{{WarningBox| DON'T USE FORCE! NEVER! Some parts are really delicate, specially flat cable connectors (FPC), and you could easily break something if you are brute. Assembling the V5 unit is not difficult at all, but it's a clock-maker work. A beginners one that almost everyone could do, but clock-maker's task anyway. if you are not very used to manipulate this kind of stuff, please, proceed slowly and think twice to do it once.}}

Be careful when opening the screws bag. Some of them are really small and you could easily lose them. Please, don't dump them on the table's surface or on top a piece of paper. We recommend to dump the bag's content in an small tray, so you can look and take the parts easily, but getting them well confined so they can't be easily lost.

Put special care to the 4 tiny headless screws used to secure the knobs. They are really small!! You could screw them into the knobs and avoid they get lost during the build process.

Pay special attention to the 4 tiny headless screws used to secure the knobs. They are really small!! You can screw them into the knobs as a first step to avoid losing them during the build process.

This is a good time to get familiarized with the different screw models we will use. Take a closer look to the content of the screws-bag and try to identify:

'''3.''' Open the RPi4's DSI connector by softly pulling both sides of the tiny black tongue at once. When it's totally open, push the ribbon cable inside, straight, with the blue side facing out. When the cable is totally inserted, close the connector by pushing the tongue with 2 fingers, one of each hand. Pay attention to ensure the cable does not move out of the connector. If it's not well inserted or not straight, repeat the operation until it's OK.

Zynthian V5 gets a 25% extra power from the RPi4 by overclocking the CPU up to 2 GHz. For this to work properly, we need to remove the heat generated by the RPi4. As we don't want a noisy fan, prone to failure,  pushing dust inside our nice case, we are using the aluminum case as a huge heat-sink. This is achieved by the thermal block, a solid aluminum block that closely contacts with the RPi4's chips and serve as a heat-highway to the aluminum case bottom, and from there, to the rest of the aluminum case. When your zynthian V5 is working hard, or when external temperature is high enough, you will note the V5 case is hot. This is good because it means the thermal block is doing its job of transferring heat from inside to the aluminum case body, where it's dissipated to the ambient environment.

Having understood all this, you may realize '''this is a key step for getting your V5 working at 100%''' of its capacity, so don't be in a hurry and take your time to do a good job. Let's start!

'''7.''' Finally, stick the remaining piece of thermal pad (27 x 20 mm) on the contact surface in the external side of the thermal block. That is, on top of the "tower" with 2 tiny holes. Follow the same procedure you already did with the 3 smaller pieces, but don't remove the transparent protective sheet yet. You will do later, when installing it in the aluminum case bottom.

Also note that the display flat cable should pass thru the rectangle hole in the main board, like in the photos (zoom if you have doubts).

This little piece of plastic is just to avoid you accidentally drop the micro-SD card into the aluminum case without getting inserted in the SD-card reader.

This little piece of plastic is just to make sure you can't accidentally push the SD card into the gap between its slot and the case, thus losing it.

But ... can this happen? Well, it's not easy, but we have printed this nice piece of plastic for some reason ;-)

Remove the first protective sheet (the thin and baggy one) and leave the second one untouched. After this, flip the display and remove the 4 yellow protective sheets from the outer spacers. You could use your fingernail or a cutter for this operation.
