Shameless plug for my long post in the general thread, I found some Panasonic production line estimate numbers from a guy who claims to have friends/family working for Panasonic. Appears to support the previous Panasonic battery line issues we've heard.
2017 Investor Roundtable:General Discussion
This is a brilliant post, and probably spot on. I work in high tech high volume semiconductor manufacturing the process engineering side. I’m a part of regular production meetings along with equipment engineering as necessary support to the production team. All three of these teams are crucial to making production ramp goals.
I suppose my comment is just to commiserate, and to say that all this information sounds completely accurate. The comment about lines being down for months waiting for a 3c o-ring may not be precise, but tools (and therefore lines) down for parts with long lead times is a regular occurrence when bringing up first in fab or custom tools.
We have been trying to ramp our fab by 40% from January run rates all year, and are only about half way there. This is in a fab that is 20 years old and have very established tooling, procedures and parts. Supplier issues requiring second source part qualifications routinely plague us, and training large amounts of staff while promoting the experienced staff off the floor creates huge experience vacuums.
Suffice to say this post has triggered flashbacks, and has completely opened my mind to what is really happening in a huge brand new factory. We should all be focusing on the GF and watching closely for the Panasonic + Tesla partnership to work through these issues as a top priority, but also realize these type of bottlenecks are structural and will not be ‘solved’, only gradually improved.
Silver lining: EVERY other company attempting a huge new high volume battery factory will likely encounter almost the exact same challenges. These are unfortunately inherent to the complexity of the task. While our ramp may be slowed, no other company will be able to simply leap-frog us as a result. Based on my experience, the advantage will come from the company with the most supportive company culture, as the sheer output required from employees will burn through humans like tissue paper. Panasonic’s culture is the wild card in this equation.
Thank you again for such an eye opening post!!
