We are often asked which schematic diagrams we use. In this blog we will tell you.
We use the Xin Zhi Zao, and we take this opportunity to tell you that we used to use the ZXW but we will tell you why we prefer the Xin Zhi Zao.
We use this schematic diagram for three main reasons: first of all, because it is very complete; it has as many schematic models as the ZXW. In fact, there are times when certain models were in the Xin Zhi Zao that the ZXW did not have. Of course, we must admit that it also happened the other way around, so while it is one of the reasons we have the Xin Zhi Zao, it is not one of the reasons we prefer it.
Here come our reasons for preference: because of the technical support material it has. They have repair cases and, above all, block diagrams and diagnostic protocols, called troubleshoot ways. These are super useful for effective board diagnosis and repair. When you study this section, you grow a lot as a technician.
Finally, for the costs: while the ZXW is about 50 euros per year, this software can be purchased from 8 euros per month to 180 euros for 20 years (9 euros per year); so seen this way, it can be almost free.
If you want to learn more about this fundamental facet of repairs, on our YouTube channel, we have videos in which we teach how to interpret schematic diagrams in a simple way and with supporting material.
For example, you can watch our video while we repair a Huawei P Smart and learn more about it:
