Working Boards
2016-10-06:
This week Medusa Computer Systems received a first fully functional board from the assembly company.
The bus drivers had been removed from the computer, isolated with Kapton tape and soldered back on afterwards. The system is now running perfectly and the chips are not getting warmer than 45 degree Celsius even after several hours of operation.
As we had suspected, contrary to the spec sheet, the bus drivers had become conductive after a few minutes runtime. The Kapton tape currently in place on the bottom side of the thermal pads isolates them completely, while still allowing for heat dissipation. A more detailed technical explanation will follow as soon as we are in the mood for an in-depth article in the coming weeks. ;)
The good news, then, is: Provided that there will be no other unexpected catastrophes, we will be able to deliver the first computers end of October! The newly equipped systems will be delivered to us in 2-digit batches every two weeks, and then checked thoroughly one by one, before they are sent out. The pre-orders will be processed in the order they were made. So, all those who pre-ordered will soon be contacted by us.
Again, kudos to all of you - the best community in the world! In the last months of uncertainty there was not a single bad word, only encouragement, understanding and trust from your side. Thanks!
Here is also a picture of the heat camera for comparison. The upper one shows the version with the new Kapton tape.
