Important notes before getting started
Please refer to https://docs.google.com/spreadsheets/d/13xwf5e_5ykVG42IyagU8_QQN1EIVY4WaOXtT-j7fQOg/edit?usp=sharing to ensure you are using the correct hardware. When a module is completed, please update the number of modules created in the inventory page of the sheet so we know what we are running low on.
Procedure:
Add heat set inserts to the appropriate locations
Side note: M2.5 heat-set insert holes on the top module cover could be bigger to make melting them easier (not urgent)
Bend sigma-clad tabs after fitting them to the top plate
Place Sigmaclad between top plate and top cell holder into appropriate location (should lock in place with the side protrusions)
Attach the top plate, using the heat set inserts previously installed with M3 screws
Bend the Sigmaclad terminals as close to the 3D-printed wall as possible. Should look like the photos below
Remove the top plate and use MG Chemicals 8800 to attach Sigma Clad to the top cell plate (the Sigma clad should align flush with the top cell plate holders)
Begin with measuring the materials in a 2-to-1 ratio of liquid A and B, respectively. Approximately, 2.5mL of A and 1.25 of B should be sufficient for this step.
Use the heat gun to apply heat to both liquid A and B to rid any air bubbles
Pour mixtures into the same container ensuring to scrape excess material from the side of the container to get as much as possible
Use heat fun again to briefly flash heat (not too long as the mixture will set faster after cooling)
Mix mixture for 2 minutes
Wait until the material has reached a viscous state that is easier to work with (still liquid but congeals together better than the freshly mixed liquid)
Gently place the mixture onto the top cell plate (preferably with a popsicle stick or something to apply)
Press on the Sigma clad to their according sides of the module
Use clamps to hold down Sigmaclad, placing popsicle sticks down across the material ensures more of the surface area of the Sigmaclad contacts the cell plate
Leave for a minimum of 2 hours before moving, it takes 24 hrs to fully set
Attach standoffs to the bottom cell holder
Begin by using LOCTITE ____ on the interior of an aluminum standoff
Place LOCTITE ___ on the appropriate screw for the stand-off (6-32 Thread Size, 1/2" Long Bolt)
Screw together the connections using an allen key to make sure it is secured
Place cells in the correct placement
Begin with filling the first parallel line with cells, positive side upwards. Positive ends of the terminal should be where the 3D protrusions (bumps) are on the 3D print
The cells should run in 8 parallel and 4 series looking like the image below (no standoffs here as it is an example):
