Surface Cooper SRP-4 Probe Tips 

SRP-4 tips for Oxford SRP-4-surface copper probe (CMI700/CMI600/CMI563/ Special) SRP-4 surface copper probe(probe tips) test technical parameters Dedicated to Oxford CMI760(CMI700) bench hole surface copper thickness gauge Accuracy: 5%, reference standard film Accuracy: Chemical copper: standard deviation 0.2%, electroplating copper: standard deviation 0.3% resolution: 0.1μm≥10μm, 0.01μm<10μm, 0.001μm<1μm, 0.01mils≥1 mil, 0.001mils<1mil Thickness measurement range: Chemical copper: 0.25μm - 12.7μm (10μin - 500μin) Electroplated copper: 2.5μm - 254μm (0.1mil - 10mil) Linear copper wire width range: 203μm - 7620μm (8mil - 300mil) Working characteristics: The application of advanced micro resistance testing technology. The tethered probe consists of four probes, AB being positive and CD being negative; When measuring, the current will have a small resistance from the positive electrode to the negative electrode, and the surface copper thickness is accurately and reliably obtain…
