Place the heatsink and the
regulator on the PCB.

Ensure that the hole of the
heatsink and the one of the
regulator correspond to the hole
in the PCB.

Use heatsink compound to en-
sure good heat dissipation.

Fix the two components with an
M3 bolt and nut.

Now, the regulator may be sol-
dered.

6. Voltage regulator
