Install tool plate or support pins. Refer to Work Instructions for further details. See above table for PN 2. Install stencil and squeegees. See above table for PN and length 3. Stir solder paste vigorously for 2-3 minutes 4. Apply paste approximately 1“ away from the bottom stencil aperture. See example below: 5. Set batch limit on the DEK to 30 6. Load product: 12688ET 7. Run DEK machine while continuously verifying that the solder bead width is no less than ¼ “. If less than ¼”, re-apply paste. Note: When measuring solder paste at the LSM use ref des RN16, J32, J33, J30, U1. Check solder paste measurement every 20 boards. Top Side DEK Safety Guidelines: 1. Always wear latex gloves for handling hazardous material. 2. A non-metal spatula must be used for removing paste off stencil. This is to prevent damage to the squeegees and stencils. 3. Always check date and time of the solder paste jar being used. Paste must be placed at room temperature for at least 4 hrs before opening. Stencil life of paste is a maximum of 20 hrs. Setup And Tools: Approx. 1” away from bottom stencil aperture solder paste

If UUT or test equipment is damaged, then contact test engineer immediately. 1) Make sure that the spring-loaded barrel bolts are pulled away from the middle of the tester where the UUT is to be positioned (bolts, qty 4). 2) Place the 012686-001 midplane UUT (Unit Under Test) into the middle of the tester. Place it carefully and use the tooling pins that are provided. Also, 4 male pins on the power plates must mate to 4 holes in the UUT. 3) Allow the 4 spring-loaded barrel bolts to be pushed (by their springs) towards the middle of the UUT (from top and from bottom). These 4 pins hold the UUT in place while test / load blades are inserted and withdrawn. 4) Push the qty 4, double-wide I/O test blades (S155) into the UUT from the rear. These should occupy the top 4 of the 5 double-wide slots in the rear. The bottom one is reserved for EMMs (Enclosure Management Modules), not yet used. Use moderate force to mate the test blades to the UUT; a need for excessive force will indicate a damaged connector. 5) Push the qty 16, server test blades (S156) into the UUT from the front. Start from the lower left and work towards the lower right. Then engage the 8 top blades, again from left to right. Have a second test operator guide the mating action to insure no connectors are damaged. Use moderate force to mate the test blades to the UUT; a need for excessive force will indicate a damaged connector. 6) Insure that all 20 test blades are connected via 20-pin ribbon cables, to the TED 2744 “unifier” board. There are 22 connectors on the 2744 v/s only 20 test blades, and so 2 of the ribbon cables will need to connect to TWO (not just one) header on the 2744. 7) Turn on tester power. 8) Push the momentary switch on the TED 2744 test board to start the test. Be sure to hold the button for a few seconds (long enough for the blade “test in progress” LEDs to light, see below). 9) Observe the tester… Test time will be 1.5 minutes. Any RED, FAIL LED on any one or more blades should light the red FAIL LED on the 2744 unifier board. The green PASS LED should light only when all 20 green PASS LEDs on all 20 test blades are lit up. The “RIGHT” LED on all test blades will indicate “test in progress” during the 1.5 minutes. If this “test in progress” LED does not light, in means, bad cable or bad test blade, or the operator did not hold the “test start” button for long enough.

They should each turn ON for the 1.5-minute test, except each one should briefly blink OFF for 1 second, in a pattern walking across the front of the tester, from blade 1 to blade 16. If this patter is not working properly, then RN1 to RN16 (slot ID pull-downs) are probably not soldered or installed properly, on the midplane UUT. This is a temporary visual test until improved test coverage (a “ping test”) is implemented. Here is proper sequencing of the server blades as viewed from the front of the tester: 1 – 2 – 3 – 4 – 5 – 6 – 7 – 8 9 – 10 – 11 – 12 – 13 – 14 – 15 – 16 11) Observe the RIGHT ORANGE LEDs on the 4 double-wide I/O blades to the rear of the tester. They should each turn ON for the 1.5-minute test, except each one should briefly blink OFF for 1 second, twice for each double-wide I/O blade, in a pattern walking down the front of the tester, from blades 1 - 2 to blades 7 - 8. If this patter is not working properly, then RN17 to RN23 (slot ID pull- downs) are probably not soldered or installed properly, on the midplane UUT. This is a temporary visual test until improved test coverage (a “ping test”) is implemented. Here is proper sequencing of the server blades as viewed from the front of the tester: 1 - 2 3 - 4 5 - 6 7 - 8 12) When the green PASS LED lights on the 2744 unifier board, the UUT has passed 13) Power down the tester 14) Pull all test blades out far enough to access the UUT 15) Pull back the 4 spring-loaded barrel bolts 16) Pull out the UUT 17) Repeat the test process with the next UUT FYI notes: Above test procedure is only for site pilot. Later versions of the test will be more complicated, with the use of a test host, EMMs (Enclosure Management Modules), more fans and power supplies, and diagnostics. The red FAIL LED on the 2744 unifier will light if any blade has no power directly from the UUT (or power plates in the case of the server blades) or other power malfunction (such as a failed E-fuse), but DOES have power from other test blades, via the ribbon cables. Log all boards in data collection from Functional Test Results Pass / Fail. Send all failed boards to Debug Technician. Do not tale board off tester until it says Pass Apply sticker after passing Functional Test
