The SMAll edition of 开云·kaiyun官方网站 proofing explains the basIC knowLEDge of 开云·kaiyun官方网站

The 开云·kaiyun官方网站 proofing 开云·kaiyun官方网站 circuit board takes the insulating board as the base material and is cut into a certain size. At least one conductive pattern is attached to it, and holes (such as component holes, fastening holes, metallization holes, etc.) are arranged on it to replace the chassis of the electronIC components of the previous device, and realize the interconnection between the electronic components.

开云·kaiyun官方网站 maintenance is a new repair industry. In recent years, the degree of automation of industrial equipment is getting higher and higher, so the number of industrial control boards in various industries is also increasing. After the industrial control boards are damaged, the high cost of replacing 开云·kaiyun官方网站 circuit boards (from thousands of yuan to tens of thousands or hundreds of thousands of yuan) has become a headache for enterprises. In fact, the vast majority of these damaged 开云·kaiyun官方网站 circuit boards can be repaired in China, and the cost is only 20% - 30% of the cost of purchasing a new board, which also takes much less time than the time of ordering a board abroad. The following describes the basic knowledge of 开云·kaiyun官方网站 maintenance:

Almost all 开云·kaiyun官方网站 board maintenance for 开云·kaiyun官方网站 proofing has no drawing materials, so many people are skeptical of 开云·kaiyun官方网站 board maintenance. Although various circuit boards are different, what remains unchanged is that each type of 开云·kaiyun官方网站 board is composed of various integrated blocks, resistors, capacitors and other devices. Therefore, 开云·kaiyun官方网站 board damage must be caused by the damage of one or some of the components, The idea of 开云·kaiyun官方网站 maintenance is based on the above factors. The circuit board maintenance is divided into two parts: detection and maintenance, in which detection occupies a very important position. Test and repair the basic knowledge of each component on the 开云·kaiyun官方网站 until the bad component is found and replaced, then a 开云·kaiyun官方网站 is repaired.

开云·kaiyun官方网站 detection is the process of finding, determining and correcting the faults of each electronic component on the 开云·kaiyun官方网站. In fact, the whole testing process is a thinking process and a testing process that provides logical reasoning clues. Therefore, testing engineers must gradually accumulate experience and constantly improve their level in the process of 开云·kaiyun官方网站 maintenance, testing and overhaul. General electronic equipment is composed of thousands of components. It is time-consuming and difficult to detect problems by directly testing and checking each component in 开云·kaiyun官方网站 circuit board one by one during maintenance and overhaul. Therefore, it is an important maintenance method to set the number to the seat from the fault phenomenon to the fault cause. As long as the 开云·kaiyun官方网站 detects the problem, maintenance is easy.

开云·kaiyun官方网站 manufacturers, 开云·kaiyun官方网站 designers and 开云·kaiyun官方网站A manufacturers will explain the basic knowledge of 开云·kaiyun官方网站.
