PCB manufacturer China tells you the Impedance problem handling:

1. Regarding the control parameters of impedance, the control requirements can be achieved through mutual adjustment in production.

2. After lamination in the production, the board is sliced ​​and analyzed. If the thickness of the medium is reduced, the line width can be reduced to meet the requirements; if the thickness is too thick, the copper can be thickened to reduce the impedance value.

3. In the test, if there is a lot of difference between the theory and the reality, the biggest possibility is that there is a problem with the engineering design and the test strip design.
