The following description is intended to assist those skilled in the art to understand the invention. -11 - 201009365 Therefore, the characteristics that are commonplace in the art are not specifically described, as those skilled in the art are quite aware of this feature. DETAILED DESCRIPTION OF THE INVENTION Broadly speaking, the present invention relates to the testing of a print head integrated circuit such as a print head microchip or an 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 1C. Test # method is also available. 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 the test apparatus or tester 10 of the print head integrated circuit is shown. Tester 10 includes a housing 12 that defines a support assembly 17. As shown, the touch panel display computer 14 is covered in the housing 12 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. The operator can insert or remove the carrier from the retention assembly 16 when the test station is not in the operating environment. The retaining assembly 16 includes a clamp or retaining mechanism 117 (as described below) disposed on the test station Φ 21 to clamp the carrier into position prior to shifting the test station 21 to the operating environment. The tester 1 further 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 1 〇, which ends any tests and moves the component 16 out of the operating environment to the loading position of the carrier that can be loaded or not loaded with -13- 201009365. 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 φ housing 12 in turn includes two pressure indicators 26 and 28.

The Ethernet switch 44 in turn provides an interface to the remote monitoring system as described below. The inventors have discovered that the Netgear FS605 Ethernet switch is suitable for this application. Controller board 50 and associated adapters, testers, and multiplexers (collectively referred to by reference numeral 48) are also visible. Controller board 50 and associated board 48 together form part of a diagnostic probe assembly, as described below. A wire slot 40 is also provided to facilitate the electrical and pneumatic connection of the components with a neat and easy access. ❹ Referring now to Figure 3 of the drawings, the lower rear enclosure of the casing 12 in the open position illustrates the lower portion of the tester 1 〇. Controller 72 is visible and is a programmable logic controller (PLC). The inventors have found that the Mitsubishi FX3U-16M PLC is suitable for this application. The PLC 72 can be programmed to control the different types of tester 1 。. The PLC 72 further includes a network communication module 70, which is a Mitsubishi FX3 U-ENET module that interfaces with the Ethernet switch 44.

The analog interface module 74 can be a Mitsubishi FX2N-4AD module. PLC 72 is also configured to communicate with controller board 50 and associated adapters, testers, and multiplexer boards 48. It should be understood that the PLC or controller 72 is responsible for the function and operation of the tester 10. All electrical and pneumatic components are under the control of the PLC 72. The enclosure of the casing 12 φ in turn includes a wire slot 60 to facilitate the connection of the electrical components with a neat and easy access. As shown, the assembly is mounted on rail 62. As shown, the enclosure, in turn, covers the mains power isolation switch 64 to isolate the mains AC power. The inventors have found that the Sprecher &amp; Schuh module number LE2- 1 2- 1 782 isolation exchanger is suitable for this application. Also included is a light curtain power supply 68 and associated light curtain safety relay φ 66. The inventors have found that the Keyence SL-U2 24V power supply and the Omron G7S-4A2B DC24 plug-in safety relay are suitable for this application. The residual current circuit breaker 78 is used for overcurrent and earth leakage protection, along with a safety relay 76 and a fuse 80 that provide additional overvoltage and associated power protection. The inventors have found that a Hager AD 810T circuit breaker in conjunction with an Omron G7S-4A2B relay and a Wieland SNO 4003K relay is suitable for this application. Figures 11 through 14 are circuit diagrams of some of the above components and their interconnections. -16- 201009365 Test Bench Figures 6 and 7 are embodiments of a retaining assembly 16 including a test station 21. This test stand 21 includes a retaining mechanism or clamp mechanism 117. The test stand 21 is mounted on the table top assembly 23 of the support structure 17 as described above. The test station 21 includes a fixture 124 that is shaped and sized to receive and position the carrier. In addition, a retaining mechanism or clamping mechanism 117 is provided on the fixture 124. The jaw mechanism 117 has φ at least one clamp assembly 1 1 8 for clamping the carrier to the test station 21. It will be appreciated that the controller 72 is responsible for controlling the operation of the jaw mechanism 117 through appropriate pneumatic components and circuitry, as described below. The fixture 124 includes a base member 123 and a locating tip 116 extending from the base member 123 to assist in positioning the carrier on the fixture 124. The positioning tip 116 is shaped and sized to be received in a pair of apertures defined by the carrier. The base member 123 is elongate, and the jaw mechanism 117 can include two opposing jaw assemblies 1 18 that are positioned on respective ends of the base member 123. Each of the jaw assemblies 118 includes a piston and cylinder arrangement 112 mounted to the base member 123; and a clamping plate 122 having a jaw finger pivotally mounted to the base member 123 for utilizing the piston and The cylinder configuration 112 is rotated into and out of a clamp position. As shown, the clamp plate 122 is mounted via a pivot tip 114. Each piston and cylinder configuration .112 includes an actuator coupling 120 and a button head cover 126 to assist actuation of the clamp configuration 1 12 through a pneumatic supply. The clamp assembly 1 1 8 in turn includes a pneumatic coupling 1 1 〇 for coupling the piston and the -17-201009365 cylinder configuration 1 1 2 to the pressurized gas supply to actuate the retaining assembly 16 . As noted above, a controller 72 in the form of a programmable logic controller (PLC) is configured to control the operation of the pressurized gas supply and the piston and cylinder configuration 112. The pneumatic components of the tester 10 are discussed in more detail below. Pneumatic Assembly Tester 10 features a general pneumatic assembly to assist PLC 72 to control assembly 16 and shifting mechanism 19. These pneumatic components include pressure indicators 26 and 28 as described above. Pneumatic components typically include a main supply regulator such as the SMC AR2000-02 regulator to control the entire pneumatic system pressure. Mechanical shut-off valves such as the SMC BM43 0-0 1 -00 three-turn mechanical valve are configured as mechanical shut-offs for pneumatic systems, including micro-mist separators to remove impurities and vent moisture from the pneumatic system of the tester 10. The inventors have found that the SMCAFD20-02-C module is suitable for this application. These components are linked to some built-in cartridge solenoid valves to control the shifting assembly 19 and the clamps 17 of the test station 21 as described above. These valves are controlled by PLC 72, such as the SMC SY3 160 solenoid valve, etc., which are 24V DC with 6mm pneumatic tube fittings. As described above, the test station 21 uses two single acting, single rod, spring-backed tip cylinders for the piston and cylinder configuration 112 to clamp the carrier to the test station 21. The shifting mechanism 19 uses the SMC MGPM series dual-acting small pilot cylinder to actuate the stage 21 into contact with the probe 18 of the 隅 test circuit. The shifting mechanism 19 typically includes two SMC D-Y7P universal automatic exchangers to indicate the travel limit of the displacement of the test station 21. In order to help the PLC 72 control the necessary pressure of the test bench 21 and the shifting assembly 19, it usually includes the s MC electronic pressure exchanger. The third exchanger can be further used to initiate the operation of the barcode scanner 24 when the stage 21 is lifted toward the probe 18. In fact, when the lift table 21 is activated by the table 21, such a third exchanger is activated. The inventors have discovered that the hand held product 3 800LR bar code scanner is suitable for the present application.

Also shown as the rod 9 8 and the test probe contact 〇 3 测试 ^ Test System Referring now to Figure 9, a system 100 for testing an integrated circuit using the tester 1 图示 is illustrated, as described above. Typically, system 100 packet 1 and remote monitoring system (RMS) 140 are as described above. System 100 includes a tester 10 that is configured to communicate with an RMS signal. One of the functional components of the tester 10 is illustrated in a schematic representation. The Ethernet switch 44 forms a communication hub that engages the various components of the tester 10 and RM S 1 40 as shown. &lt; Tester 1 includes a PLC 72 having associated analog interface module 74 and network 70. The analog interface module 74 forms the interface between the PLC 72 and the screw 'These solenoid valves control the test bench 2 1's pneumatic adapter into the insertion and the body circuit routing with the 的 path of the probe, then the positioning tip [8] The derivation has a push head including test 140 to some of its main use for the road module spool valve assembly and the 21 - 201009365 shift mechanism 1 9, as described above. The network module 70 forms the network interface between the PLC 72 and the other components indicated in Figure 9. The remote monitoring system or RMS 140 forms a local computing device with communication through the Ethernet switch 44 to the computing device or RMS 140. link. As described above, the tester 10 includes a diagnostic probe assembly 513 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 a product through the probe 18 with the contactor 130 and the carrier. The body 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 2 1 and the shifter φ 1 9 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 1 40. 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 140 performs remote monitoring of the tester. The bar code and test results of the various 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 10. Method of Testing a Carrier φ 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 The clamp button on control panel 22 is operable (block 164). The operator can then load the carrier into the test 21 (block 166) and depress the clamp button to instruct the PLC 72 to actuate the clamp mechanism 117 to secure the carrier to the 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 140 as described in -23-201009365. Then, the PLC 72 enables the start button to operate 'to allow the test of the carrier to continue. If the barcode has a problem, the PLC 72 displays an error message via the touch panel 14 and also notifies the RMS 140. As described below, the test was not 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). The PLC 72 then actuates the shifting mechanism 19 to lift the test stand 21 and the carrier secured thereto to the probe 18 (block 184). 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 execute the test routine (block 190). 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 begin" to the operator via the touch panel 14 (block 190). Once the test routine has been loaded by the PLC 72 Φ, the 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. PLC 72 then performs a printhead test routine on block circuit via diagnostic component 51 (block 194), as described above. The test routine includes the controller board 50 generating test signals 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, a drain Flow test, - signal transmission -24 - 201009365 Into the voltage critical test, a signal output voltage test, and a functional vector test. When the different tests are completed, the touch panel 14 displays the results to the operator via the GUI. The PLC 72 stores the results (block 198) and is also able to send the results to the RMS 140. When all tests are completed, the PLC stops testing as shown in block 200. When the test is completed, the PLC 72 lowers the test station 21 to a loading position that is not in contact with the probe 18 with the clamp 1 17 (block 0 202), and releases the clamp (block 204) to enable removal of the carrier. The GUI of touch panel 14 in turn displays the message to complete the test (block 196) and prompts the operator to load the next carrier (block 206). The operator removes the carrier (block 208) at the end of the test cycle (block 210). The method steps are repeated for the next vector.
