Thus, reference to specific features appearing in an embodiment does not indicate that those features are not present in the embodiments. The following description is intended to assist those skilled in the art to understand the invention. -11 - 201008787 Therefore, features that are commonplace in the art are not specifically described, as those skilled in the art are well aware of such features. BRIEF SUMMARY OF THE INVENTION Broadly speaking, the present invention relates to testing of a print head integrated circuit such as a printhead microchip or integrated circuit (1C) mounted on a carrier (not shown). The carrier typically includes a printing fluid φ distribution channel with a print fluid supply 1C, and a tape and tape automated bonding (TAB) electrical connection for 1C. The 1C receives the control signal from the printer controller of the appropriate printer via the TAB connection. In general, the present invention provides test apparatus and methods for electrical connection to 1C to ensure proper operation. In particular, the present invention includes a test device that is configured to operatively receive and hold such a carrier and perform an electrical test in 1C located thereon. The invention further includes a test station for a tester, a diagnostic probe assembly for such a tester, and a system for testing a carrier having an IC. A test φ method is also provided. These points are set forth below separately, but those skilled in the art will be able to understand the various aspects and/or overlaps between the components of the present invention. Test Apparatus Description Referring to Figure 1, an embodiment of a test apparatus or tester 10 of a printhead integrated circuit is illustrated. Tester 10 includes a housing 12 that defines a support assembly 17. The touch panel display computer 14 is covered in the housing 12 as shown and provides an interface to the operator of the tester 10. The tester in turn includes a controller 72 (as described below) and a holding assembly 16 for operating the carrier. A shifting assembly 1 9 is also provided to shift the test probe contact 18 of the test circuit that holds the carrier in the holding assembly 16 in contact with the tester. The controller 72 is programmed to process the test signals received from the integrated circuits of the carrier while the test circuit is performing electrical tests on the carrier. The test probe 18 of the test circuit is operatively coupled to the controller 72 and includes test signal generation and measurement circuitry for interoperating with the operative circuit of the integrated circuit being tested by φ. The adapter circuit is assembled to provide physical and electrical interfaces to the integrated circuitry on the carrier. These components are discussed in more detail below. The support assembly 17 is supported by the casing 12 and includes a table top assembly 23 that supports one of the holding assemblies 16. The holding assembly includes a test stand 2 1 that is displaceable into and out of the operating environment, wherein the print head 1C is coupled to the test circuit through the probe 18. When the test stand is not in the operating environment, the operator can insert or remove the carrier from the holding assembly 16. The retaining assembly 16 includes a clamp or retaining mechanism 117 (as described below) disposed on the test rig 21 to clamp the carrier into position prior to shifting the test rig 21 to the operating environment. Tester 10 in turn includes an operator control panel 22 that includes an activation button, a clamp button, a reset button 'and an emergency stop button. In one embodiment, the two outermost buttons are start buttons, both of which must be pressed simultaneously to activate the tester 10. This is a safety feature that prevents accidental starting of the tester 10. The reset button typically resets the tester 10, which ends any tests and moves the hold component 16 out of the operating environment to the loading position where the carrier can be loaded or not loaded with -13-201008787. The clamp button indicates the tester 10, and in particular the controller 72, to activate the clamp assembly 17 to clamp the carrier to the test station 21. The emergency stop button is another security feature that immediately shuts down the tester 10. The inventors have found that buttons made by Sprecher & Schuh are suitable for this application. It will be appreciated that the buttons of the operator control panel 22 and the touch panel 14 are configured to signally communicate with the controller 22 as described below. The controller is responsible for performing the actions indicated by the buttons or inputs received by the touch panel 14. The casing 12 in turn includes two pressure indicators 26 and 28. It should be understood that the tester 1 includes a pneumatic circuit for the shifting assembly 19 of the test stand 21 and the clamp assembly 1 1 7 . Thus, the pressure indicator 26 represents the pneumatic pressure of the jaw assembly 117 and the indicator 28 represents the pneumatic pressure of the displacement assembly 19. Tester 10 in turn includes a light curtain 20 security system controlled by the controller. The light curtain 20 allows the user to detect when a foreign object is approaching the test bed 21 during the test. When a foreign object is detected, the tester 1 is revoked to prevent damage. The chassis 12 further includes a computer interface 30, such as a USB socket, through which the controller can communicate with an external computer. Also provided is a barcode scanner 24 that is configured to scan bar codes from the various carriers under test to store test results for each test carrier. Controller Assembly Referring now to Figure 2 of the drawings, the upper rear enclosure of the casing 12 in the open position illustrates the upper portion of the tester 10. The enclosure covers some of the components of the control system managed by the controller. -14- 201008787 The flat PC 14, and the pressure indicators 26 and 28 are visible. The inventors have discovered that the Advantech PPC-123T integrated unit is suitable as a planar PC 14 of the present application.

The main functional components of the tester 1 are shown in a schematic representation. The Ethernet switch 44 forms a communication hub for engaging the various components of the tester 10 and the RMS 1 40 as shown. The tester 10 includes a PLC 72 having a related analog interface module 74 and a network module 70. The analog interface module 74 forms the interface between the PLC 72 and the solenoid valve 'these solenoid valves control the pneumatic components of the test stand 2 i and the shifting mechanism 19 of the -21 - 201008787, as described above. Network module 70 forms the network interface between PLC 72 and the other components indicated in FIG. The remote monitoring system or RMS 140 forms a local computing device with a communication link through the Ethernet switch 44 to the computing device or RMS 140. As described above, the tester 10 includes a diagnostic probe assembly 51 that includes a test circuit operatively coupled to the computing device or RMS 140 via a communication link of the Ethernet switch 44. The test circuit of component 51 is assembled to produce a φ bulk circuit test signal to test the print head integrated circuit. The adapter board 97 includes an adapter circuit operatively coupled to the test circuit on the controller board 50, and the adapter circuit is assembled to provide penetration through the probe 18 with the contactor 130 and the carrier The integrated circuit is an electrical and physical interface, as described above. Routing board 48 includes routing circuitry interposed between test circuitry on controller board 50 and adapter circuitry on adapter board 48 to route test signals to respective integrated circuitry on the carrier. The pneumatic test stand 21 and the lift mechanism 19 can be considered together as a processing mechanism 99 for holding and operating the carrier in which the integrated circuit is located. The PLC or controller 72 is operatively coupled to the mechanism, as described above, to control its operation. The PLC 72 is additionally connected to a communication device in the form of an Ethernet switch 44, managed by a computing device or RMS 140. It will be appreciated that the RMS or computing device 140 can be a PC having a graphical user interface for displaying the test results of the carrier printhead circuitry to an operator. Thus, the RMS or local communication device 140 is typically programmed to define a test server communication with the test circuit of the component 51 through the PLC 72. The RMS 1 40 performs remote monitoring of the tester. The bar code and test results of the respective carriers tested by the tester 10 are sent to the RMS 1 40 as quality and warranty control. The RMS 140 is in turn capable of communicating with the PLC 72 to provide operational parameters and instructions for controlling the tester. Method of Testing a Carrier II Figure 10 shows the possible method steps performed when testing the printhead integrated circuit on a carrier using the tester 10. It will be understood that reference to a reference number indicating a particular method step means the individual blocks indicated by the number in the figures. In terms of methods, the methods included in the present invention are not limited or limited to the specific methods referred to in this manner. Those skilled in the art will appreciate that other methods are possible under the invention that may remove some of these steps or include additional steps. In one embodiment, the method begins at block 160 where the operator prompts the PLC 72 to load the carrier into the test station 21 via the touch panel 14 (block 162). The PLC 72 in turn causes the operator to operate the clamp button on the control panel 22 (block 164). The operator can then load the carrier into test 21 (block 166) and depress the clamp button' to instruct PLC 72 to actuate jaw mechanism 117 to secure the carrier to fixture 124. Once the carrier has been clamped, the PLC 72 can activate the barcode scanner 24 to scan the carrier barcode (blocks 170 and 172, respectively). If the PLC 72 successfully scans the bar code, the bar code is stored and sent to the RMS 1 40, as described in -23-201008787. Then the PLC 72 enables the start button to operate, allowing the test of the carrier to continue. If there is a problem with the barcode, the PLC 72 displays an error message via the touch panel 14 and also notifies the RMS 140. As described below, no tests were performed on the carrier. It is indicated by blocks 174, 176, 178, and 180. Assuming the barcode is successfully scanned, the operator continues to depress the start button as described above (block 182). Then, the PLC 72 actuates the shifting mechanism 19 to lift the test stand 21 and the carrier firmly secured thereto to the probe 8 (block 1 8 4). The probe contacts the print head integrated circuit on the carrier so that testing can occur. Once the clamp of the test bench is in place (block 186), the PLC is ready (block 188) to perform the test routine (block 19A). In one embodiment, the test routine typically includes software instructions loaded by the PLC 72. The RMS 140 in turn supplies such test routine software to the PLC 72 via the communication link 44. The PLC 72 displays a message "Test will start" to the operator via the touch panel 14 (block 190). Once the test routine has been loaded by the PLC 72 φ, the beiJ PLC 72 displays a message "Test is in progress" to the operator via the touch panel 14 (block 192). The touch panel PC 14 typically executes a software command to display a graphical user interface (GUI) to the operator. Then, the PLC 72 executes the print head test routine (block 1 94) on the integrated circuit through the diagnostic component 51, as described above. The test routine includes a controller board 5 〇 generating a test signal to perform any or all of the following electrical test types: a hair Idd test, an Ipos test, a protective diode voltage critical test, a wire bond continuity test, and a Leakage test, a signal transmission -24- 201008787 In-voltage critical test, a signal output voltage test, and a functional test. When the different tests are completed, the touch panel 14 is given to the operator via the GUI. The PLC 72 stores the results (block 198) and sends the results to the RMS 140. When all tests are completed, the PLC is tested as shown in block 200. When the test is completed, the PLC 72 lowers the test station 21 to the loading position 202 that is not in contact with the probe 18, and releases the clamp (block 204) to enable removal of the GUI of the carrier touch panel 14. A message 196) may be displayed to complete the test, and the operator is prompted to load the next carrier (block 206). At the end of the test cycle (block 210) the carrier 208 is removed. The method steps are repeated for the next vector. Circuit Diagram Figures 1 through 1 4 are circuit diagrams of the above controller components.
