Equipment



The Computer Workstation • 3D Printer - Bambu Lab P1S



This is a standard computer managed by the ISG. It is equipped with MS Office, Target 3001 Design Software and Firefox. You may want to check your BOM or the assembly.csv or whatever seems necessary. Use your D-PHYS credentials to log on. The computer is equipped with an SD card reader/writer in order to communicate with the pick and place machine. It is a good idea to have your own SD card with you.



• Check with the camera that the printer/bed is empty before printing.
• Do not "home" the bed when you are not sure that it's empty.
• Remove the printed line at the edge when picking up your sample.
Not sticking to these rules might damage the printer.
In case of questions please consider sending an email.

Only official tasks ... which we will not check :-)

The Cleaning Workstation



Is equipped with a subsonic cleaning unit. Elmasonic S30 H. Very often this is not necessary ! The cleaning liquid is Elma Tec Clean A1 Ultrasonic Cleaner Solution. From Big C, (Best.-Nr.: 039616-62).

Elma tec clean A1 should be diluted to 3-10% with water before use. Tec clean A1 is formulated to be easily and thoroughly rinsed off with water, leaving no chemical residue after rinsing with distilled or deionized water. The mildly alkaline solution can be used over and over until it begins to lose effectiveness. Tec clean A1 is water-based and biodegradable.







The Repair / THT Assembly / Hardware Workstation



This is a workstation to manually assemble and solder THT components. Some basic equipment like power supply, waveform generator as well as a soldering station / desoldering station are available.









The BGA Inspection Workstation



This workstation is equipped with a short wave scanner. You may store pictures on an USB memory stick. It is a good idea to have your own one with you. Anyway, for urgent / emergency use, a small batch is available. Bring them back, as we consider you to be a honourable person. It is considered evil to scan your colleague's sandwich for ingredients.
