Abra AK-120 Quick Start Manual

D.I.Y L.E.D Cube with Touch Function
Level: Expert AK-120

A brief Intro to SMT/SMD

So far the components that were selected are
all 0805 SMT package size. This is a common
dimension for Surface mount components.
Along with the 0603, theses will be the
common dimensions you may encounter with
the introduction to surface mounting.
The Resistors are usually denoted with a black
body and a number written across the unit to
reveal its value. Capacitors on the other hand
have a beige body and no writing on them. So
you don't want to drop or mix them up.
When soldering, keep all the components in
their packaging and avoid using a de-soldering
pump as the tiny components can be sucked up
from the pump.
Work over a clean environment or you may end
up spending the entire build time looking for
the components.
