-    * Process specifications ​ +=== TL;DR === 
-    * Can I add soldermask or silkscreen?​ +The Hive is home to 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:
-    * Is there recommended DRC/CAM file I can use? +
-    * Do I have to be with my board during ​the entire fabrication process? +
-    * How long does it take to make a board? +
-    * How long does electroplating take? +
-    * Can I somehow reserve time on the equipment?​ +
-    * Do the tools have additional capabilities?​+
  
------+  ​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.
  
-=== Introduction ​=== +Training is completed for the electroplater //​separately//​ from the ProtoMat and the ProtoLaser, which are done together. Both training sequences follow the same basic steps.

-No, even better: we’ll train you! That’s right, ​for mere four hours of your time, you will gain the ability to make as many PCBs as you want for free and can reserve time on the equipment! What a great deal, what a time to be alive. Only making one board? It can take several tries to get it right. In other words, if you think you only need one board done, you might actually need two! +No, even better: we’ll train you! That’s right, ​watch few videos and demonstrate that you watched them to gain the ability to make as many PCBs as you want for free! What a great deal, what a time to be alive. Only making one board? It can take several tries to get it right. In other words, if you think you only need one board done, you might actually need two (or more - how often is a design perfect the first time?)

 +** What about the electroplater?​ **\\
 +We used to do the electroplater training during the combined training, but we discovered that most users never used the plater, and most users didn't care. So we've separated the electroplating training off into a separate training sequence that comprises a single video, quiz, and checkoff, and allowed us to significantly reduce the training time for the ProtoMat and ProtoLaser. If you're interested in getting training on the electroplater,​ you can head on over to SUMS and locate the training requirements for the tool (LPKF Contact S4 electroplater) to get started.

-If you have no idea what SUMS is, 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.

-** How do I join a training session OR request a new one? **\\ 
-If you haven’t been to The Hive, you’ll need to join our “Equipment Group” first: 
-  - Go to sums.gatech.edu and login (button is on the top right of the screen). 
-  - In the main toolbar on top, click "​Equipment Groups"​ > "​Equipment Groups List". 
-  - Search for "The Hive" (no quotes). Click the link. 
-  - Click "​Become a member"​. Follow the prompts to join. Note that the "​exam"​ is simply our liability policy. 
-Congrats! Now you can begin the PCB training process. 
- 
-//To register for a training session that has already been created:// 
-  - Go to sums.gatech.edu and login (button is on the top right of the screen). 
-  - In the main toolbar on top, on the right, click "Set Active BG/​EG"​. Make sure your Billing Group is "​Interdisciplinary Design Commons"​ and your Equipment Group is "The Hive". 
-  - In the main toolbar on top, in the middle, click "​Equipment Groups"​ and then "Hive - Training"​. 
-  - You should see all the available training sessions that The Hive is offering through the SUMS system. Sign up for the one that works for you. 
- 
-//If there are no training sessions, or none of the scheduled ones work for you, you may request a new one:// 
-  - Go to sums.gatech.edu and login (button is on the top right of the screen). 
-  - In the main toolbar on top, on the right, click "Set Active BG/​EG"​. Make sure your Billing Group is "​Interdisciplinary Design Commons"​ and your Equipment Group is "The Hive". 
-  - Somewhere in the main area of your main screen, you will find a section called, "Find training requirements"​. Click it and search for "pcb plotter"​ (no quotes). Select S116.PCBPlotter-01 to get to the PCB plotter'​s training requirements screen. 
-  - Click on "​Request a new training session"​. Please make a selection for all five slots. If you are available more times, add those in the notes section. More availability is better than less! However, even though you have requested one, it is possible that none of these times will work for our trainers (we’re students too!). If this is the case, we will try to email you to find another time.  
  
-Training sessions ​can be held anytime (including (and preferably!) ​when The Hive is closed)+** Ugh, this sounds like way more work and time than I'm willing to dedicate to this. Do you have any recommendations for professional fabrication houses?​**\\ 
 +We don’t officially recommend a specific fabrication houses. All of them have positives and negatives. The following is a very incomplete list of fab houses that we've used with varying levels of success. 
 +  * You can use [[https://​pcbshopper.com|PCB Shopper]] to compare prices across a number of different fab houses. 
 +  * [[https://​jlcpcb.com/​|JLC]] and [[https://​allpcb.com/​|AllPCB]] are two Chinese companies that offer super fast turnaround and super low prices with a wide range of capabilities and good results. But since they'​re made in China, there may be shipping and IP issues. 
 +  * [[https://​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. They also can make solderpaste stencils through their affiliates at [[https://​oshstencils.com|OshStencils]]. 
 +  * [[https://​4pcb.com|Advanced Circuits]] ​is another American-made fab facility that has a much more extensive list of capabilities than OshParkIt's more expensive, but the quality is higher, and the turn-around times can be same- or next-day, if you're willing to pay for it. They also have deals on rectangular 2- or 4-layer boards, and deals for students. 
 +  * [[https://​www.epectec.com/​|Epec Engineered Technologies]] is the most expensive of this list, but also the highest reliability and widest range of fabrication options. If you need a 16 layer board with super-fine pitches and tolerances and varying copper weights for the internal stack with specialized prepreg, and you need 1000 pieces assembled tomorrow, these are your people. (Okay, that's an exaggeration,​ but seriously, for non-standard work, or precision standard work, Epec is great.)

-**What ​should I expect out of a training ​session?**\\ +**Videos? ​What happened ​training ​sessions?**\\ 
-Training ​sessions ​cover the fabrication process of basic 2-layer copper circuit board using the PCB plotter ​and PCB laseras well as discussion of the electroplating process for viasTraining sessions do not address board design or layout. For questions regarding design, find one of our PCB MPIs.+The live in-person training ​sessions ​were major drag on both Trainer ​and User timeand they were significant deterrent to many people getting trained on the toolsThe video format allows users to train at their own pace when they have time, not when we have time.
  
-**Do I have to have any prior knowledge before coming to a training session?**\\ +**What do the videos cover?**\\ 
-Nope! However, if you are unfamiliar ​with PCBs, we recommend reading up on some basics on the internet before ​your trainingWe also have PCB Fabrication Guide that might be of interestThis waythe training session will (might?) make more sense.+The standard process training videos ​are broken into three parts: part 1 covers process setup and drilling; part 2 covers etching ​with the laser; and part 3 covers routing and cleanup. These three total about an hour of time, which you can do at your leisureThe electroplater video is roughly ​half hour, and comprises just a single video that covers the process setup and the electroplating.

 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.

-** Process specifications **\\ 
-The Hive's PCB fabrication tool suite has the following capabilites:​ 
-  * //​Substrates://​ FR4, Rogers materials, polyamide, among many others. 
-  * //Copper thickness/​weight://​ No limit, other than processing time. 
-  * //Trace width (minimum)://​ 2 mil (0.05 mm) 
-  * //Trace pitch (minimum)://​ 1 mil (0.025 mm) 
-  * //Drill holes (minimum diameter)://​ 6 mil (0.15 mm)  
-  * //Slot:// yes, use overlapping drill hits 
-  * //​Plating://​ yes, standard processing time of 3 hours will plate approximately 12.6 um of copper 
- 
-** Can I add soldermask or silkscreen? **\\ 
-We have the capability to apply soldermask and silkscreen, though we //do not// recommend attempting this process - it's time-consuming,​ UV- and temperature-sensitive,​ and unnecessary to a complete circuit board. If you need soldermask or silkscreen, consider sending your design to a professional fabrication facility. ​ 
- 
-For those who would like to attempt this, instructions are available on our [[pcb-mask-silkscreen-SOP| mask and silkscreen]] page, as well as in the "​Manuals/​Instructions"​ drawer next to the tools themselves. ​ 
- 
-**Is there a recommended DRC/CAM file I can use?**\\ 
-Yes!

-  - [[https://​drive.google.com/​open?​id=1WzzpPwXMDUg5DD4iUzenZINrzRG0kSn4|CAM]] 
- 
-**Do I have to be with my board during the entire fabrication process?​**\\ 
-Yes! You must be present for the entire process. This is for safety reasons. PIs have the authority to cancel any unattended boards. You may, however, leave the space //if and only if// you leave a note with a phone number and accept the possibility that something may happen to your product while you're gone (because PIs are not watching your process). ​

-**How long does it take to make a board?**\\ 
-It depends on the size and layout of your board. A small board with no electroplating (i.e. no vias) can easily be made in under an hour, while a very large board with lots of copper removed can take over 4 hours not including electroplating. 
- 
-**How long does electroplating take?**\\ 
-Between 2 and 3 hours, regardless of board size. This will plate between 8-15 um of copper onto your surfaces. Less than this processing time can cause unreliable vias with variable thickness of the plating. ​ 
- 
-**Can I somehow reserve time on the equipment?​**\\ 
-Yes! Although you are not required to, we //highly// recommend that you do as it guarantees equipment priority. You may reserve time up to 96 hours in advance though SUMS. See the SUMS Guide for more details. 
-  - Go to sums.gatech.edu and login (button is on the top right of the screen). 
-  - In the main toolbar on top, on the right, click "Set Active BG/​EG"​. Make sure your Billing Group is "​Interdisciplinary Design Commons"​ and your Equipment Group is "The Hive". 
-  - On the main page, locate the Schedule section. Under the drop-down menu that says, “My Schedule - Select a tool to schedule time”, select the tool in question. Note that you cannot reserve time on a tool until you have completed training for it. 
-  - Click and drag on the calendar itself to reserve time. Release the mouse button to bring up the reservation screen. You must enter a description in order to reserve time! Click “Save” to save the reservation. 
- 
-We highly advise you to schedule time on all the tools you’ll need, i.e. if you’re fabricating a standard board, you should reserve time on both the Plotter and the Laser. If you do not, and someone schedules time on only the laser, they have priority on the tool. 
- 
-//​Reservations are limited to the following://​ 
-  * Non-PIs (i.e. those who are not volunteers at The Hive) may schedule a maximum of 4 hour block per tool per day during The Hive’s open hours, and up to 4 days in advance. 
-  * PI’s may schedule up to 8 hours per tool per day, up to 7 days in advance. 
- 
-** Do the tools have additional capabilities?​ **\\  
-//NOTE: The following capabilities are allowed in the spec of the tool, but we do not support these functions, meaning that our PIs and MPIs do not have experience with them, so you will be on your own if you attempt any of them!//\\ 
-The ProtoMat has the capability to do aluminum and plastic 2-dimensional milling. The ProtoLaser can etch a very wide variety of substrates and films. The electroplater has the ability to do tin plating (though we don't carry the necessary solution by default). We also have the LPKF ProConduct system that enables manual electropating of individual vias for RF PCBs (proceed with caution here). ​
