This test method covers measuring the dc magnetic field transmitted through a round ferromagnetic sputtering target ("pass through flux" or "PTF"). In this test method the source magnetic field is in the test target's radial direction.
Formerly under the jurisdiction of Committee F01 on Electronics, and Subcommittee F01.17 on Sputter Metallization, this test method was withdrawn in July 2007 in accordance with section 10.6.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
1.1 This test method covers measuring the dc magnetic field transmitted through a round ferromagnetic sputtering target ("pass through flux" or "PTF"). In this test method the source magnetic field is in the test target's radial direction.
1.2 Planar disk-shaped targets in the diameter range 5 to 8 in. inclusive (125 to 205 mm inclusive) and of thickness 0.1 to 0.5 in. inclusive (2.5 to 13 mm) may be characterized by this procedure.
1.3 This test method is also applicable to targets having an open center, for example, to targets 5-in. outside diameter by 2.5-in. inside diameter by 0.25-in. thick (127-mm outside diameter by 63.5-mm inside diameter by 6.35-mm thick).
1.4 Targets of various diameters and thicknesses are accommodated by suitable fixturing to align the piece under test with the source magnet mounted in the test fixture. Tooling, covering several popular target designs is specified in this procedure. Additional target configurations may be tested by providing special tooling. When special fixturing is used all parties concerned with the testing must agree to the test setup.
1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
