In-depth knowledge of industrial circuit board maintenance techniques: wang wenzheng wrote and published the following: chapter i electronic component awareness it's new, it's good, it's good, it's good, it's good, it's good, it's good, it's good. From experience, emphasis has been placed on practicality, and the reader's self-search process has been avoided; chapter iii. Typical circuit analysis provides a detailed analysis of the various types of circuits in the industry from the point of view of maintenance. Readers who encounter the same type of circuits in maintenance practice are able to do so in a single reverse way, not to panic, but to repair it; chapter 4 maintenance methods and techniques summarize some of the regular methods and techniques, condensed much of the author's experience and effort, practicality being tested through extensive maintenance practices, which can be used by readers and guided; chapter 5 maintenance examples are illustrated and a large number of examples of industrial circuit board maintenance are given, with the truth on the map, and beginners are allowed to paint a picture, make a sample of it, see how it works, and enjoy success.
