Oxford Hole Copper Thickness Gauge CMI511 (CMI500)

I.               Product Application:

This instrument is suitable for non-destructive and accurate measurement of copper thickness before and after etching of printed circuit boards.

 

II.            Product Features:

1.     Automatic temperature compensation allows for immediate inspection of the board after it has been lifted from the plating bath. Thereby reducing waste and rework costs.

2.     The unique design allows the CMI500 Thickness Gauge to measure double or multi-layer boards and even penetrate tin and tin/lead layers for measurement

3.     Handheld design, battery powered

4.     One thousandth inch/micron unit conversion

5.     Serial output port for transferring results to a printer or OICM unique statistics and report generator

 

III.         Work Principle

Eddy current method is used to achieve accurate measurement of copper thickness in the perforation without destroying the sample

 

IV.          Main Function:

1.     Measuring function: measuring the coating thickness in the hole

2.     Application process: before and after PCB erosion process" class="taglink" href="http://www.kingrayland.com/index.php?ac=search&at=taglist&tagkey=erosion+process" target="_blank">erosion process" class="taglink" href="http://www.kingrayland.com/index.php?ac=search&at=taglist&tagkey=erosion+process" target="_blank">erosion process

3.     Software function: can record data online or do SPC analysis. (optional)
