How to identify the pros and cons of circuit board substrates? When customers choose PCB board factories, most of them seldom design research on PCB board materials, and most of their dealings with board factories are simple communication of laminated process structures. The editor of Shenzhen Idea...
The question "How to read circuit boards" or "How to read schematics" often arises for beginners. Sometimes "What is this component" may also arise. These questions can be solved altogether in this article guiding how to read a circuit board and identify components. How to Read Circuit Boar...
Other than visual inspection, you can find various approaches to identify the main reasons for a circuit board short circuit. Testing of circuit boards components Using the Digital Multimeter You must examine the recognized resistance existing between the various circuit locations on the circuit board ...
Because there are many parts on the circuit board, if the welding is not good, the circuit board that the parts are easy to fall will seriously affect the welding quality of the circuit board. It is important to have a good appearance after welding and carefully identify a strong interface....
In most cases, X-ray images of an integrated circuit’s internal structure are enough to confirm or eliminate wire bond breaking as a failure mechanism. Acoustic microscopy can also gather data when wire bond fracture is a suspected failure mechanism. Because it can identify air gaps within a ...
This article has given full details regarding the entire well-known surface mount device – SMD components. We have explained how to identify these electronic components just from their appearance. However, if you have needs or concerns regarding the SMD components or printed circuit board, you can...
Because the circuit traces of the black PCB are difficult to identify, it will increase the difficulty of repairing and debugging in the R&D and after-sales stages. Generally, it is assumed that a brand without a deep RD (R&D) planner and a powerful repair team will not easily use a blac...
There are several ways to identify an SMD component. The first step is to look at the shape of your component and its size, which will help you determine if it's an IC or another type of component. If you're still unsure about what type of component you have, try looking at one si...
1.Determine solder points:Examine the circuit board carefully and identify the locations and quantities of the solder joints to be desoldered to proceed with the disassembly work. 2.Preheat the soldering iron:Preheat the soldering iron to the appropriate temperature, typically between 300°C and ...
As a last resort, physically take the PCB apart by removing components and re-running multimeter tests on the exposed pads. This may help identify the component or area that is causing the short circuit. Be aware that this is an extreme form of testing and should only be done as a last...
