Jan. 31, 2014 Time Contribution Antonio R&d electronics work 4.07 HR 31/01/2014 New components added to the part list. 30/01/2014 Re-assembling a 3-Axis driver using the new PCB and updating the part list with the missing components https://docs.google.com/spreadsheet/ccc?key=0AvKN6G919YgndElQenVpbUZ6UTk1N0liYm4zbGRKbkE&usp=drive_web#gid=5 15/01/2014 Connectorizing the 3-axis piezo finger. Instructions here: https://docs.google.com/document/d/1qGbzFsd7eTMJ2wGnYq7mnx2ik7y9CZoJWg2onIih7BY Proceeding tests, The electronic system is working well, but the frequency limit is lower than we've supposed (about 25Hz using the filtered output, accordint to the datasheet we expect 3x this frequency using the non-filtered output). The fiber is moving on the Z-axis, but we have a XY component working at the same time. I think this is due the bad quality of the actual mechanics and the non uniformity of the springs. I've also found a mistake at the top_base, it should the rotated by 45 degrees to be aligned with the XY-axis! 07/01/2014 Proceeding a heating test on the 3-axis PDm200: (https://docs.google.com/spreadsheet/ccc?key=0AvKN6G919YgndEEyamtKX1ZFU0Zkb1pIUTdFS2hybWc&usp=drive_web#gid=4) 1) no external dissipation, box closed, sensor on the black heat sink, measuring each 5min 2) Using the thermal pad with adhesive (H48-6G-20-20-2.6-1A) and NO thermal paste connecting the PDm200 to the aluminum box No load or input 3) Using the thermal pad with adhesive (H48-6G-20-20-2.6-1A) and DO using thermal paste connecting the PDm200 to the aluminum box No load or input The tests showed the need of using the Thermal Pad but the use of Thermal Paste have not increase the dissipation capacity. A second test without thermal paste didn't have the same result, probable because the coupling between the 2 surfaces, a thicker thermal pad should solve this problem. The thermal pad data sheet shows that some pressure is necessary to obtain an optimal response. 06/01/2014 Redesign base PCB to fit 10cm long specification and reallocate components: Base_PCB_3channel.SLDDRW Design the Front and End plates: K End Plate.SLDDRW K Front Plate.SLDDRW Board_2.SLDDRW PDF versions saved here: https://drive.google.com/?tab=mo&authuser=0#folders/0B_KN6G919YgnTmRpNVQyYU1XR1U 10/12/2013 (1h7m) search of components: BNC cable, piezo buzzer, thermal adhesive pad R&D work on the Piezo Driver Make Piezo one/two/three-channel electronics Manipulator Driver - Component - Product - Electronics: 2ax MPM-S1
