Embodiment Construction

[0022] see briefly Figure 6B , Figure 6C and Figure 7 , the electronic testing machine 10 has at least one upper contact 14 and at least one lower contact 15 of the test module 12 . Each test module 12 may lie on angularly spaced radial lines extending from the associated central axis and have opposing pairs of contacts 14, 15 for testing electronic components. The production test plate or disc 20 may include a plurality of pockets 54 (by figure 1 shown in the examples section). Each pocket 54 carries an electronic component 32 to a test location 28 to be electrically inserted between the upper contacts 14 and lower contacts 15 of the test module 12 in order to perform one or more tests on the electronic component 32 . The test board 20 is rotatable about its central axis to transfer the electronic assemblies 32 to and from the test locations 28 that are in contact with the corresponding upper contacts 14 and lower contacts of the different test modules 12 15 associate...

Abstract

A compensation tool and process is provided for calibrating each test position located at a plurality of test modules of an electronic testing machine to a standardized value. Each test module is located on an angularly spaced radial line extending from an associated central axis and has a plurality of contacts for testing electronic components. The compensation tool includes a body having an axis of rotation coaxially alignable with the central axis for rotation to different angular positions, and a component-support member operably associated with the body for indexing movement to selectively align with different contacts associated with each test position. The component-support member includes a pocket for receiving an electronic component with terminated ends extending outwardly to allow electrical contact and testing at each test position.

Description

technical field [0001] The present invention relates to a device and a method for calibrating an electronic testing machine, such as a multilayer ceramic capacitor (MLCC), comprising at least one test module having a plurality of contacts for testing electronic components, to standardized values. Background technique [0002] It is generally known to provide multilayer ceramic capacitors (MLCCs) of known value that can be manually placed in specific test wells of a test board and electrically tested at a single contact station. The capacitor is then cycled through the other test stations, off the test board, recovered, and placed in place of the next test station. This process is repeated until the value of the capacitor has been recorded for each test bench. This current process for standard compensation causes some mechanical wear to the terminating end of the MLCC as the part is moved across multiple contacts, off the test board, recovered, and the process repeated. Due...
