Before preparing to do circuit board repair operations, you should prepare some things and appearances to help repairers better carry out circuit board repair operations, according to our circuit board repair training center for many years of experience, prepare some necessary circuit board repair things and appearance, can achieve twice the result with half the effort, sharpen the knife without mistake the role of woodcutters. The things and appearance that you should have when performing a circuit board repair are summarized below.
(1) circuit board online repair tester: circuit board repair tester can detect the function and quality of each digital series integrated circuit and imitation integrated circuit online, it is a relatively easy to use high-end repair instrument, but the price is expensive, the price ranges from tens of thousands of yuan to hundreds of thousands of yuan, the cheap can not detect the quality of the imitation integrated circuit, and the expensive one has the function of imitating the quality of the integrated circuit. It is recognized as the most professional repair instrument in the circuit board repair industry in all countries around the world. It brings great convenience to repair. In China, there are many applications of Huineng electronic circuit fault online repair tester produced by Beijing Tianhui Weice Electronics Co., Ltd., the quality is also good, and the function is also more.
(2) Oscilloscope: It can detect the input and output waveforms of the critical points in the circuit board, and accurately identify the parts that cause problems according to the detected waveforms.
(3) Various programmers: the programmer can read out the data in the memory chip when repairing the circuit board, which is convenient for the repair personnel to backup, and can burn the read data into the blank memory chip for backup when the memory chip is faulty.
(4) (digital/pointer) multimeter: multimeter is the most cheap and practical repair appearance, the price is between tens of yuan and thousands of yuan, can detect the quality of each component in the circuit board, but also can detect the voltage and current data of the critical points in the circuit board.
(5) Circuit short circuit tracker: When carrying out circuit board repair operations, it is often encountered that the power supply or other circuits are short-circuited, and if there is a circuit short-circuit tracking, it is very convenient to find out the cause of the short circuit.
(6) EPROM eraser: used to erase the data in the memory chip to facilitate reuse and save repair costs.
(7) signal generator: circuit board repair work is generally not in the equipment site, how to add a signal to the input circuit of the circuit board, the signal generator is very important, the signal generator can be used to imitate the signal in the equipment to add to the circuit board during repair, and then use the oscilloscope to determine the waveform of the output circuit, which can quickly identify the part of the fault.
(8) Logic analyzer: used to detect the logic level of the logic equipment in the circuit board to identify the part of the problem.
(9) Constant temperature blowing and soldering station, hot air gun: used to solder the components on the circuit, especially the integrated circuit equipment, which is very easy to use.
(10) Constant temperature electric soldering iron, rosin, solder wire: used to solder electronic components in the circuit board.
(11) Anti-static gloves: when repairing the circuit board, sometimes the collar will produce static electricity, damage the integrated circuit in the circuit board, in order to prevent the components in the circuit board from being damaged by human static electricity, you can wear anti-static gloves during the repair operation, you can deal with the situation of accidental damage to the components due to static electricity.
(12) IC puller: used to pick up the IC plugged into the IC socket in the circuit board.
(13) Bridge tester, capacitance meter, inductance meter, etc
(14) Small things such as needle-nose pliers, diagonal pliers, tweezers, wall clock batches, etc.
After all, when engaged in circuit board repair operations, it is necessary to prepare a relatively easy to use instrument appearance and common things to achieve the purpose of quickly repairing the circuit board.
