Today author from qihe smt pick and place machine,chip mounter sharing you with some tips about how to detect circuit board component failure .<\/p>\n\n\n\n

\"<\/figure>\n\n\n\n

Most components that fail on a board are single failures of many components. Yishunde Electric has some methods here:<\/p>\n\n\n\n

Query:<\/h3>\n\n\n\n

The research method is to trigger the fault of the electronic circuit through the human body. This is the most simple and most safe method, and it is also the first step in the normal viewing process of various instruments and equipment.<\/p>\n\n\n\n

Measurement method:<\/h3>\n\n\n\n

The measurement method is the most widely used and most useful method in defect detection. According to the characteristics of electrical parameters, it can be divided into resistance method, voltage method, current method, logic situation method and waveform method.<\/p>\n\n\n\n

Tracking method:<\/h3>\n\n\n\n

Signal transmission circuits, including signal collection (signal seizure), signal processing (signal expansion, conversion, filtering, isolation, etc.) and signal function circuits, occupy a large share in modern electronic circuits. The key to checking this circuit is to track the transmission link of the signal.<\/p>\n\n\n\n

Instead of:<\/h3>\n\n\n\n

Substitution is a method of examining normal components, circuits, or components that have the same standard function, rather than those in the circuit that are suspect, and then distinguish the defective address. It is also one of the most commonly used and most useful methods in circuit debugging and correction.<\/p>\n\n\n\n

Compare:<\/h3>\n\n\n\n

Sometimes it is impossible to determine the location of the defect by means of various surveys and experiments, but the method of comparison, the method of comparison without confusion, can surprise people.<\/p>\n\n\n\n

Computer intelligent automatic viewing:<\/h3>\n\n\n\n

The use of powerful computer data processing capabilities and modern sensor technology can make circuit viewing more vivid and intelligent. At that time, various computers and computer equipment were used more widely and at a higher level. There are many circuit board elements and components that make up the downside. Choosing useful viewing options can save time and effort.<\/p>\n\n\n\n

If there is some inappropriate content or suggestion .I hope you can leave a reply to tell me and communicate with each other.
you can choose a reflow oven to meets your need like qfr630,qrf835,qrf1235
stencil printer model qh3040,qp3250,qfa5060
Also we have different kinds of smt pick and place machine like tvm802a,tvm802b,tvm802ax,tvm802bx,tvm925s,tvm926s,ql41,qm61,qm62,qm81,qm10<\/p>\n\n\n
