Embodiment Construction

[0022] The present invention will be further elaborated below with reference to the accompanying drawings.

[0023] The head tilt angle includes the head tilt angle (PSA, PitchofSliderAttitude) and the head tilt angle (RSA, RollofSliderAttitude). In theory, when the same HGA is at different assembly positions of the HSA, that is, at different heights, the test value of the head tilt angle is equal. That is, the test values ​​of PSA at different heights are equal, and the test values ​​of RSA at different heights are equal. Therefore, the idea of ​​the present invention is to use a HGA tooling to simulate Hook-up instead of HSA to carry the same HGA. The HGA tooling can realize two different heights. By performing PSA / RSA tests on the HGA at different heights, the test results can be obtained Multiple PSA / RSA test values ​​are compared to complete the precision analysis of the static mechanical parameter tester.

Abstract

The invention relates to a precision analyzing method for a static mechanical parameter tester and an HGA tool, wherein the precision analyzing method comprises the steps of fixing a magnetic head spring plate assembly on the HGA tool, wherein the HGA tool is provided with a bearing surface, a first positioning reference surface and a second positioning reference surface, the distance between the second positioning reference surface and the bearing surface is set as a first height, and the distance between the first positioning reference surface and the bearing surface is set as a second height; and when the magnetic head spring plate assembly is respectively arranged at the first height and the second height, performing precision analysis on the static mechanical parameter tester. The HGA tool comprises a body and a compression member. According to the precision analyzing method for the static mechanical parameter tester, magnetic head inclination angle testing is performed on the same magnetic head arm spring assembly at two different heights by means of the HGA tool of a transmission arm in the magnetic head arm assembly. Through comparing a difference between a first tested number and a second tested number which are respectively measured based on the first height and the second height, precision analysis on the static mechanical parameter tester is realized.

Description

technical field [0001] The invention relates to the field of static mechanical parameter testers, in particular to an accuracy analysis method and HGA tooling of a static mechanical parameter tester. Background technique [0002] At present, the static mechanical parameter tester is usually used in the industry to test the head arm assembly. The head arm assembly (HSA, HeadStack Assembly) is assembled from the transmission arm (Hook-up) and the head spring assembly (HGA, HeadGimbals Assembly). The mechanical parts that directly support the addressing and reading of the magnetic head, due to the particularity of their working performance, determine their high-precision requirements for combined assembly. However, the prior art is still unable to analyze the accuracy of the static mechanical parameter tester, so that the accuracy of the relevant parameters of the HSA product measured by it cannot be further guaranteed. Contents of the invention [0003] The purpose of the p...
