Nowadays, many people like to assemble computers by themselves, but some circuit boards are relatively fragile and may be damaged if they are slightly bumped. However, some problems with the circuit board can be repaired, so when repairing the circuit board What tools do I need to prepare?

(1) circuit short circuit tracer: When performing circuit board repair work, we often encounter the phenomenon of short circuit in the power supply or other circuits. If we have a circuit short circuit tracer, we can easily find out the cause of the short circuit. .

(2) EPROM eraser: used to erase data in memory chips to facilitate reuse and save maintenance costs.

(3) signal generator : Circuit board maintenance work is generally not done at the equipment site. How to add signals to the input circuit of the circuit board? The signal generator is very important. You can use the signal generator to simulate the equipment during maintenance. The signal is added to the circuit board, and then the waveform of the output circuit is judged using oscilloscope , which can quickly determine the location of the fault.

(4) logic analyzer : used to detect the logic level of the logic device in the circuit board to determine the location of the fault.

(5) Constant temperature blowing soldering station , hot air gun : used to solder components on the circuit, especially integrated circuit devices, very easy to use.

(6) constant temperature electric soldering iron , rosin, solder wire : used to solder electronic components in circuit boards.

(7) Anti-static gloves : When performing circuit board repairs, sometimes the human body will generate static electricity, which can damage the integrated circuits in the circuit board. In order to prevent the components in the circuit board from being damaged by static electricity from the human body, you can wear anti-static gloves during maintenance operations. Static gloves can solve the problem of accidental damage to components due to static electricity.

hopes to be of some help to everyone.
