This article is about the printed circuit board.In addition, the failure assessment of the printed circuit board was discussed.Resources: modern printed circuit boards consist of complex circuits, which is why there is always room for defects and errors.
In this write-We discussed the method of detecting defects.Complex electronics have long relied on integrated circuits on the pcb.Nevertheless, many improvements have been made in technology and the basic situation has not changed.
The pressure to package more circuits in smaller areas increases the density of these boards, and with this design, different errors occur.What\'s more complicated is to make sure that new defects occur, and the tiny size of the chip makes it difficult for them to be detected.PCB fault analysis handles the detection of these defects.
Over time, many methods have either appeared or have been customized to detect errors in varying degrees of detail and opinion.In this write-Finally, we found some defects on the printed circuit board and the methods to detect them.In general, we can name three major defects that affect the printed circuit board.
Defects related to material defects, defects with defects in electrical connections and defects in physical collapse.The specifications of printed circuit board materials are accurate.Semiconductors need to have precise specifications so that they have precise design features.
When the tracking resource exceeds the threshold, the printed circuit board will not be able to work as specified.Finding out if it is made up of trace material is the job of fault analysis.Electrical problems can be very common due to the complexity of the circuit.
However, it is often difficult to separate these defects.In addition, physical failures such as rust and fractures are also common.There are many kinds of cracks such as fatigue crack, fragile crack and ecological pressure crack.
Figuring it out helps us solve the root problem that causes the defect is of course the last goal of this work.In order to deal with various defects, a large number of fault detection methods have been written.Trace components were discovered by spectral techniques;micro-Identify tiny traces of heat using thermal images.
Many kinds of penetration tests are used to detect physical errors in matter.There are many detection methods, each with its own advantages and disadvantages.Sometimes, many different tests are essential to obtain a full picture of the beam\'s disappearance.
What kind of testing the company needs, and the budget, will be added to decide which one to hire
