There are two types of separated and non isolated switching power supplies, which are the "difficult problems" in the design and manufacturing of "isolated" printed circuit board assembly. Understand the precautions for power component manufacturers when designing switching power supplies.
Equipped with power components and integrated with self recovering MOSFETs, with minimum voltage and high current. 2、 Main features.
Equipped with a comprehensive multi bus interface and a maximum of filtering capacitors, each type of inter board power supply can be switched to multiple modules.
With the continuous innovation in the automotive industry, the application fields are becoming increasingly widespread. The size of electronic products is increasing day by day, and their application fields are becoming increasingly complex, such as automotive electronic control units, automotive domain control units, automotive display screens, automotive safety systems, automotive components (such as engines, automotive air conditioning, chassis control units, safety sensors, engine control units, safety sensors, automotive entertainment equipment, automotive power systems, automotive diagnostic systems, automotive control units, etc.).
The electrical system of new energy vehicles is a variety of functional components on the vehicle, and its main functions include safety protection, power distribution, signal monitoring, signal transmission, and fault protection for various electronic devices. But these functions are crucial for the use of lighting fixtures.
Modular electronic and power equipment systems require universal and multifunctional electronic and electrical chips or modules (such as batteries or printed circuit boards).
There are many types of power electronics technology, such as power motors, batteries, etc. They have the advantages of high efficiency, programmability, scalability, security, reliability, and ease of implementation.
With the continuous development of technology, analog products are composed of many parts, and the application of this type of technology will gradually mature, but it needs to rely on analog and digital circuits. In order to achieve simulation functions, a series of circuit components combined with analog integrated circuits are required to provide a system with advantages such as high reliability, high accuracy, and ease of implementation.
Without welding, static electricity, high temperature, and high humidity can all cause solder joints and assembly connections to fail or become loose. During assembly and equipment, static electricity may cause electrical characteristics to fail and may lead to component functional failure or functional failure.

Static electricity may cause a short circuit to the PCB casing, leading to component functionality failure. Just like the KING connector used in semiconductor radios, the KING used in aerospace models.
Static electricity may cause damage to PCBs, such as metal conductors, which should be wrapped with various conductive materials (metal foil). If the integrated circuits and components on the PCB are in poor contact, it is also easy to cause static electricity shock, which can cause harm.

The copper clad plate often falls off after eating tin during the cooling process of the weft glue separation machine. The reasons are summarized as follows.
The surface of the copper clad board is uneven in adhesive printing. If there is no PCB board that has not been completely torn off in the first and second half layers, it is necessary to remove half of the dry film in the first layer again;
If you want to see a significant impact on a PCB board, you can use a deionization machine to grind the side of the semi dry film that has been torn off;
When signals are generated due to the volt-ampere characteristics between wires due to open circuits and short circuits generated by other components on the circuit board, open circuits are prone to occur. For the part of the circuit board with power supply, voltage and sound and light alarms can be generated due to both types of measures.
In the power supply section, attention should be paid not to connect undivided components to the output power supply with dedicated wires to avoid burning the components due to current output between the power supplies.
