PHASCOPE PMP10 - FISCHER - #2

Text version of the page

® By using the phase position of the probe signal instead of the amplitude for the coating thickness computation, the inter - fering influences of the specimen shape and of the probe lift-off are significantly reduced. This is illustrated in the figure to the right. 2000 1000 -1000 -2000 -3000 -4000 500 1000 1500 2000 2500 3000 3500 4000 50 25 8.6 344 4.3 25 12 0 0 Phase angle is a measure of the Zn thickness Lift-off [ m] Impedance plane of the probe (Zn/Fe) Reactance (imaginary axis) Resistance (real axis) Zn[ m] increasing Znthickness PMP10 with borehole calibration boards, probe ESL080B and printer. Copper cladding thickness measurement in boreholes using the probe ESL080V. Measurements on rough surfaces (top image: Zn/Fe with EDS20Zn) or NF coatings on NF base (bottom image: Cu/brass). Probe ESD2.4 is particularly well suited for small parts, because a calibration with adjustment to the measuring spot geometry is typically not required. Measurement Method The PHASCOPE® PMP10 utilizes the phase-sensitive eddy-current method according to the standard ISO 21968. Compared to conventional eddy-current method according to ISO 2360, this measuring method has signi ficant advantages for the thickness mea s - urement of metallic surface coatings. Copper Coating Measurements For PC-Board Production Available probes: • ESL080B and ESL080V for Cu thickness measurements in PC-board boreholes in a range from 5 – 100 ìm (0.2 – 4 mils). • ESD20Cu for surface copper thickness measurements on PC-boards. 1 – 100 ìm (0.04 – 4 mils) at 240 kHz 1 – 270 ìm (0.04 – 10.8 mils) at 60 kHz Measurement of Non-Ferrous Metal Coatings on Steel, NF or Iso Substrate Materials The following probes are available: • ESD20Cu for the measurement of nonferrous metal (NF) coatings of Cu, Al, brass, etc. on electr. non-conducting (Iso) substrate materials. • ESD20Zn for NF coatings on steel or iron, in particular with rough surfaces, or for NF coatings with a high electr. conductivity on NF substrate materials with a low conductivity, e.g., Cu/brass. • ESD20Ni for Ni/Fe 1 – 50 ìm (0.04 – 2 mils) at 240 kHz 2 – 100 ìm (0.08 – 4 mils) at 60 kHz • ESD2.4 for Zn/Fe on small parts Methods and Applications 992-017 02/09 02-09 Helmut Fischer GmbH Institut für Elektronik und Messtechnik, 71069 Sindelfingen, Germany, Tel. +49 (0) 70 31 / 3 03 - 0, mail@helmut-fischer.de Fischer Instrumentation (G.B.)
