Hi EMS 188 Project Teams,
I was able to track down the shipment and I have the materials in my possesion. I received what appears to be a power supply and two sets of MMIC assemblies. One carrier has a green post-it on the from and has 3 assys. One did not make it, the chip came off the shim. I'm not sure the other two can be used for thermal conductivity testing as the material is well over the edge of the shim. I'll ask about that. The other carrier has 5 assys.
Can you please tell me 1) what I have here (i.e. which ones are Sn plated and which ones are Au plated and what shim materials they are mounted on, in other words, a detailed explanation of what was sent) and 2) which ones are targeted for thermal conductivity testing so I can have them mounted and bonded up. Are some of these on Mo shims and some on Cu? If so, how can I tell them apart?
You can either send me an e-mail or we can talk about this at class tomorrow, but the clock is ticking. To maximize the efficacy of your field trip on Friday, I should get the thermal conductivity assys mounted and bonded in advance. The more time we have for that the better.
Finally, I have not heard back yet when you plan to arrive and how long you plan to stay. I need to advise the engineers that are supporting this effort.
Best Regards,
Mike
I was not included in this discussion. In class I asked for us to leave at 10 so we would arrive at 12
