It is easy to get damaged in the use of such parts as aluminum substrate, so how should we repair the aluminum substrate?

1. Firstly, we should observe the plate card of the aluminum substrate, understand the input and export of the card, and what the functions are.

2. After observing the board card, we will test the aluminum substrate line and perform the preliminary testing of the board card, which can eliminate the large range of faults by testing.

3. Then check the aluminum substrate components, find out the faults and deal with them through these tests, including line repair, component replacement, modification and other work.

4. Finally, after completing the maintenance work, test the line again, and make sure that the aluminum base plate has no failure, and carry out the machine test.
