Frequently Asked Questions circuit board repair

Q & A follows:

First, what kind of equipment you can repair circuit boards ?


    
Simply put, we are not subject to trade restrictions repair circuit boards , as long as the electronic control board , we all repair and maintenance without drawing the chip level .

Second, how do you detect no drawing board ?


    
First, we have the international advanced circuit board fault diagnosis instrument ; Second, we have experienced professional maintenance engineers , just to understand the purpose and Symptom board can be.


Third, what equipment you have repair circuit boards ?
         We have taken the circuit board has a lot of equipment , according to the industry, the medical industry has a variety of equipment circuit boards, circuit board industries a variety of equipment , civilian industry a variety of equipment circuit boards, of course, there are plenty of special industrial equipment repaired circuit board. For circuit boards especially imported equipment circuit boards, especially in our maintenance and more .
Some commonly used inverter, monitor, display, touch screen , power supply, etc. I often repair.

Fourth, some programs the chip board program lost how to do ?


    For the program the chip , such as EPROM, we have a dedicated reader can burn . However, the program needs to provide customers with a good chip , the presence of the first school down the computer, and then writes the new chip can be.
If similar problems occur again in the future , can be directly written .


Fifth, some of the circuit board part number are erased , how to detect ?


    Our equipment has a device recognition, for most devices can be directly identified.
You can also analyzed according to the principles of the circuit is a type that directly replaced.


Six , specific device how to detect ?


    Some special devices which model is named after the manufacturers themselves , may be an alias of a universal device that can identify through the instrument , the instrument will prompt substitution of several models .
Another possible use of the instrument has the compare function testing , but requires customers to provide a good board.


Seven, how to test analog chips ?


    
The first can be directly tested, can be compared to test the second and third experiments can be connected to the circuit , using an oscilloscope or multimeter test analysis .


Eight , failure to check out the device , you can buy it?


    We have a dedicated device suppliers , Beijing , Shenzhen , Hong Kong and abroad have , and also can be purchased online . Generally you can buy , but sometimes longer purchase of individual devices , there may not buy .
However, some devices can be replaced with the same function devices , you need to change the connection of the circuit, to achieve the same old results.


Nine, the board really knows how to fix it?


    A situation is detected by our instruments , to be sure repaired. Another situation requires the machine actual test.
And even machine experiment can be done by the user , can also be done in person by our engineers .


Ten, we do not have the ability to determine that a faulty board how to do ?


    
A telephone guidance by our engineers ;
    
2 may send engineers on-site inspection ( but need to charge the appropriate field testing fee )


XI, how to charge ?


    
When the board is based on the size , the ease of maintenance are charged to labor .


Twelve , given what charges ?
 

    
1 Press repairman difficulty with the maintenance fee ( per hours 200 yuan ) device count bill
    2 is a sub -scale integrated circuit boards , chips based on the number of large, medium and small scale, we will be quantified to the area to take charge. Based on our long-standing practice has proved that our maintenance customers only purchase price equal to the cost of the new board 20 --- 30% , has worked with companies we are quite satisfied , and indeed for businesses to save a lot of money.
So our fees are not high .


Thirteen , why only three months warranty , and repair parts only warranty ?


    Generally , under normal operating conditions the new device , for three months without failure, the device described in this standard may be of use, but the device may lead to other problems because of this board is damaged , maintenance problems are not , therefore , the other parts are not damaged
warranty.


XIV, the board how bad repair charges ?


    
The general situation is no charge , but there are exceptions.


Fifteen , if you paid for, but did not fix the board how to do ?


    The board did not return repaired first and then repair until repaired.
Second , due to various reasons do not fix it
We will work with you to have negotiated a refund.


Sixteen , the replacement cost of the device how to count ?


    Device costs will be charged the actual market price , no tax increases .
Low cost of the device will be negligible .
Part of the burden of routine repairs of our company , to buy expensive or special devices paid by the customer .
No less than 100 yuan fee , charge more than the original price of $ 100 .


Seventeen , repair the circuit board has a discount?


    First, the initial contact with the customer , in terms of time may give priority to enable our customers understand.
Second, long-term cooperation agreement signed customers , price concessions , time can advance.


Eighteen , how the size of your company ?


    My company has nearly a million test and maintenance equipment. Where: three large-scale comprehensive instrumentation , portable instrument a comparison , a dedicated short-circuit tester , a logic analyzer , two burner , rub the beginning is an oscilloscope four, a signal generator , several sets of various power and multimeter . The company's existing senior maintenance engineer six .
Is still actively recruiting senior technical personnel.


Nineteen , you engaged in maintenance work for many years?


    
We do repairs so far from the beginning of 1999 , has a number of enterprises, the maintenance of a large number of circuit boards , enterprises save a lot of money , by the enterprises of praise , to establish a good reputation .
