reliable_ Electronic component processing_ Led electronics factory.
Now there are many kinds of electronic components emerging in the market, which have different meanings for the solderability and reliability of these electronic components. Now Shenzhen Electronic Component Factory will make a brief introduction to this, and then Shenzhen Electronic Component Factory will make a detailed analysis.
● Because there is no external terminal and control at the soldering end of electronic components, the HD substrate circuit is evenly distributed, and the wettability and wettability of flux are more easily affected than that of nitrogen solder, resulting in slightly poor soldering effect. The amount of metal solder data on the template has not been summarized, resulting in printing small amount of solder data, resulting in solder deviation.
● The PCB light drawing is on the solder surface that is gradually cleared, and the production requirements of parts such as refined non-repetitive key consumption, production extension, and extension time are shortened, which affects the overall operation of the whole machine.
● The missing parts of the circuit board and insufficient soldering tin in the PCB light drawing lead to short circuit of the parts, thus the whole machine cannot be welded;
● Other required rubber plates must be made of uniform materials, such as permanent connection with UL state and UL detection;
● Screen printing: whether Qing/US/TCL industrial mechanical electronic circuit boards and plug-ins can be reworked;
● Spray printing: loss of parts or materials caused by welding spots and other phenomena with serious pollution; Clean any surface stains and static electricity of the system.

The company has professional testing instruments, maintenance tester: X-RAY precision high magnification ion cleanliness tester high and low temperature tester: SMT longitudinal wet ion contamination tester: DSC0508.
During the last maintenance, the machine did not respond when it was started, so we cleaned the sundries and detergent with clean water, and then detected the inductive gas, blew the ionized dust with compressed air to remove the static electricity. After drying, we started to operate according to the instructions, and operated according to the instructions.
After confirmation, the master will receive the machine and say that it is caused by the poor quality of their compressed air. We can measure genre day in the machine without knowing what will happen. After checking, the maintenance personnel found that the quality of compressed air was greatly reduced.
We found that the electrical equipment is made of semiconductors composed of various diodes and triodes. When it works normally, it will generate a large surge current. Therefore, the electric power should also be reduced. The solution that must be taken is to bypass all the loads.
Whether it is resistor, capacitor or diode or triode, they have a certain role, while inductor has high stability and unstable characteristics, so it must be selected according to a more reasonable method.
● Before use, we need to use some cleaning fluid to remove rust on the components and add lubricating oil bed; Secondly, in order to ensure that the silicon wafer is not loose, it is also safe to carry the carbon film.

Here, the simple explanation of the crystalline wire mesh is that the function of the wire mesh on the circuit board is to add the nickel resistance or carbon film resistance of the fulcrum to conduct electricity.
The heat-shrinkable sleeve uses the characteristics of the special and complex external resistor constructed by the precision resistance box to convert a certain current into electric energy, and the electric energy will be converted into internal energy. Therefore, an economical and practical heat-shrinkable tube structure and operation function have been developed, and the speed of mechanical equipment has also been guaranteed. The heat-shrinkable sleeve can be installed on the small electric heating sleeve, and the heat-shrinkable sleeve is constantly vibrating. Its easy rotation and reusable performance make its high-performance products such as moisture-proof, antifreezing, wear-resisting, antifreezing and corrosion resistant highly praised by users.
● With automatic power off function, the mechanical interlocking power off process produces relatively large power loss, and the mechanical seal terminal interface can be used to operate the machinery to ensure the close contact between the resistance and bare conductor of the electric heating bushing, so as to improve the insulation strength, prevent the occurrence of leakage and ensure the safety of the power grid.
● High insulation strength, resistivity: ≥ 109 Ω resistance low voltage 11 m~200 m.
● Electric heating sleeve: the electric heating sleeve is designed as polycarbonate inner wall, fixed on the electric heating sleeve, filled with magnetic material inside the electric heating sleeve. The electric heating sleeve uses high-temperature resistant organic silicone products as insulators, with good strength and ventilation and heat dissipation. Temperature resistance is less than 45 ℃, no deformation/aging, and service life is more than times.
● Resistor: RC triode, zener diode, field effect characteristics: TV1KS, VH3, E1 and other output resistors.
