in normal operation of an electronic test machine a test plate will index from test head to test head . at each test head an electrical measurement will be made . it has been discovered that by dividing the index into a plurality of microsteps an electronic component can be swept underneath a test contact to evaluate the location of a test contact . in one example , the location of the electronic component may be measured relative to a fixed position on the test machine . this fixed position may be at least one blow off hole positioned on a base plate of the test machine . other fixed locations may be utilized as well . the fixed position may be correlated against the position of a motor driving the test plate to provide a centerline . in the case of a test plate that includes electronic components drawn into component pockets by a vacuum , this fixed position on the machine could possibly become offset relative to the test plate as the test plate becomes loaded with components . in such a case , both a loaded and an unloaded centerline may be provided . for each microstep a determination may be made whether an electrical connection exists between the electronic component and the test contact . based on the positioning of the plurality of electrical measurements relative to either centerline conclusions may be drawn with respect to alignment . the data derived from the measurements may be graphically presented to a user such that the user can draw conclusions with regard to alignment , or the system may evaluate the data and inform the user whether adjustments are necessary and if so what those adjustments are . with reference to fig1 there is shown a flow chart illustrating the acts of the method of the present invention . with reference to act 31 a test mode is enabled . at act 31 sample components are loaded into test plate 12 . at the test act 31 a motion controller 17 divides each index into a plurality of microsteps . these microsteps may be defined by motor steps of a stepper motor and may be of an arbitrary distance . in one example where the test plate includes eight concentric rings of 200 holes , an index may be approximately 1 . 8 degrees . in this example , the index of 1 . 8 degrees may be divided into 200 microsteps , thus enabling the test plate to advance 0 . 009 degrees for each microstep . as a rule of thumb it has been discovered that dividing the microsteps into a distance approximating 1 / 20 of the width of the component being tested provides useful results . however , the microstep may be a larger or smaller fraction of the index size . at act 33 the test plate is advanced by the above described microstep amounts . at act 34 the alignment system attempts to measure the electronic connection between a test contact 20 and the electronic component for each microstep . in one example the measurement is merely binary , meaning the system determines , yes or no , whether a connection has been made . in act 36 the alignment of the test contact is determined . the alignment may be determined either automatically or with reference to a graphic representation of data . with reference to fig2 a test machine 10 further includes controller 19 configured to receive the data from act 34 and either graphically presents it , as in fig4 , or makes other calculations . controller 19 may be part of an overall controller for machine 10 or may be a separate controller . with reference to fig4 there is shown a graphical representation of the output of a microstep evaluation of the alignment of the plurality test contacts . in the illustrative example of fig4 there is shown the evaluation of nine different contact heads , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , and 48 . each contact head includes a plurality of contacts , e . g . 50 , 51 , 52 , 53 , 54 , 55 , 56 , and 57 which have each been individually evaluated . another example of an evaluation an individual head is seen at 58 . the vertical bar referenced as 58 represents a plurality of successful microstep connections between points a and b . individual contacts may be evaluated to determine whether the connection between the test contact and the electronic component is consistent . with reference to head 59 there is shown a collection of microstep connections where for a portion of the microsteps e . g . 60 where no electrical connection could be made between the test contacts and the electronic component . this illustration would inform the operator that there was intermittent contact between the test contact at 59 and its associated component . an operator may remedy this in a variety of ways including replacement of the test contact at 59 . fig4 further illustrates an unloaded nominal center indicator line 70 . unloaded nominal center indicator line 70 references the positional centerline of the component pocket when the test plate is moving and unloaded . the measurement is made from a fixed position on the machine when the test plate is unloaded and moving . one example of determining a centerline is shown in fig3 . in particular when the test plate is moving a pair of blow off holes 23 may be observed and positionally correlated against a motor count location . in the example of fig4 the number of motor counts per angle of rotation of the test plate may be determined . the component pockets 21 center themselves over the blow off holes 23 at a repeatable motor count . in the example of fig4 this repeatable motor count is arbitrarily set at a zero motor count when the test plate is rotating and empty , as noted by reference numeral 70 . it has been observed that in operation of certain electronic component testing machines , such as the model 3430 as sold by electro scientific industries , inc ., the assignee of the instant application , a dynamic shift offset from the centerline occurs as the test plate is loaded with electronic components . that is , the rows of component pockets center themselves over the blow off holes 23 at a slightly different motor count when loaded . one cause of this dynamic shift is the vacuum utilized to retain the electronic component pockets . in the example of fig4 the dynamic shift was measured as approximately 15 positive motor counts . thus , in some examples a dynamic centerline 71 may be provided . an upper connect limit 72 and a lower contact limit line 73 may also be provided . in the example of fig4 the upper contact and lower contact limit lines provide suggestive limits where the test components within which component pockets 21 should be found . in the example of fig4 a connection between the electronic component and the test contacts is expected to occur between a positive 30 motor counts to a minus 15 motor counts . with reference again to fig1 , act 37 queries as to whether the test heads are aligned . if the test heads are not aligned , the test heads may be aligned at act 38 . act 38 involves adjusting the test contacts and / or test head such that they would be properly aligned with the test component received in the component pocket 21 in the test plate 12 . with reference to the example of fig4 one way to make this adjustment would be as follows . looking to the microstep measurements taken at 48 it can be seen that the measurements are biased in a leading direction . at least some of the microstep measurements in the example did not achieve a connection at the dynamic centerline 71 . thus an adjustment may be made to shift the test head in the direction of arrow “ c ”. with reference to fig5 there is shown a simplified test head 18 including a plurality of test contacts 20 . test head 18 is illustrated with reference to a test plate 12 and component pockets 21 . as is illustrated in fig5 test head 18 may include adjustments for y skew 75 , a y adjustment 77 and a theta adjustment 79 . movement of the aforementioned adjustments in the example of fig5 will move test head 18 in the y skew direction 76 , the y direction 78 and the theta direction 80 . in the context of measuring connections at act 34 of fig1 , the resulting data may inform a user of adjustments to a test head 18 to improve the alignment of the test head relative to the connect pockets . in the example of fig4 alignment information is graphically displayed to a user who may then interpret the data and adjust the test head . in an alternate example the measurement data may be mathematically interpreted and a user may be specifically informed of the adjustment to bring the test head into alignment . for example , this adjustment may inform the user to turn the theta adjustment one turn clockwise . as shown with respect to head 48 in fig4 the measurement results are preferably in a tapered pattern . this tapered pattern is a function of test plate 12 being circular . it is understood that a non - circular test plate may not yield a tapered pattern of measurement results . the y skew adjustment 75 affects the taper of the measurements . with reference to fig6 there are shown example profile patterns where the taper is skewed and y skew adjustment may be advisable . in the example 82 the y skew is correct for a circular test plate . in the example of 84 y skew is clockwise oriented and needs to be adjusted counter clockwise . in the example of 86 y skew is counter clockwise oriented and needs to be adjusted clockwise . with reference again to the example of fig1 , after an adjustment has been made , act 32 may be reinitiated to confirm alignment . reinitiating act 32 may not be necessary and may depend on customer preferences . if the query at act 37 indicates alignment , either determined automatically or by reference to a graphic illustration , the process is complete at act 39 . while the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment , it is to be understood that the invention is not to be limited to the disclosed embodiments but , on the contrary , is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims , which scope is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures as is permitted under the law .
