What kind of supply will be more safe?(2)

1: The quality and resolution of circuit design principles and process circuit schematics are usually from a professional perspective. The power module can be divided into bare board and package board. In an intuitive way, the bare boards such as electronic components are arranged in a reasonable and orderly manner, and the cleaning pads are lit vertically. In addition, fixed modules will not be able to view the internal situation, but this is much better because the security and performance levels are not disclosed. The welding process can include wave welding and manual welding. In the mechanized production process of wave welding, the quality of wave welding is better than that of manual welding. 

A modular power supply is a power supply that can be directly mounted on a printed circuit board and can be used for application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field programmable gate arrays (FPGAs) and other Digital or analog loads provide power. Typically, such modules are referred to as load (POL) power supply systems or point-of-use power supply systems (PUPS). Due to the obvious advantages of the modular structure, modular power supplies are widely used in switching equipment, access equipment, mobile communications, microwave communications, optical transmission, routers and other communications fields, as well as automotive electronics, aerospace, etc.

2: The core problem of Marine boost power supply for chip modules is the integrated circuit, which is just like the brain of Marine boost power supply. The quality of integrated circuit directly affects the working parameters of supply.
