What should be paid attention to in PCB reverse engineering?

Let us check detailed instructions：
The first step:
The first point is the most important of all. Before doing PCB reverse engineering. Be sure to look carefully at the MCU chip on the PCB board. Is the chip locked? Does this encrypted chip currently support cracking? Are the PCB chips polished? Unknown component model evaluation.Therefore, you need to send high-definition PCB front and back pictures to us. Our company will provide professional technical evaluation, and it is free! At the same time, many projects can be one-stop solution for you: IC unlocking –PCB reverse engineering –PCB board –sample production!
Send PCB board to us:
Pay attention to packing PCB board when shipping, so as not to fall off components.
Start to work:
Our process of PCB board reverse engineering does not include the program reading of the chip. An additional charge is required to unlock the chip.
What about BOM :
Make BOM list: we will according to the physical PCB measurement data provided by the customer. However, there may be individual component models that are not accurate. Being polished or modified because of rarity or model. As a result, we cannot find the specific model. We will indicate the reference material in the BOM.
What is software support it?
The software we used for PCB reverse is Protel 99se. Can be used to modify the PCB file;
what about PCB reverse success rate?
We arrange four projects to complete each PCB board. Professional disassembly of components, PCB drawing, BOM production, reverse schematic engineering, and finally check to ensure that the data is 100% accurate.
What’s files can we got it?
PCB files, BOM list, SCH, Original products photos, scan pictures some customer want Gerber files…
