If the circuit board rusts, rust remover can be used to remove rust. What are the uses of printed circuit board assembly.
When using a groove blank as a component, in order to reduce the quality of the batch or whole batch, the component should be stored in the remaining area after two dry yards.
All components should be sealed with resin and sealing materials, both of which should not be affected by external environmental emissions or moisture. In order to facilitate the protection of circuits with gaps and their installation under conditions with gaps and preventing water immersion, nickel plating should be applied at the location of non-conductive ground codes.
The design of components should comply with our ergonomic and ergonomic requirements. Therefore, the size and shape of the equipment can be considered according to product design requirements.
● Perform integrated circuit protection on the protection system. Therefore, the main control circuit board must be designed and provide input/output drivers on the panel, such as NC/MODE drivers, DW01 drivers, level converters and/or expansion ports, and level converters.
To isolate the output capability provided by the main circuit board from the system output, copper film resistors and aluminum film resistors are used.
B. At the same time, ESD safety protection functions (overvoltage and undervoltage protection) have been added, which can prevent the system from electrostatic discharge noise.
● Does not assume ESD protection. Once the system is powered on or suddenly powered off, the system can maintain normal operation without affecting the normal operation of the system;
The CN11-1110SW series products are the damage caused by electrostatic discharge with added charge to the equipment (surrounding). When the area where electrostatic discharge current is generated exceeds 500nM (or 20mS) of space, the activity of electronic charges causes a decrease in ground potential, resulting in an increase in transmission resistance, causing the surge voltage of the electrical appliance to exceed the ground voltage of the power supply, or causing an electrical fire. ZDT-12C electrostatic discharge ESD tester is an infrared body temperature measuring tester, which has a USB interface and two static wires. When testing, it connects to the power supply through a whole set of system interfaces to realize the charging process of the Device under test, and radiates electromagnetic waves through the static wires to harm the human body. The product range is complete, with specially designed lightning protectors for high-density and high-precision measurement of equipment and instruments sensitive to lightning pulses. It can measure the characteristic parameters of the contact surface, contact surface material, ion generator, etc.
It can measure alternating current, alternating frequency, voltage, current, alternating frequency, voltage, current, frequency, impedance, number of turns, etc. It mainly measures the voltage, current, impedance, and frequency of power cables, cables, and structures.
