Such window is divided into 5 parts, and the test procedure at upper left corner, the test time at the upper right corner, the test stauts and result in the middle, the test statistical data at the lower left corner, and the accessory function at the lower right corner (as shown in Figure A-2-2-2-Fig01).Figure A-2-2-2-Fig011. Testing ProcedureIt displays the DUT Board name, test sequence, and total test steps. The test sequence includes four sections: open circuit test, short circuit test, IC open test, and parts test. It displays the test procedure set by the user, and the total number of the test steps includes the steps of testing all parts.Test Time StatisticsIt displays the number of tests, total test time, and test time for this time. In addtition, it also displays the skip, real, and fail steps.System Test Status and Test ResultThe test status is shown in the upper left section of this area, and mainly divided into:a. Ready to start testing: The system is ready. Press the TESTor RETEST button of the machine to perform the circuit board test .b. Failed Open Circuit: The open circuit test of the circuit boardis failed.c. Failed Short Circuit: The short circuit test of the circuit boardis failed.d. Failed Parts: The parts test of circuit board is failed.e.IC Parts Fail: The IC compontnet test is failed.f. Passed Item: The circuit board is passed.g. Operator Aborts Test.When the system test status is ready for testing, users may press the TEST button of the machine to perform the board test. The system test status will show the messages of the open ciriuit test, short circuit test, IC open test, and parts test according to the current test progress. If there is a fail in the testing procedure, the system test status will show the messages of failed open circuit, failed short circuit, failed IC Open, and failed parts according to the failed conditions.A complete circuit board test is divided into 5 sections: Discharge, Open, Short, IC Open, and Parts. If the test completes a certain section, then the corresponding light on the left side of this area will change color. The light was yellow, and green light indicates the normal procedure of the test and red light indicates the abnormal procedure of the test. The test result will be shown on the right side of the window, and the current test procecure is shown in the middle of the window.2. Test Data StatisticsIt displays the number of tests, number of passes, number of failed open circuits, number of failed short circuits, number of failed parts and their percentage for today. For each tested circuit board, the test statistical data will be computed and shown in this area.3. Accessory Functionsa. Testing Circuit Board (F5): When the pressing machine ispressed, we can perform the test directly.b. Stoping the Test (F6): Do not stop testing the board during thetest while the pressing machine is raised.c. Saving the Day Report (F1): The day report is saved into thehard disk. When user finishes with this system, the day report will be saved to the hard disk automatically.d. Printing Failed Component List (F12): The failed test reportis printed. When users sets at the <Edit> and <Test Parameter > not to automatically print the failed component list, the usermay press “F12” to print the failed component list after thetest.f. Printing the Day Report (F3): The day report is printed out.g.Displaying failed parts list (CTRL-F): After the test iscompleted, it shows the data of the failed parts. In thiswindow, you can set up the dipslay types: All, Component, ICDiode, IC Empty Solder, and high pressure.h. Editing the Test Data (F11): Entering the editor to edit thetest data.i. Displaying Failed Open/Short Circuit List (CTRL-O): Afterthe test is completed, it displays the failed open/short circuit data.j. Showing the Diagram of the Failed Parts Position (CTRL-R):The x-axis of the circuit board is divided into at most 8 rowsA-H, and the y-axis into 8 columns 1-8. The screen shows thecorresponding position of the failed components to facilitaterepair and maintenance. The number of rows and columns ofeach circuit board can be set up in <Edit> and <TestParameter>.k. Viewing the Diagram of the Componenet of the Circuit Board(CTRL-V): If the circuit board is tested to be failed, we canuse Board-View to quickly and conveniently locate the position of the failed component and reduce the time forlooking for the failed components. However, when using thisfunction, the CAD files such as PINS.ASC, NAILS.ASC, andFORMAT.ASC are needed. Users may use the followinginstruction to look for specified component and the test pinposition.If the user wants to exit the test, select <Exit> from the upperright section of the screen.A-2-2-3 Testing Control Box(As shown in Figure A-2-2-3-Fig01)1. VACUUM: If the VACUUM Light is on, it indicates VACUUMDOWN, and the fixture stand is either moving downward or thefixture stand has dropped on the Interface. If the VACUUM light is dimmed, it indicates VACUUM UP and the fixture stand is moving upward.2. HP/GR ADAPTOR: It will connect the interface of the fixtureand the interface of the adaptor.3. Press the TEST button to start testing (as shown in Figure A-2-2-4-Fig03).Figure A-2-2-4-Fig034. After the test is completed, lift the lid to remove the test baord(as shown in Figure A-2-2-4-Fig04).Figure A-2-2-4-Fig04Figure A-2-3-2-Fig012. Pull out the fixture in parallel (as shown A-2-3-2-Fig02).Figure A-2-3-2-Fig02A-2-4 Emergency Switch1. If there is a power failure, we should turn off the master power ofthe server. Turn the power on again when the power supply issteady.2. If there is abnormality on any system, press the emergency switchon the front left section of the instrument table and notice the related engineering staff. After the system emergency switch is pressed, the power required by the TR-8001 system will be turned off, but the power supply for the PC and monitor will continue.3. After the emergency switch is pressed, rotate the emergency switchthe pressing machine are pressed to perform the test, the statisitcal data of the test will be accumulated in the testing section. If both of the RETEST and DOWN bottons are pressed to perform the test, the statistical data of this test will be accumulated to the retest section. The difference between the two is to provide different statistical data for users. The DUT Board after repair can be used for retesting and distinguishing from general test. The last row has two numeric values representing the ratio of pass rates, having the significance as follows:PPY Yield Rate (First Time Test Yield Rate) = Number of Passed Items for the First Time/Total number of Tests for the First Time Passed Yield Rate = (Number of Passed Items for the First Time +Number of Retest Items)/Total Number of Tests for the First TimeThe statistical analysis of the above table is as follows:1. The number of DUT Boards for that day is 200 pieces, and thetest result shows there are 180 passed pieces (the rate is 90.0%),5 failed open circuit pieces (the rate is 2.5%), and 10 failedcomponent pieces (the rate is 5.0%).2. After the repair, retest the 20 pieces of original failed boardswherein 10 pieces are passed, 3 pieces are failed open circutit (rate is 15.0%), 2 pieces are short circuit (rate is 15.0%), and 5 pieces of failed components (rate is 25.0%).3. Therefore, the number of DUT Boards for that day is 220 pieces,wherein 190 pieces are passed item (rate is 86.4%), 8 pieces are open circuit boards (rate is 3.6%), 7 pieces of short circuit boards, (rate is 3.2%), and 15 pieces of failed components (rate is 6.8%).4. PPY Yield Rate = 180 / 200 = 90.0%Passed Yield Rate = (180+10) / 200 = 95.0%F2 U17 Pin 26Pin <642> ---> Component connected to test point 64228 E2 JP8-1-2 642 229 E2 JP9-1-2 642 2Pin <4> ---> Component connected to test point 41 A1 JFUSE 8 4440 A1 C6/C1 4 1Pin <5> ---> Component connected to test point 5394 A2 C18 5 1574 A1 L1 11 5Pin <11> ---> Component connected to test point 11208 A2 RN19-3-4 11 2574 A2 L1 11 5A3 U22 Pin 10A4 U34 Pin 27********** Component Fail *********1 R50_1 M_V:9999.99 Dev:+999.9% Test Step 1, Component R50_1,Real value 9999.99Deviated percentage +999.9%Act_V: 50.00 Std_V: 50.00 Loc: A1 Real component value 50.00Component standard value 50.00, Position A1 H-Pin:1 L-Pin:2 +LM:+8% -LM:-8% High test point is 1; low test point is 2.Upper limit of standard value is +8%Lower limit of standard value is -8%7 R100_1 M_V:9999.99 Dev:+999.9% Test Step 7, Component R100_1,Real value is 9999.99Deviated percentage +999.9%Act_V: 100.00 Std_V: 100.00 Loc: A1 Component real value 100.00Component Standard value 100.00, Position A1 H-Pin:4 L-Pin:5 +LM:+8% -LM:-8% High test point is 1; low test point is 2Upper limit of standard value is +8%Lower limit of standard value is -8%。
