Description
Technical field
The utility model is specifically related to a kind of six layers of PCB copper thickness test modules, and the finished product especially suitable for six layers of PCB is surveyed
Examination.
Background technology
PCB (printed substrate) copper thickness has conclusive effect to impedance matching, and whether impedance matches and have influence on
The change of transmission and loss of signal of the data-signal on PCB, so monitoring copper thickness becomes important all the more.Confirm copper thickness most
Main method has two kinds：1) CMI test surfaces copper thickness 2) cutting into slices confirms that copper is thick in surface and through hole.CMI needs when testing
Measured object surface needs certain area, but need to monitor at present is that copper after etching is thick, and its complete copper face is relatively few,
It is more difficult during selection test zone.Section confirm need a small sample is cut from PCB, be then ground/polish again with up to
