1、电路设计原理和工艺

电路原理的好坏分辨通常只能从专业角度着手。现阶段电源模块大体可分为课板和灌封两种，裸板可以根据直观的方式，如电子元器件的布局合理整齐有序、大方、有序、焊点亮净挺拔。而灌封式模块，就没法查看内部的情况，但是由于不外露，在安全性和性能指标层面要好很多。焊接工艺可包括手工焊接与波峰焊工艺，机械化生产的波峰焊工艺品质要优于手工焊接。

2、芯片的元器件

电源的核心就是IC，它犹如电源的大脑一样，IC的好坏直接影响着电源的各项参数。

3、变压器元器件

决定电源的功率、耐温等则是变压器。变压器负责完成交流电-直流电，能量超载就会饱和炸机

4、电解电容和陶瓷电容

电解电容，和独石胆电解电容，它采用硫酸做绝缘介质，可以将较大的容量做成较小的体积，并在上面标有+的符号，有的标有的符号，一般做低频交联和旁路滤波用，缺点是介子损耗大一些，独石电解电容，由于采用特殊的材料，性能优于普通电解频率特性较好，但容量不能做的太大，可用于精确地电路中，如振荡、或定时电路陶瓷电容有瓷介电容、瓷片电容、瓷管电容、陶瓷半可变电容几种。主要是无极性，介质材料较好，容量不能做的太大。适用高频电路。

1. Circuit design principle and process

The distinction between good and bad circuit principles can usually only be made from a professional perspective. At this stage, the power module can be roughly divided into two kinds of class board and potting, the bare board can be based on an intuitive way, such as the layout of electronic components is reasonable and orderly, generous, orderly, and the solder joint is bright and clean. The potting module can not see the internal situation, but because it is not exposed, it is much better at the level of security and performance indicators. Welding process can include manual welding and wave welding process, mechanized production of wave welding process quality is better than manual welding.

2, chip components

The core of the power supply is IC, it is like the brain of the power supply, the quality of the IC directly affects the parameters of the power supply.

3, transformer components

The transformer determines the power and temperature resistance of the power supply. The transformer is responsible for the completion of AC - DC, energy overload will saturate the machine

4, electrolytic capacitor and ceramic capacitor

Electrolytic capacitors, and monolith electrolytic capacitors, which use sulfuric acid as an insulating medium, can make a larger capacity into a smaller volume, and marked with a + symbol on the above, and some marked symbols, generally do low-frequency crosslinking and bypass filtering, the disadvantage is that the meson loss is larger, monolith electrolytic capacitors, due to the use of special materials, the performance is better than ordinary electrolytic frequency characteristics, However, the capacity can not be too large, can be used in precise circuits, such as oscillation, or timing circuit ceramic capacitors have ceramic dielectric capacity, porcelain capacitor, porcelain tube capacitor, ceramic semi-variable capacitor several. It is mainly non-polar, the medium material is better, and the capacity cannot be too large. Suitable for high frequency circuits.
