 +=== TL;DR ===
 +The Hive is home to a suite of equipment that enable our users to fabricated PCBs without much manual work. Once trained, users have access to these tools and all the materials we have as long as the space is available. Training is handled through SUMS, and is done in three steps:
  
-=== Introduction ​=== +  - Training videos - watch them all on your own time and at your own pace. 
 +  - Quiz - ten questions, get nine to proceed. 
 +  - Checkoff - show off what you've learned by fabricating the board from the training videos in a one-on-one session with a trainer. Complete it in two hours, and the tools are your for the using. 
 + 
 +Read on for more details about this process, or [[https://​www.sums.gatech.edu/​SUMS_React/​View_Equipment_React?​DepartmentId=87&​ToolId=1998|head directly to SUMS]] to get started.

-If "​SUMS"​ makes you think of arithmetic, have no fear. SUMS (Shared User Management System) is a user access control system made here at Tech that The Hive uses to control access to some of the more sensitive or complicated tools. For PCB fabrication,​ it is also used to manage training and checkoff sessions, and users can schedule time on the tools through it, as well. You can get many more details in our [[https://drive.google.com/open?id=1XLLOS43sQd6rzWll8cAxkvRiArmIGGvpcC-y9uXCOek|SUMS Guide]].+If "​SUMS"​ makes you think of arithmetic, have no fear.

-  * [[oshpark.com|OshPark]] is the cheapest USA-based fabrication house because they aren't actually a fab house - they'​re a middleman to another fab house. Basically, they collect a bunch of designs, and when they have enough, they all get sent off. They'​re well-known for their purple PBCs, and their capabilities are growing all the time.

 Probably not. It is, however, at the discretion of your trainer. If the board is small, simple, and on FR4/FR5, (i.e. very similar to the training board), then it might be fine. However, large boards can take an hour or more to etch just one side. Since most boards are larger than the training one, you will likely have to stick with the training board. It will be easier for everyone (especially if it fails), and afterwards you can simply schedule time on the tools to fabricate whatever you’d like. Probably not.
